How to fix a low beam headlight

A blown out or low beam bulb has several safety disadvantages.

Firstly, you’ll find it difficult to see when driving at night. This has obvious safety ramifications for yourself, your family and other road users.

Secondly, with low beam lights you’ll be forced to use high beam. Other drivers will find it difficult to see the road in front of them while they’re being blinded by your high beam.

Fixing a low beam headlight is a straightforward process that the majority of vehicle owners are capable of doing themselves with a few tools.

After replacing the low beam headlight if you still experience problems, your vehicle might have more serious electrical wiring problems that will need to be fixed by a professional mechanic.

4 Steps to Fix a Low Beam Headlight Bulb

1. Find the blown out bulb

When driving at night, you can easily tell that a headlight bulb has blown out.

However, to identify the bulb which has blown out, leave your headlights on and get out of the vehicle to see which beam is not as bright as the others.

Some vehicle models use a single bulb for both high and low beams while others use different bulbs for high and low beams respectively.

If the beam on the side is completely out, this is an indication that the car is using one bulb for both high and low beam.

After you have identified the beam that has a problem, you can easily replace the blown out bulb.

It is not a must that you replace the bulbs on both sides of the car if it’s only one of them that isn’t working.

If both the high and low beams are on the same side and they are both not working, your car’s electrical wiring might have a problem that is preventing power from getting to the bulbs.

2. Buy the replacement bulb

Your car’s year of manufacture and model will determine the type of bulb you purchase to replace the low beam bulb that is not working.

Provide these details to the clerk at the automotive parts store so that he can give you the correct bulb to use on your headlight.

Note that the headlight codes are a mix of letters and numbers such as H11B or D311 etc.

3. Get your tools ready

Replacing a low beam bulb can involve more time and work than you expect. In some cars, you will not need any tools, but in others, you will need specialised tools to help you remove the components, the beam bulb under the hood, and sometimes even the bumper.

For a list of all tools that you need while servicing your car, refer to the car manual.

However, most cars require just a screwdriver or no tool at all to gain access to the headlight housing.

After reading through the service manual, inspect your headlight to ensure that it looks just the same as explained in the manual.

If you bought a used vehicle, components such as flat head screws might have been replaced.

4. Disconnect the negative terminal on the battery

Before you disconnect the battery, make sure you label the side where your blown out bulb is located.

Once you disconnect the battery, the headlights will go off.

Use your hand or socket wrench to loosen the nut holding the negative terminal of your car’s battery.

You do not need to remove the nut completely. Make it loose enough so that you can be able to slide off the cable from the terminal.

Fasten the cable on the side of the battery to ensure that it doesn’t reconnect to the terminal when you are working.

You don’t need to disconnect the battery’s positive terminal as the circuitry is not complete with the negative terminal loosened.

How to Remove an Old Headlight Bulb

1. Remove the trim pieces

Modern vehicles come with a piece of plastic trim that keeps the headlight assembly separate from the engine bay. You will need to remove the trim in order to access the headlight bay.

In newer vehicle models you will need to remove the front bumper that covers the headlight in order to remove the old bulb.

Refer to the vehicle service manual to understand which pieces of trim you will need to remove to be able to access the headlights.

If you remove the plastic trims ensure that you don’t break the snaps and fasteners that hold the trim in place.

If you accidentally break some of the snaps and fasteners on your car, you can replace them from your local auto parts store.

3. Find the headlight holder

Modern vehicles use plastic housing for the headlights.

In some other cars, you will find that the headlight bulb is held in place using a plastic bracket or metal.

Your vehicle’s service manual will indicate how to locate the holder and how to remove the headlight and wire pigtail from the plastic housing.

Modern cars have made it easier to remove the headlight from the housing as all your required to do is rotate the headlight 1/4 turn in the clockwise direction and then pull it from the housing.

If there are any nuts to be removed, make sure you keep them safely until you reassemble that portion or your vehicle.

Note that in some cars, you will need to remove the entire headlight assembly.

4. Disconnect the cables from the headlight

Your headlight bulb will have wires attached to its base. To disconnect these wires, put the plastic clips and the cables in a safe place. Avoid accidentally removing them from the headlight bulb housing which will cause your headlights to malfunction.

Be extra careful when pressing on the clips as they are usually made of brittle plastic. It can break easily.

If you accidentally break the clip, you can secure it using electrical tape or buy replacement clip and then solder it in place of the old one.

5. Remove the headlight bulb from the bulb housing

When removing the bulb from the bulb housing make sure you hold it from the base as touching the glass top of the bulb may break it and cut your hand.

Remember that a broken bulb is harder to remove from the bulb housing.

If you accidentally break the bulb, use pliers to remove the broken bulb from the bulb housing. Never touch a broken bulb with your hands.

Discard the blown out bulb into the trash once it is completely removed from the bulb housing.

A blown out low beam bulb can make it difficult to see at night and driving with your high beams on all the time can make it difficult for other drivers to see. Fortunately, fixing a bad low beam is a straight forward process in the majority of vehicles that can be done by most people without just a few hand tools. If replacing your headlight bulb does not work, there may be an electrical issue in your vehicle that should be addressed by a professional.

A bad or blown-out low beam will force you into putting on your car’s high beam if you want to see the road ahead of you at night. Whereas, according to the USA traffic law, if your high beam is on while you are at about 300ft from the vehicle ahead of you, you will be fine. Aside from that, driving with a bad low beam can put you in danger as it can make it harder for you to be spotted quickly by other oncoming vehicles especially at sharp bends.

How to fix a low beam headlight

Fortunately, fixing a faulty low beam is straightforward and can be done by anyone with or without previous mechanical experience. However, if replacing the faulty bulb of the low beam does not solve the problem, the underlying cause might be an electrical issue and you will need a professional. But, if the primary cause is due to a foggy headlight lens, then you can easily restore the lenses using a headlight restoration kit.

Fixing a low beam headlight in three steps

Step one

  • Identify the faulty bulb

How to fix a low beam headlight

It’s easy to tell when you have a blown-out while driving. However, confirm which of the bulbs is out by parking your car away from the road and checking your headlights while the ignition is on. Then, get back in your car and switch on the high beams. Some cars make use of a single bulb for both low and high beams. If the high beam on the same bulb works, then it’s an electrical issue. If the high beam doesn’t work, the bulb is bad and you should consider replacing them.

Step two

  • Buy a replacement bulb

How to fix a low beam headlight

The next step is to buy a replacement bulb at your earliest convenience. To make sure you don’t repeatedly go back to your local auto part store due to mismatched bulbs, it’s important that you buy an exact match for your car’s headlight housing and model. Car headlight bulbs are usually labeled underneath the base in letter and numbers like H1, H2, H7, H11, and so on. Check the codes or numbers on the faulty bulb and buy a replacement with the exact same codes and letters.

Step three

  • Reinstall a new bulb

How to fix a low beam headlight

Before taking your new bulb out of its packaging, I recommend you wear gloves or use a tissue. This is because the oil on your palm can compromise the glass of the bulb and cause it to burn faster – thus, reducing its lifespan. Keep your gloves on or the bulb in a tissue as you place the new bulb inside your headlight housing. If you would like to know how to change car headlights, check out our previous posts.

Now, make sure that the bulb is well-seated firmly in the headlight housing and ensure you don’t apply pressure so you don’t break or crack the bulb.


Car headlights are vital components of every vehicle and as such, it’s important to ensure your vehicle’s headlights are working perfectly. Inspect your car driving and maintain your car headlights regularly.

      Driving without working headlights is, to put it mildly, a bad idea. After all, the low beam headlights help you see when visibility is low–and they help other cars see you, as well. If your low beam headlights aren’t working, but your high beams are, you’ll still need to bring your vehicle to an authorized Subaru service center immediately.

      At Carr Subaru, we’re dedicated to giving you valuable information on your Subaru. Below are four reasons your low beams may not be working, even if your high beams are.

      How to fix a low beam headlight

      4. The Bulbs Are Burned Out

      It’s highly unlikely (though not technically impossible) that both headlight bulbs would burn out at the same time. However, if both of your bulbs have burned out, there’s a more likely explanation. Modern headlight bulbs are brighter than they used to be–bright enough that you may not notice much if one burns out. But if the second one burns out later, you’ll be sure to notice!

      How to fix a low beam headlight

      3. A Fuse Has Blown

      If the bulbs themselves aren’t to blame, they may have failed due to a blown fuse. Replacing the fuse may solve the problem. However, if the fuse burns out again, your headlight failure may be due to the next issue.

      How to fix a low beam headlight

      2. The Wiring Is Faulty

      If the fuse quickly burns out again after having been replaced, there may be a deeper wiring issue. However, wiring problems can exist without a blown fuse. This means that bad wiring could cause your headlights not to work, even if the fuse is still intact.

      1. The Headlight Relay Is Broken

      When you flip the switch that turns on your headlights, the switch actually activates a relay, which then supplies the headlights with the power they need. The high beams and low beams usually use different relays; this means that, if only your low beams have gone out, the low beam relay may have been damaged. If this is the case, it will need to be replaced.

      Here’s how to save money by fixing it yourself.

      How to fix a low beam headlight

      It’s worse than running at night with one eye closed: You’ve lost the illumination from one of your headlights. Either a bulb has burned out or a minor accident has claimed the lens, the reflector, or perhaps the lamp’s entire housing. And besides the obvious danger, there are also the risks of a citation from a sharp-eyed law-enforcement officer and the possible gouge from a repair shop’s hourly rate. But you can handle the situation yourself, saving precious greenbacks in the process while feeling the warm glow of accomplishment by replacing a broken headlight yourself. We at Car and Driver know you can. Here’s how to change a headlight:

      How to Replace a Headlight Bulb

      Fortunately, it’s often easy to change a headlight. Most of today’s halogen high-intensity-discharge (HID) or light-emitting-diode (LED) bulbs are simple to replace. They are held in place by thin wire clips or rotating bayonet-style retainers. They can be quickly popped out from behind the headlight housing, unplugged from wiring, and swapped for a working bulb. But in order to change a headlight, you must first identify the type of bulb you need. The first place to look is in your owner’s manual.

      How to fix a low beam headlight

      If the manual is missing but you know the make, model, and year of your car (you do know that, don’t you?) you can consult with a counter person at an auto-parts store or refer to the headlamp booklet that usually resides in the parts store’s headlamp aisle. And finally, you can always pull the bad bulb and bring it to the store for reference.

      How to Extract the Bulb

      You can usually gain access to the headlight’s bulb by simply opening the hood and removing the lamp connections at the back of the headlight housing. Some vehicles may provide added service space through small hinged or rotating panels inside the front wheel wells.

      A few tricky models, however, may require removal of various splash shields, air-cleaner housings, and even washer-fluid bottles for full access before you can change a headlight. That’s why we’d suggest keeping a pair of mechanic’s (or latex) gloves, a flashlight, a flat-bladed screwdriver, a small box of sockets, and a pair of needle-nose pliers handy.

      How to fix a low beam headlight

      Old-school square or circular sealed-beam headlamps are different and larger but very easy to replace. They’re usually retained by a thin metal ring screwed into the lamp’s shell assembly. The retention ring’s screws are easy to loosen from the front of the car. But sometimes, other bright front-end trim must be removed first. A harness plug under the hood at the back of the lamp slides on and off the lamp’s copper terminals.

      Remember This about New Bulbs

      How to fix a low beam headlight

      When you change a headlight, it’s critical to avoid touching a new bulb’s glass, since contamination by the natural oil from your skin and even small amounts of dirt will cause early failure. Use a bit of dielectric grease (available at an auto-parts store if it doesn’t come with the bulb) for a weather-resistant connection on all lamp plugs and terminals. And try not to confuse headlamp-beam adjustment screws for the usually smaller retaining screws.

      Replacing a Headlight Housing

      How to fix a low beam headlight

      If the lamp’s lens is broken, if the lens is super cloudy, or if an accident has damaged the housing, things are more complicated. You’ll want to replace the entire headlight unit, referred to as a housing. These molded housings are clipped or bolted to the front end’s metal radiator support. At the back of the housing are the wiring-harness connections, which must be removed. And unfortunately, in some cases (for example, versions of the Ford Fusion, Chevy Malibu, and Toyota Camry), the front-bumper fascia must be loosened or removed to reach the housing’s fasteners.

      We’d suggest purchasing a repair manual or at least watching multiple YouTube videos for housing replacement specific to your vehicle. (But be careful—these gritty DIY videos vary in quality and thoroughness.) And if replacing an entire headlight housing requires removing parts like a bumper cover, you’ll probably also need access to slightly more sophisticated hand tools.

      The cost for new housings, including a new lens, ranges from expensive to very expensive. And yet a relatively inexpensive fix is still possible, particularly if you have a good salvage yard nearby where you can pick up used (way cheaper) parts. You can even practice your first removal procedure on the yard’s “you pick it” donor car.

      Most headlight bulbs are easy to replace; headlight housings require more work.

      After you’ve installed the replacement housing but before you reinstall any parts you’ve removed to get access to the headlamp unit, cycle the lights on and off to make sure that the high- and low-beam replacement bulbs and reattached wiring are fully functional. That will save you the time and frustration of discovering a loose connection or an incorrectly installed bulb too late, which will require removing and reinstalling the bumper cover or grille pieces. And, of course, the headlights will need to be aimed. For this we suggest taking the car to a repair shop; you could attempt to aim them out on the road, but this is a hit-0r-miss process at best. A shop has the expensive aiming gear to do the job right.

      DIY Tips

      • For working on your vehicle, choose a clean section of driveway or a workspace (like a garage) with good light. Be patient and allow yourself plenty of time (two hours minimum) for changing a headlight. It might be simple, but it could also be more complicated than you planned.
      • Place any retaining clips and fasteners that you’ve removed in a jar or can. They’re too easy to lose otherwise.
      • Use masking tape and a felt-tip pen to mark where the wiring came off, so it goes back on in the same way, meaning correctly.
      • An old throw rug, a rubber mat, or a large piece of clean cardboard to lie on can make kneeling or working under the car more comfortable.
      • Listen for a sharp click when connections are made.

      Heed these tips and we expect that your headlight replacement efforts will go well. And we hope that you don’t have as many bulbs to replace as this guy:

      How to fix a low beam headlight

      Most headlight systems are straightforward and include a few basic components like the bulbs, a relay, a fuse, and a switch. There are variations on this basic theme, like some vehicles have daytime running lights, adaptive headlights, or other little wrinkles like fog lights, but the idea is still the same. When you turn on your headlights, that switch activates a relay. That relay, in turn, actually provides the electrical connection between your headlight bulbs and the battery. Fuses are also involved in order to provide a sacrificial failure point to protect the rest of the wiring.

      If any of these components stop working properly, your headlights will fail. And by looking at the way they failed, you can usually backtrack to figure out the best place to start troubleshooting.

      When headlights stop working, it’s either an electrical problem or a physical issue with the bulbs themselves. In order to get to the bottom of the situation as quickly as possible, it’s important to make note of exactly what type of failure you have experienced. Based on which bulbs have stopped working, and under what circumstances, you can use the following information to narrow down a solution:

      One headlight doesn’t work

      This is usually caused by a burned out bulb. You can Replace the bulb. If it still doesn’t work, suspect a wiring or fuse problem.

      Neither of the headlights work

      It’s safe to say this is cause by either burned out bulbs, or an issue with power or ground. Check for power and ground, and fix if necessary. Otherwise, replace the bulbs. Bulbs usually don’t burn out together, but it’s still important to rule that out by checking for power. Most total headlight failures are caused by a bad component like a fuse, relay, or module. Wiring problems can also cause both headlights to stop working.

      High beam headlights don’t work or low beams don’t work

      A burned out bulb, or a problem with the high beam switch or relay can be the culprit here. You’ll need to replace the bulb, switch, or relay. If just one bulb fails to work in either high beam mode or low beam mode, it may be the bulb. Most headlight failures that are limited to just high or low beams are related to a relay or the high beam control switch.

      Headlights work but seem dim

      This could be an issue with foggy lenses, worn out bulbs, or a charging system issue. Clean the lenses, replace the bulbs, or repair the charging system. If your headlights always seem dim, the problem could be foggy lenses or worn out bulbs. If your headlights seem to dim during specific circumstances, there may be a charging system issue.

      Fixing a burned-out headlight is usually an easy job, but there are cases where you may want to bring your car straight to State Street Auto Repair. If you don’t own some basic tools and diagnostic equipment, like screwdrivers and a voltmeter, then you may want to think about bringing your car to a professional. We are here to help answer all your headlight questions and make sure your headlights are working properly, shining brightly, and keeping you safe!

      When low beam headlights don’t work the problem can be as simple as a blown fuse or as complicated as a bad body control module. I’ll walk you through the diagnostic steps to find out why your low beam headlights don’t work.

      Check for power at the low beam headlights connectors

      The low beam headlight connector is always the starting point for diagnosing headlight issues. Disconnect the electrical connector from the low beam headlight bulb. Then examine the condition of the connector. Look for melted plastic, corroded pins, or any sign of overheating.

      How to fix a low beam headlight

      Melted low beam headlight connectors

      If you find any indication of overheating, STOP and skip down to the testing portion of this article.

      Test for battery power

      If your vehicle has only one headlight bulb on each side of the vehicle, the bulb contains two filaments, one for the high beams and one for the low beams. The electrical connector will have three terminals: battery power for the low beam and high beam and a ground. With the headlight switch in the ON position for low beams, use a digital voltmeter to test for battery power. Connect the negative meter lead to the battery negative terminal or a good ground spot. Then use the positive meter probe to check for power in each of the terminals of the headlight connector. If you see full battery voltage of 12.2-volts or more on the low beam terminal, power is getting to the low beam headlight. Leave the positive meter lead attached to that terminal and move the negative lead to the ground terminal in the connector. You should read the same voltage. If you don’t get full battery voltage, you have an open in the ground connection. If you get a voltage reading but it’s not the same as when the negative meter lead was connected to the battery, then you have high resistance in the ground circuit. Follow the ground wire to it’s termination point and clean the ground connection and retest.

      If power isn’t getting to the low beam headlight

      Some vehicles have a separate fuse for the left and right low beam headlights. Refer to the fuse box diagrams in your owner’s manual and check the fuses. If they’re good, check to see if your vehicle uses low beam headlight relays. If so, swap the headlight relay with another relay in the fuse box with the same number. If that still doesn’t work, you’ll have to get a wiring diagram for your vehicle and find out which device switches power to the low beam headlight relay.

      In older vehicles, it’s usually the headlight switch. But in newer vehicles, it can be the generic electronic module (Ford), Body control module, Intelligent power module, front control module, etc.

      If the low beam headlight connector is melted

      How to fix a low beam headlight

      Working headlights are essential for driving any car safely, but they occasionally go out. Knowing how to change a headlight and what to look for when the front of your car goes dark can help you quickly remedy the problem.

      Check if the headlight bulb is out

      Determining the cause of a headlight issue begins simply by observing. First, put your headlights on to see if it’s just one light that’s out. If one is out, 90% of the time the light will go back on by simply replacing the bulb, says Emilio Zullo, owner and technician at E & L Automotive, in Ossining, N.Y. One quick test, if you don’t have a bulb handy or if you are out on the road when you notice the headlight issue, is to pull over and tap the light with your fist, which sometimes will make it go on, he says.

      “If it goes on, that means the filament is burnt out,” Zullo says. “When you hit it, you’re shaking the filament and, if this makes contact, it actually lights up.” This can at least enable you to make it to an area where you can have the light repaired, he adds.

      How to change a headlight bulb in 5 steps

      Check your owner’s manual for details on how to change the headlight in your specific vehicle, as well as what headlight bulb to purchase.

      Step 1. Power your car down

      To ensure safety, turn off your car and take the keys out of the ignition.

      Step 2. Open engine compartment

      Pop your car’s hood and locate the headlight holder, near the front of the car.

      Step 3. Disconnect the headlight bulb power wires

      There are usually three wires attached to the base of the lightbulb. Push down the clip or cap holding them in place.

      Step 4. Unscrew the old headlight

      Every car is different, Zullo cautions. “Some cars you can get right to the bulb, but with some cars you can’t,” he says. Sometimes the battery or the air filter housing is in the way and sometimes you have to take the inner fender out and get behind it.

      However, if you can open the headlight, it’s then just a matter of changing the halogen bulb. This means seeing how the bulb is locked in and carefully unlocking it. If you break the clips that are used here, though, you’ll need to take out the whole headlight, Zullo warns. “So you have to see how it’s hooked up, gently take it apart and then you have to reverse the procedure going back together without putting your fingers on the glass of the bulb,” he says.

      Step 5. Screw in the new headlight bulb

      Gently screw in the new bulb without touching the glass of the bulb; oil and dirt on your hands can cause the bulb to burst once it heats up. Close the hood of your car. With the new bulb in place, your headlights should once again be as good as new, and you can once again enjoy driving your car day or night.

      Most times, changing a headlight is straightforward and doesn’t require taking your car to a mechanic. Check out other DIY car maintenance projects anyone can do.

      If your replacement headlight bulb doesn’t work

      Ultimately, if you replace a bulb and that doesn’t work, then you have to test the fuses and the wiring. “If you have power going to the fuses and no power going to your light, you’re having a wiring problem,” Zullo says. “It could be that a wire broke somewhere, got pinched or something like that.”

      Another thing to consider if you recently changed a halogen bulb is whether the replacement bulb was appropriate for your plug. Zullo points out that halogen bulbs today run very hot, and some car parts stores sell brighter or colored replacements over the counter that are touted as better for visibility but that run even hotter. “So what happens with a stock OEM plug that the car came with from the factory is that it can’t handle this extra wattage,” he says. “It starts to melt, and then it makes a bad connection and your light goes out.” At that point you can’t even put a new bulb in, you have to change the whole light socket, Zullo says.

      What causes car headlights to go out?

      1. Old age

      The most common culprit for a burned-out light is age, says Zullo. “You could be driving and not notice that one of your headlights is out, and then, since the other one is the same age, within weeks that one might just go bad, too,” he says. Suddenly the problem becomes scarily apparent.

      2. Extreme cold and heat

      Besides age, extreme cold or heat can also cause headlights to burn out. The changes in temperature can impact the lightbulb filament, which is very delicate.

      3. Oxidation

      With newer halogen bulbs, another cause of dimming lights can be oxidation of the plastic housing, causing it to appear white or yellowish, Zullo says. This diminishes the beam of light that helps drivers to see the dark road ahead, he says. “In that case, you would have to replace the whole headlight assembly,” he adds.

      4. Cracks in bulb housing

      In addition, any cracks in the housing can cause halogen bulbs to burn out because these can’t take any moisture. “So you could put a new bulb in there and within a day or two it will blow out because of the humidity and the wetness,” Zullo says. “Also, these bulbs cannot be touched by your fingers; if you’re installing it, you have to use rubber gloves because if you put your finger on the bulb the salt from your sweat will burn that bulb right out.”

      Have a safety plan in case your headlight burns out while driving. Make sure to practice safe driving when you’re on the road.

      Are your headlights leaving you in the dark? Dim, dead, or fading headlights are both terrifying and dangerous for drivers. Without proper repairs, you could find yourself facing a variety of problems—from a failed annual car inspection to serious accidents on the road. The auto mechanics at Chapel Hill Tire are here with a comprehensive look at dim headlights and what you can do about them.

      Headlight Problem 1: Burnt Out Bulb

      The most common problem that faces headlights is dim, dying, or burnt-out bulbs. Thankfully, this also comes with the most simple solution: bulb replacement. Much like the lightbulbs in your home, headlight bulbs need to be replaced every once in a while.

      Headlight bulbs might need to be replaced more frequently if you tend to leave your headlights on during the day or if you regularly drive at night. For example, your bulbs might burn out more often if you drive for Uber, Lyft, or delivery jobs in the evenings. Older vehicles that have never had bulb replacements are also ticking time bombs for burnt-out headlights.

      How can you tell when you need new headlight bulbs? In addition to noticing your headlights looking dimmer than usual, you can check for a burnt-out bulb with a few simple steps. Simply park your vehicle in a safe space and turn on your headlights. Then, step out of your car and check to ensure that both headlights are bright and functioning. When you notice one or both lights starting to dim, bring your car in for a bulb replacement service.

      Headlight Problem 2: Lens Oxidation

      Some drivers are surprised to learn that headlight dimming is not always caused by burnt-out bulbs. In fact, the lenses themselves may be to blame. Headlight lenses—the plastic pieces that cover the bulbs—are often made out of acrylic. This material is known for chemically reacting with the sun’s UV rays. Over time, your lenses can become oxidized—leading to a foggy, cloudy, or yellowed lens appearance. The opaque shade caused by oxidation does not let as much light pass through as clear lenses. This will leave your headlights looking dim, even if you have brand-new bulbs.

      The solution here is simple: headlight restoration service. Using professional-grade tools and experience, your mechanic can address lens oxidation and help protect your headlights from future troubles. You can read our full guide to headlight restoration service here.

      Headlight Problem 3: Wiring Troubles

      Your headlight bulb is illuminated by an array of electrical components. In most vehicles, this includes a wiring harness and a fuse. These components provide the power needed to fuel your headlights. Wiring troubles can cause your headlights to dim, misfire, or stop working entirely. Wiring troubles are rare, but not unheard of. They also become more likely if you have tampered with your headlights recently or attempted any DIY repairs.

      This headlight repair will depend on the exact nature of your wiring troubles. You may need a wiring adjustment, a new wiring harness, a replacement fuse, or another electrical repair. An experienced mechanic can diagnose your headlight troubles and work with you to create a repair plan.

      Headlight Problem 4: LEDs vs. Incandescent Bulbs

      Have you ever driven past someone with blinding headlights? Even without the brights on, some LED headlights can seem much brighter than traditional versions. As such, if you are driving with traditional incandescent bulbs, you might begin to think your headlights seem dim in comparison.

      Why are LED headlights so bright? According to the U.S. Environmental Protection Agency and the U.S. Department of Energy, LED lights can appear brighter than incandescent bulbs without providing any extra light. Why? Traditional headlights have a softer, warmer, sometimes even yellowish hue. Meanwhile, LED lights emit a sharp white light with bluish tones. This color is harsher on the eyes, and it contrasts more starkly with the darkness of the night. As such, LED headlights can seem much brighter than incandescent bulbs—even when producing the same amount of light.

      Of course, the brightness of a headlight will depend on other factors, including the vehicle make/model, the headlight lenses, the headlight shape, and more. Overall, the jury is still out on the effects of LED headlights.

      • The pros: Some drivers favor the energy efficiency and longevity of LEDs. Others believe they may also provide more visibility on the road for drivers, even in cases where they do not produce extra light.
      • The cons: Those opposed to LED headlights suggest that they cause more harm than good by creating a glare for other drivers, which could cause accidents and eye strain.

      Regardless of your stance on LED bulbs, you can speak to your mechanic about alternative bulbs available for your vehicle if you are interested in brighter options.

      Headlight Problem 5: Setting Configuration

      Vehicles today often have several different lighting options for drivers to choose from. If you find that your headlights are too dim or have stopped working, take a moment to double-check your settings. Most new headlights adjust automatically unless they are otherwise configured. As such, many drivers “set it and forget it.” When an accidental bump or guest driver adjusts your lighting, you might not think to check the setting configuration.

      While it might seem obvious, there is a chance that you have your fog lights on instead of your standard headlights. In these cases, a simple adjustment of your headlight settings should get them working again.

      Whether you’re driving home from a late night at work or get caught in a rainstorm while taking the kids to school, you rely on your headlights to lead the way. When your headlights aren’t functioning properly, it not only means that you can’t see but it also means that other drivers can’t see you — compromising your safety and the safety of your passengers.

      If you’re having problems with your headlights, check out this handy troubleshooting guide. Be sure to consult your trusted mechanic for further assistance if you continue to have problems.

      Background info: Halogen headlight bulbs are a popular light source for automotive headlights as they are simple, cost effective, provide a bright light and generally have a useful lifetime of about 1,000 hours under normal conditions. If you drive 12,000 to 15,000 miles per year, you may replace a bulb every 5 or 6 years depending on how much night driving you do.

      Solution: Before replacing the bulb in the non-working headlight, check the electrical connector at the back of the headlight for any damage or looseness. The socket that holds the bulb in the headlight housing usually twist-locks into the back of the housing and a quarter-turn counterclockwise will enable you to pull the socket and the bulb out of the housing. Remove the bad bulb from the socket.

      Caution: Don’t touch the glass of the new halogen bulb with your fingers. The oil from your skin will react with the special quartz glass and will cause the bulb to heat unevenly, which may result in the bulb burning out prematurely. Handle the bulb by the socket using a cloth or while wearing gloves. After inserting the new bulb in the socket, test the bulb before replacing the socket in the headlight housing by turning on your lights. If the bulb works, replace the socket and you’re on your way.

      If the bulb does not light up, the problem could be a corroded socket or a wiring fault, which is a problem best addressed by your mechanic.

      Background info: High Intensity Discharge (HID) headlight bulbs are arc lamps, like a neon sign. Instead of heating a filament to produce light, electricity arcs between two electrodes inside the bulb. HIDs are more efficient than halogen lamps, making more light with less energy. HID headlights require a ballast to step up the voltage, so they also require a more complex electrical circuit with a high-voltage ignitor, which complicates the troubleshooting process just a bit.

      Solution: In some HID headlights, the bulb and the ignitor are one unit and both must be replaced. Check your owner’s manual to see if this is the type in your vehicle. If so, take a known good bulb/ignitor and put it in the socket from the burned out headlamp. If the bulb lights up, you know that the original bulb/ignitor is bad and must be replaced.

      Other applications of HID headlights use separate bulbs and ignitors, and it’s necessary to do a little more detective work to find out which one should be replaced. Repeat the process outlined above to determine if the bulb is the issue.

      If the “good” bulb doesn’t illuminate, you need to take a known “good” ignitor module and connect it with the socket from the burned-out headlight that now has the “good” bulb. If the bulb lights, then you know that all you need to buy is a new ignitor module. If the bulb still doesn’t light up, there is a fault in the wiring harness or a corroded bulb socket and it’s time to call your mechanic for expert assistance.

      Background info: Driving without headlights is extremely dangerous, reducing your ability to see at night or during inclement weather. If neither of your headlights work it’s time to do some detective work.

      Solution: If both headlights aren’t working, it’s unlikely that a bulb is at fault. The likely cause is a fuse, headlight relay, headlight switch, dimmer switch or a wiring fault. About the only cause that is an easy fix is a blown fuse. Consult your owner’s manual to locate the main fuse for the headlight circuit and replace that fuse with one having the same amp rating. If that doesn’t cure the problem, then it’s time to make an appointment with your favorite mechanic for some expert help.

      How to fix a low beam headlight

      Caspar Benson / Getty Images

      Required by law around the world, low beam and high beam headlights help you see and be seen, in all kinds of weather and at any hour of the day. Low beams are the bare minimum, for safety’s sake, but high beams are an absolute must for night driving over 25 mph. For most vehicles, headlights are a basic electrical system, controlled by switches and relays to turn them on and off. If your high beams stop working, here are nine of the most-common causes.

      Headlight bulbs are available in every autoparts store and many other stores, so it should be easy to find what you need. Check your owner’s manual to be sure which kind of high beam bulb you need and get familiar with the fuse box in case the high beams stop working. Finally, practice using a digital multimeter so you can rule out electrical problems before replacing other components.

      Blown Headlight Bulb

      ” data-caption=”A blown high beam headlight bulb, an easy fix.” data-expand=”300″ data-tracking-container=”true” />

      This is the most common cause of a single high beam headlight not working, but isn’t common if both high beams aren’t working, because it’s highly unlikely that both bulbs would blow at the same time. Headlight bulbs have a limited lifespan — 450 to 1,000 hours — so they’ll eventually burn out.

      Blown High Beam Fuse

      ” data-caption=”Fuses protect the wiring from circuit problems, such as short circuits.” data-expand=”300″ data-tracking-container=”true” />

      A fuse protects the wiring from damage, in case too much current is being drawn through the high beam circuit. The fuse will blow if there’s a short circuit, but it might also blow if an accessory is drawing off it or if the bulb is the incorrect wattage. Repeated blown fuses require more diagnosis to pinpoint excessive current.

      Faulty High Beam Relay

      ” data-caption=”Get familiar with the fuses and relays that control your headlights.” data-expand=”300″ data-tracking-container=”true” />

      The headlight switch usually doesn’t control the headlight bulbs directly, but through one or more relays. The headlight switch powers a relay, which powers the headlight bulb. This protects the headlight switch from the high current used by the high beam headlights.

      Failing HID Generator

      ” data-caption=”Always handle Xenon HID headlights with care.” data-expand=”300″ data-tracking-container=”true” />

      In the case of high-intensity discharge (HID) headlights, or Xenon headlights, there’s an additional component. To get the xenon and salts to plasma state, the HID generator bumps the voltage up to 30,000 V, then stabilizes around 90 V when the bulb is in operation. If the generator fails, the bulb won’t light.

      Wiring Problems

      ” data-caption=”Make sure to test for voltage at various points in the system.” data-expand=”300″ data-tracking-container=”true” />

      Sarote Pruksachat / Getty Images

      The most common short circuit is caused by damaged wiring, perhaps due to a crash, damaged connector, or poor aftermarket accessory installation practices. Broken wiring simply stops current flow, while chafed or damaged wiring might send it elsewhere, to ground or to another circuit. Loose or corroded connections, especially at the headlight bulb, can overheat and melt.

      Failing Headlight Switch

      ” data-caption=”Less common, a faulty headlight switch would stop high beams working.” data-expand=”300″ data-tracking-container=”true” />

      Alan D / Wikimedia Commons

      A failing headlight switch is uncommon, because the headlight switch is inside the vehicle and well-protected. Still, if you drive a lot, especially at night when you must constantly change between high beams and low beams, you might wear out the headlight switch.

      Headlight Fogging

      ” data-caption=”It doesn’t take long to restore fogged headlights and night visibility.” data-expand=”300″ data-tracking-container=”true” />

      If the high beams function but don’t seem to light your way, especially if you drive an older vehicle with polycarbonate headlight lenses, your car may be a victim of headlight fogging. This isn’t simply scuffing, but an actual chemical change from polycarbonate’s exposure to solar ultraviolet light and caustic exhaust emissions. The diffused light doesn’t project very well, making it hard to see, even when your high beams are on.

      Incorrect Headlight Bulb

      ” data-caption=”Make sure to use the right high beam bulb for your vehicle.” data-expand=”300″ data-tracking-container=”true” />

      Nicolas Loran / Getty Images

      On some vehicles, particularly those with HID headlights or solid-state circuit protection (Zener diodes or high beam circuit breakers) installing the wrong bulb might result in intermittent headlight operation or no high beams at all. The wrong bulb might not ignite at the right voltage or draw too much current for the circuit protection’s design.

      Dirty Fingers

      ” data-caption=”If possible, refrain from touching the glass while installing headlight bulbs.” data-expand=”300″ data-tracking-container=”true” />

      “Didn’t I just replace that high beam bulb?” you say as the high beams fail yet again. This can happen if greasy fingerprints cause part of the bulb to heat unevenly, breaking it. If you have multiple headlight bulb failures, make sure you are especially clean when doing the job. If at all possible, don’t touch the glass portion of the bulb at all. If necessary, handle the bulb with clean latex or nitrile gloves. Finally, if the bulb is dirty, clean it with a fresh alcohol pad before installation.

      You might have noticed while driving home in the evening that you have a defective headlight. The darker it gets, the worse your visibility becomes – which not only can be tiring for you as a driver, but it can also be dangerous for both you and other road users. You cannot always carry out repairing headlight lenses yourself; sometimes the only thing that helps is a trip to the workshop. However, with a little technical skill and some handyman talent, it is possible to do the following repairs yourself:

      • Replacing bulbs/light sources
      • Repairing loose headlamps

      But if you have the following problems, it is better to go to a workshop instead of doing it yourself:

      • repairing cracks in headlight or removing scratches from headlight covers
      • Defective xenon or LED headlights
      • Adjusting headlamp levelling

      Replacing light source

      How to fix a low beam headlight

      If the light on the front or rear of the car is broken, you might be able to repair this yourself. The prerequisite is that conventional bulbs are used in your headlamps and neither xenon light nor LED bulbs are used. The replacement or repair of the latter two light sources should only be carried out by specialist personnel as subsequently the headlamps have to be readjusted, a task requiring special measuring equipment.

      How to change the rear light or the low beam is described in your vehicle’s manual. There may be differences from model to model in the replacement of bulbs. On some vehicles you can access the low beam via the inside of the engine compartment, while on others you have to remove the headlamps to change the bulbs.

      Repairing loose headlamps

      How to fix a low beam headlight

      Sometimes it happens that a headlamp no longer has a tight fit. The most common cause is that the ventilation rubbers have been damaged by foreign bodies such as dirt, leaves or small twigs. If water then enters the headlamp, it can no longer drain off. Over time the headlamp becomes fogged up inside. In the worst case, water in the headlamp can also cause a short circuit.

      If the ventilation rubbers on the headlamp are damaged, you can very easily seal small cracks yourself with a little silicone. But before you do this, check that the headlamp is absolutely dry inside. It is best to use a hair dryer to ensure the area is completely dry before applying the silicone.

      Another possibility for water in the headlamp is cracks or fissures in the plastic cover. These can be caused either by stone chippings or a light source with too high an energy intensity that makes the plastic crack through excessive heat generation. In this case, you should replace the headlamp or rather the plastic cover (or have it replaced) and install a less energy-intensive light source.

      Removing scratches from headlight lenses

      Repairing cracked headlight plastic by polishing is illegal because as a result headlamps are structurally changed. In order to fix cracked scratched headlamps, the covers need to be exchanged and replaced with new ones.

      Repairing xenon or LED headlamps

      Repairing LED headlamps is really not possible since the complete headlamp must always be replaced as individual components in it cannot be repaired separately.

      How to fix a low beam headlight

      Xenon lamps cannot be replaced without a great deal of work and effort either, which is why you should go to a workshop for such repairs. To replace xenon lamps, the complete headlamp has to be removed and often the battery also has to be disconnected. After replacing xenon lamps, the headlamp also has to be readjusted.

      Readjusting headlamps

      If the automatic headlamp levelling system of a xenon headlamp is defective, the most common cause is a broken actuator of the individual headlamps. If, for example, you notice that the road is no longer properly illuminated, that you dazzle oncoming traffic while driving, or that a headlamp does not move when you start the engine, it is best to go to a workshop.

      Do not wait too long before repairs are carried out, even if you yourself are hardly affected by the headlamp levelling status. Because if you wait too long, you might endanger other road users.

      Need to adjust your beams? Here’s out quick-and-dirty guide to ensuring your headlights are aligned to shine on the road rather than in the eyes of oncoming drivers.

      How to fix a low beam headlight

      It’s important to have quality headlights to light your path. However, those bulbs aren’t doing any good if they’re not correctly aimed at the road, and that’s something many owners forget or downright neglect when owning a car.

      Time or merely replacing the bulb can cause a car’s headlights to become misaligned. This could lead to reduced visibility, which is a huge problem when driving at night. When you’re traveling at 60 mph, you have only seconds to avoid a collision if something darts into the road. Misaligned lights can reduce your reaction time to zero.

      Making Some Adjustments

      Adjusting headlights is an easy though often tedious task that takes time to get right, and every car is different. With practice and patience, you can learn to do it in your driveway in a matter of minutes.

      Start by checking whether your car has built-in bubble levels meant to help you align the headlights. Honda, for example, offers vertical and horizontal bubble levels that make it easy to tell if your headlight aim is off. They’re often located on the top and side of the headlight unit. With these, you can tweak the aim, until the bubble is centered in the level. Some makes and models offer only vertical or horizontal bubble levels while most others provide no visible alignment indicator at all.

      Misaligned lights can reduce reaction time to zero.

      If your car lacks such a convenience, don’t worry. There’s a surefire do-it-yourself way to check your headlight alignment and get your lights back into shape.

      First, park on flat ground and make sure your car is level. That means unloading heavy cargo, filling the gas tank to full and making sure tire pressure is correct at all four corners. You can’t align headlights if your car isn’t level. Make sure your suspension is in working order and isn’t causing your car to point up or down at any one side, too.

      Next, find a plain wall. Pull the car as close to the wall as possible and turn on your lights. This way, you’ll find the centers of the low-beam headlights. Mark both spots with a single piece of horizontal tape running through the middle. Make the vertical tape marker about two feet long, again running through the center of the low-beams.

      After that, find the headlight adjusters. Each make and model is different, but generally, the adjusters are a type of screw or bolt on the back or side of the headlight unit. While they’re not often marked, they tend to be gray or silver, which stands out from the black headlight housing.

      However, some vertical adjusters are located on the bottom of the unit, as is the case with several GM vehicles. This makes access difficult. Sometimes automakers cut a hole in the vehicle’s metal structure that allows access to the adjusters. A look at the owner’s manual or a quick Google search can help.

      Lining Things Up

      After you find the adjusters, back up the vehicle until it’s 25 feet from the wall. We recommend that you measure this out so the distance is accurate. This is a general distance guideline, as some manufacturers use different distances for headlight alignment. Chrysler recommends aligning headlights at 33 feet while Toyota says 10 feet. Here’s another instance where the owner’s manual comes in handy.

      Once you’ve backed up, block one headlight and look at where the other beam falls compared to the markings you made on the wall. For vertical aim, the top of the most intense part of the beam should be at or below the centerline of your horizontal tapeline.

      For horizontal aim, the most intense part of the beam should be to the right of the vertical tapeline. This is so you don’t blind oncoming traffic and so you can see the side of the road and any people, animals or things that might pop out into your path. Make adjustments as necessary if the aim is off by turning the adjusters a quarter of a turn at a time to see where the new alignment falls. Do the same procedure for the other headlight.

      Good news! Adjusting your low beams will also reset your high beams to where they should be, as most cars don’t have a separate adjustment for the high beams.

      Some states and countries have their own specifications when it comes to aiming headlights, so it’s best to follow those rules when aligning yours. Many automakers offer specific headlight aiming specs, too. For example, General Motors says there should be zero distance between the center of the beam and the horizontal centerline of the headlamp, while Toyota says a 1/2 inch is within spec. Chrysler allows two to six inches below centerline while Nissan allows for slightly more than 3 1/2 inches.

      If you follow these instructions, you’ll have a better chance at dodging wayward deer on the roads—and other drivers will appreciate your hard work.

      Vehicle: 2003 Mercedes Benz E320 Sedan (211.065), V6-3.2L, Automatic Transmission

      Mileage: 262,396

      Problem: The high and low beam headlights were out on the passenger side. Because of the vehicle’s age, the owner decided to replace all four headlights. Unfortunately, the passenger side high and low beams were still inoperative. He brought the car to the shop for a diagnosis and repair.

      Details: The technician connected a scan tool, which revealed no diagnostic trouble codes. Next, the technician verified that there was no battery power to the passenger low and high beam headlights. At that point, he called ALLDATA Tech-Assist for advice.

      How to fix a low beam headlight

      The Tech-Assist consultant suggested starting by inspecting fuse #75 (40a), which is in the front pre-fuse box, mounted in the passenger footwell. Since the fuse checked out good, the consultant suggested verifying that the passenger signal actuation module (SAM) control unit was getting full battery voltage on terminal #5 (red) and that terminal #1 (brown) was getting a solid ground at connector I1. Both power and ground checked out perfectly.

      The next test was to check terminal #6 (yellow) for battery voltage on low beam and terminal #2 (white/yellow) for battery voltage on the high beam at connector I3.

      While testing those wires, the technician noticed that if he removed the SAM control unit bracket, the lights would work and when he tightened it back down, the headlights would lose power.

      How to fix a low beam headlight

      Upon closer inspection, he found the yellow and the white/yellow wires were both open under the floor panel. The SAM control unit harness was a little short and was being stretched, which caused the wires to break inside the insulation.

      Confirmed Repair: The technician repaired both wires and rerouted the harness so there wouldn’t be any tension on it. After the repairs, both passenger headlights operated normally.

      How to fix a low beam headlight

      The headlight on the passenger side would not work after replacing the light bulb. We checked the fuse for the headlights, and they had not blown.

      We had this problem on an Oldsmobile, but this issue may affect other makes and models.


      • The low beam on one side not working


      • Damaged wire harness inside the headlight assembly


      One possible solution is to replace the complete headlight. Replacing the headlight can be expensive.

      In this case, we decided to replace just the damaged wires and the connector. Since the bulb was a 9006 type, we purchased a connector for 9006 light bulbs online.

      Here is how we fixed it:

    • Turn on the lights and make sure the headlight is working.
    • Conclusion

      If your headlight doesn’t work after replacing the light bulb and checking the fuses, make sure to inspect the wires inside the headlight.

      For the safety of you and other road users, it’s important to have working lights on our cars. This includes side- and taillights, headlights (main and dipped beams), direction indicators, stop lights, a rear number-plate light, reversing lights, fog lights (front and rear), daytime running lights (DRL) , long-range driving lights and hazard warning lights.

      But how can you tell if your car lights are working and are your headlights correctly aligned?

      How to check if your car bulbs are working

      It’s possible to spot a broken bulb due to a light not working when turned on or if you spot a visible break in the filament, sometimes with blackened glass. In either case, it’s a good idea to test your bulbs with a test bulb kit.

      How to check if your headlights and taillights are working

      The easiest way to check if your lights are working is to turn the engine on and leave the handbrake on. Then turn on each light and walk around the car to visually check them.

      How to check headlight alignment

      We all know how annoying – and potentially dangerous – it is to be dazzled by the glare of oncoming headlights. But how can you check that you’re not blinding other drivers with your headlights?

      Checking the alignment of your headlights isn’t difficult, but you do need some specific tools: a Phillips-head screwdriver, masking tape, a spirit level, a measuring tape, level ground, a dark wall or garage door and 10m of space.

      While you could check your owners’ manual for the precise distance required to check your headlight alignment (different manufacturers have different recommendations), it isn’t necessary to have a standard distance – as long as you measure correctly. In other words, the centre point of your headlights should be one cm lower for every metre your car is moved from the starting point. In other words, if the centre point of your headlights is 40cm from the ground when your car is 50cm from the wall, then the centre point should be at 35cm when your car is 5.5m from the wall. If this isn’t the case, the headlights need to be adjusted so the centre point is at 35cm.

      How to fix a low beam headlight


      Before you measure the centre point, it’s important to ensure your car is prepared correctly. This means:

      1. Park on level ground, 50cm from a dark wall or a garage door, with the front of the car facing the wall. Confirm your car is on level ground by using a spirit level on the side of the vehicle, for example on the doorframe or roof.
      2. Level your car by removing any excess weight from your boot and ensuring the tyre pressure in all tyres is at the manufacturer’s recommended PSI levels (check your owner’s manuals for this). If you have headlight aim adjustment wheel, move it to the zero position. And, if possible, ask someone to sit in the drivers’ seat, clean your windscreen and make sure that the fuel tank is half full.
      3. Measure the distance from the ground to the headlights to ensure the suspension is level.
      4. Check the inclination value on the headlight. It’s usually on the shell of the reflector. 1% means the low beam tilts 10cm for every 10m, and 1.2% means the low beam tilts 12cm for every 10m.

      How to fix a low beam headlight


      1. Place your car 50cm from the dark wall or garage door, then turn your main lights on (not your high beams or fog lights).
      2. Mark the horizontal part of the cut-off line (the red line in the image below).
        How to fix a low beam headlight
      3. Mark a horizontal line 10cm under the cut-off line (or 12cm if your inclination value is 1.2%).
      4. Move your car exactly 10m back and turn your headlights on again. Does the light from your headlights line up to the lower horizontal marked line? If not, your headlights need to be adjusted using the two alignment screws on each reflector until it lines up correctly.
        Please note: the alignment screws on each reflector can change both the horizontal and vertical alignment of your headlights. If you’re not sure you’ve correctly adjusted your alignment, talk to a trained technician.
      5. When you’re happy with the alignment of your headlights, it’s time to test it. Take your car out for a test drive, preferably along some darker roads, to check that your headlights are aligned correctly.

      Keep in mind that, even if you are happy with the horizontal alignment of your headlights, next time you visit a workshop, you should ask a mechanic with lighting expertise to make sure both the horizontal and the vertical alignment of your lights is correct.

      How to replace a headlight?

      There are a few reasons why a motorist might find that they need to arrange for their headlight replacement. The first reason is a blow out. Like a light bulb in your home, your headlight bulb has a limited lifespan and will, one day, need to be replaced. Some vehicle makes will use LED headlights or halogen headlights to help retain energy efficiency and ensure that the headlight assembly has a long lifespan. Regardless of the type of bulb, there will be a headlight assembly replacement available.

      These components of your vehicle are relatively straight forward to replace and generally it won’t take your mechanic long to complete a headlight switch replacement.

      If your vehicle has sustained damage and requires a headlight socket replacement, then your mobile mechanic from Lube Mobile can also ensure that you receive the best replacement headlights, that your new assembly is installed quickly and affordably, and that your new headlights are in working order, ready to head back out onto the road.

      Before the mechanic begins work on the headlight assembly, they will check all of the lights in your vehicle to ensure that there aren’t any other failing bulbs. They will check your brake lights, indicators (blinkers), reverse lights, fog lights and tail lights. Generally speaking, if a bulb has failed in your headlights then the second bulb won’t be too far away from failing as well. It’s a good idea to consider switching out both headlights in this case. This will ultimately save you money further down the track as you won’t be paying for a separate service and your full headlight replacement can be taken care of in a single service setting.

      You may also discover that your regular logbook service returns details of failing or failed lights and this may be the reason why you need headlight replacement. Other common issues also include fogging of the headlight lens. The lens is the clear plastic cover that protects the headlights and also helps to reduce things like drag in your vehicle design. The lens should be completely transparent to ensure that when the headlights are in use, they are shining brightly over the road ahead. UV damage to headlight lenses is very common and can be either reversed with treatment or you can opt to replace the headlight lens entirely to address the issue. This kind of deterioration is common in older cars and is a sign of the aging vehicle. It’s not, however, terminal by any case and relatively inexpensive to fix.

      As part of our standard service on all repairs and services, from steering to cooling systems and brakes to auto electrical issues like a starter motor, your Lube Mobile mechanic will undertake a thorough assessment of your vehicle and report anything that seems amiss or requires attention.

      How much is it to replace a headlight bulb?

      The cost for headlight replacement will vary depending on exactly what needs to be replaced and the kind of vehicle make and model you are replacing the headlights for. If it’s a high beam bulb replacement or a headlight lens replacement then prices can start as low as $25.00 and range over $100.00. Halogen bulbs typically cost around $20.00 for the unit but then there is labour to be charged on top for the mechanic’s time in removing the headlight assembly, successfully replacing the globe and then replacing the assembly. This may also be affected if the car has sustained any damage and that damage makes it difficult to access the area properly.

      The headlights are a critically important party of your car and something that should always be in perfect working condition. Unless you’re good at driving by feel alone, your headlights are what allows you to drive safely at night.

      What is a Headlight Bulb?

      The world of headlights has changed dramatically over the last few decades. Historically, “classic” filament bulbs were the norm, however, newer cars nowadays have stepped up into LED and even “High Intensity Discharge” (HID) lights. While they perform significantly better, improving the safety and visibility of your vehicle on the road, these new bulbs are often more difficult and expensive to replace.

      Note, some vehicles have up to four bulbs (2x high beam and 2x low beam, left and right).

      How to fix a low beam headlight

      Why do you need a headlight bulb?

      Much like indicator bulbs and brake lights, they show other motorists where you are and what you’re doing. They also have the added benefit of showing you the road ahead when in poor lighting conditions.

      How do you know when it is time to replace your headlight bulb?

      If the headlight isn’t already out, you may notice it flickering or not shining as brightly as before. The headlight bulbs may falter at different times, making it easier to see one starting to fail. In NZ, headlights are checked for their LUX output during your WOF, and this is a common failure point to consider.

      What happens during a headlight bulb replacement?

      While headlight replacements are not that complicated, in some cases the front bumper may need to be removed to gain access. The mechanic or auto electrician will first check that a fuse hasn’t blown, before replacing the bulb(s) and checking its operating properly.

      How much does a headlight bulb replacement cost?

      The cost of replacement can vary greatly depending on the type of bulb. On top of this, there are often multiple bulbs requiring replacement. The cost for this ranges, and starts from around $75.

      Is driving with a broken headlight bulb unsafe?

      Absolutely. Without working headlights you will be unable to see or be seen in the dark, and lights with diminished performance are dangerous as well. On top of this, it is illegal in NZ to drive with broken headlights.

      Not shining so bright…

      Driving home late one night, you notice that one of your headlights is burned out. “Funny,” you think to yourself, “I just replaced that bulb not too long ago.” This is obviously a concern, as driving at night or in inclement weather with just one headlight is dangerous.

      Constantly replacing headlight bulbs is not only a hassle but also an indication that there could be an underlying problem with your vehicle. Read on to learn some causes of premature headlight bulb burn out.

      How to fix a low beam headlight


      How to fix a low beam headlight

      Halogen bulbs and sealed beam headlights have very fine tungsten wire filaments inside that emit light when heated. Even under ideal conditions, the filament can break, leaving you in the dark. Vibration caused by driving over rough roads, potholes and bumps will reduce the filament lifespan.

      Other causes of vibration may be due to a fault in your headlight structure. If the bulb is not securely mounted in the headlight assembly, it will vibrate, even under normal driving conditions. Insecure mounting may be the result of a bent bulb socket or headlight housing.

      Similarly, if the headlight housing is not securely attached to your car, the entire housing, including the bulb and filament, will vibrate while you are driving, shortening the filament lifespan. Vibration of the headlight housing may occur even if it is tightly attached to your car if one or both of the front wheels are out of balance. If you feel a shimmy in your steering wheel, this could be a contributing cause of successive bulb failures.

      This blog post is for 2014+ Toyota Corollas

      If you drive a Toyota Corolla that’s 2014 or newer, you probably know your Corolla comes with LED headlamps as standard equipment.

      More efficient, durable, and generally lasting 10x longer than halogen, LED headlamps are becoming the headlights of choice for car manufactures.

      You also probably want to know if the LED headlamp bulb breaks, can you easily replace it?

      I’ve got bad news and good news.

      The bad news is, no, you cannot replace the LED headlamp bulbs in your newer Toyota Corolla because the low-beam headlights do not use a bulb at all. Instead, newer Corollas utilize Light Emitting Diodes (LEDs) mounted on a chip, projected through a lens, and sealed in a headlight low beam module.

      Here’s what I mean. As you can see, it’s not possible to replace individual LEDs like you would be swapping in a new bulb. There are multiple LEDs soldered to a chip.

      Check out this video by Youtuber GTFGrill that shows a disassembled headlight unit for a 2014-2016 Toyota Corolla. The 2017-2019, and 2020+ Corolla headlamp units have a similar construction.

      Notice how the low-beam headlamp module is one sealed unit. Here are screenshots showing what I mean highlighted in green.

      And here’s what your owner’s manual says on the subject.

      If, for whatever reason, the low beam headlight module is damaged due to extreme operating conditions or a projectile, like a rock flung off a semi, destroys it, you’ll have to replace the entire headlight assembly.

      LED Headlight assemblies for the Toyota Corolla from third-party manufacturers roughly cost $150 for 2014-2018 Corollas and $350 for 2019+ Corollas. Keep in mind, that’s just for one left or right headlamp assembly. As time goes on, LED headlamp assembly units should become cheaper.

      Here are screenshots of what you can expect to pay from Rock Auto for 2014-2016 to 2020+ Corollas, respectively. Prices for a 2016 Corolla headlamp assembly range between $150-$230 Prices for a 2020 Corolla headlamp assembly range between $350-500

      You can find cheaper Corolla headlamp assemblies for new, for as low as $100 on eBay.

      You can always also search for used headlamp assemblies. A quick search brought up used Corolla headlamp assemblies as cheap as $55. But, you run the risk of buying one with a malfunctioning LED headlamp module. Be sure to check the description, confirming a 100 percent functioning unit.

      It’s worth mentioning eBay is the wild west of aftermarket parts and, for new parts, suppliers are not as well vetted as Rock Auto does.

      The good news is LEDs are typically rated to last as long as 50,000 operating hours. Toyota ensured that whatever LED low beam module they equipped in your car, it would be durable and robust enough to last for the life of the car and then some.

      Barring nothing ever destroys your headlight, you’ll never have to worry about replacing your low beam headlamp modules.

      As for upgrading, while it’s technically possible to upgrade the LED module with an aftermarket LED unit, you probably shouldn’t. The LED headlamp module made for your Toyota is specifically engineered for your Corolla and its headlamp assembly. Equipping your Corolla’s headlamp assembly with an LED module with different specs may lead to inferior light performance compared to stock.

      While your Corollas has more expensive low beam LED headlamp modules, over the life of your car, they should essentially be trouble free, a maintenance item you never have to worry about.

      How to fix a low beam headlight

      Back in April of 2019, news broke that some 2010 – 2015 Cadillac SRX customers would be reimbursed for expenses incurred for repairs for their vehicle’s headlights. Now, almost a year later, some SRX customers are still complaining about issues with their headlights.

      Cadillac Society has received a number of emails and letters about this issue from concerned customers detailing the problems they’ve encountered with their Cadillac SRX headlights. To note, these emails and letters are recent, providing further evidence that the issue is far from resolved.

      How to fix a low beam headlight

      Some customers have sent emails to Cadillac’s parent company, General Motors, about the issue, but never received a response. Others indicated they couldn’t drive their vehicle at night, and that the vehicle warranty wouldn’t cover a fix. Still others say they had the headlights replaced for thousands of dollars without reimbursement. Finally, one customer said that driving the vehicle has become so dangerous, they have instructed their family to sue Cadillac for wrongful death if the vehicle’s poor lighting results in a fatal accident.

      Last year, it was reported that owners of 2010 through 2015 model year Cadillac SRX crossovers would be receive reimbursement for repairs addressing the faulty headlight issue, following a class action lawsuit filed in 2017. The class action suit is separate from another class action suit concerning the SRX headlights filed in Detroit in 2019.

      How to fix a low beam headlight

      The problem stems from allegedly faulty weather seals around the headlight that could prematurely erode, allowing moisture to enter the headlight casing and resulting in the headlight bulb to either dim, or burn out completely.

      Some customers have reported that the problem can return even after a repair is performed at a dealer, and some dealers have flat-out refused to fix the issue, even though the vehicle still under warranty.

      Reports from April of 2019 indicate that GM agreed to reimburse out-of-pocket repair expenses associated with the moisture issue at a rate of up to $1,600 per replacement. However, the class action lawsuits claim the fix doesn’t stop moisture from reentering the casing, causing the dimming issue to return. The Detroit lawsuit even claims that GM actively attempted to cover up the Cadillac SRX headlight defect.

      Hold on a Minute

      Most of us with vehicle ownership experience will know that changing light bulbs on a vehicle should be as easy as just removing the cover from the back of the light, and slotting a new one straight in; easy peasy, right? Unfortunately not, some vehicles can become your nemesis when it comes to bulb changes. Who would have thought that a very few specially selected vehicle designers have a unique ambition in life to make headlight bulb changes one of the most frustrating, time-consuming, expensive, hand-torturing maintenance processes there possibly is to do on a car?

      The point is proven when last week you spent most of Sunday morning just removing the front bumper and 100,000 of those dreaded, rusty bottom engine cover bolts just to swap out some pesky little light bulbs!

      Reason #1 – Faulty Voltage / Alternator Regulator (A.K.A Voltage Stabiliser)

      The voltage regulator is a critical piece of electrical equipment in a vehicle, they can usually be found attached to the side of the alternator or mounted separately. In easy-to-understand terms, it limits the maximum amount of voltage that runs through the electrical system to a safe and usable amount for all components to utilise.

      If the voltage regulator is intermittently having problems then it’s most definitely the source of your bulb problems. This is due to spikes of high voltage jumping through the system which in turn blow the bulb filaments and/or headlight fuses.

      You can perform a simple test to check if the voltage regulator is faulty, however you’ll need another person to help you rev the engine whilst you take a multimeter reading.

      • Acquire a multimeter if you don’t have one, you can usually purchase one for under £10
      • Open the bonnet and remove the positive red terminal safety cover from the battery (if there is one)
      • Set your multimeter to 20 DC volts as shown in the photo. The DC Volts symbol is a V, and next to it there should be three dots with a straight line on top
      • Don’t use the symbol with a V and a squiggly line next to it, as that’s AC volts. Useful tip – think of the squiggly line as alternating current (AC) to remember this!
      • Before you begin testing, make sure the ignition and all of your vehicle’s lights are off.
      • Connect the red + (positive) multimeter test lead to your battery’s positive terminal.
      • Then, connect the black – (negative) multimeter test lead to your battery’s negative terminal.
      • Have your assistant turn on the engine (check it’s in neutral first)
      • The multimeter reading should rise to around 13.8 volts whilst the car is idling, this means the alternator is charging the battery correctly
      • Ask the person helping to slowly rev the engine until it reaches 1500 – 2000 RPM
      • Check the multimeter reading and jot it down, the voltage regulator should cap the amount to 14.5v. If the reading is over 14.5v then your voltage regulator is most definitely faulty.

      Another known problem in the same category is that some poorly manufactured alternator belts can cause power surges due to static build up. This problem can be found by performing the check above and hopefully fixed by replacing the alternator belt with a premium brand, or by installing resistors to the low and high beam circuits. This is a common ‘online forum’ notable fix for some vehicles. Try replacing the regulator first to see if it fixes the problem.

      Reason #2 – Loose wiring connections to the bulb holder/bulb

      This can cause the current or ‘flow’ of electricity to contact intermittently on and off, this can in turn, cause an increase in heat. Temperatures that go beyond what the bulb is designed to cater for will easily cause the filament inside to blow.

      Vibrations in the headlight can also increase this problem, so check to make sure all headlight bolts are tight, that no headlight mounts are cracked and that the electrical connectors to the bulbs are secure. We recommend fitting new connectors to the bulb to completely eradicate them as the source of problems, especially if they look burnt, melted or show signs of corrosion inside.

      Reason #3 – Poor Quality Bulbs

      This one might sound like a bit of a cliche, however the truth is that dirt cheap bulbs are nowhere near the quality standards of high-end brands and this is why we will never sell them. The wire filaments are usually made from a far thinner gauge of tungsten which can see them fail in a matter of hours. Vibrations are the most common cause of failure on cheap bulbs, and this combined with thin gauge wire results in easy failures, especially if there are voltage fluctuations going on with a dodgy regulator. It’s an obvious sign of household technology put into a car bulb, so failures are bound to happen easily, have you ever seen the wire wobble around inside a household bulb? Stick to a high-quality German brand such as OSRAM, they’re available in our shop.

      Reason #4 – Touching the glass of the bulb on installation

      Halogen bulbs obviously get very hot during operation and the chances are that by the time you get to the stage of actually fitting the bulb, your hands look like this. Bulbs need to heat evenly throughout the whole of the bulb’s surface for an optimum lifetime, leaving traces of dirt and grime or even the oil from your skin can sometimes cause uneven heating when the bulb is in use.

      Touching bulbs with hands this oily is a recipe for premature failure

      In some extreme cases, dirt on the glass of the bulb can cause a complete structural failure and they end up exploding! Use clean latex gloves and only try to touch the bulbs metal base when installing, this can be very tricky when sometimes they’re hard to position correctly with limited amounts of space.

      Reason #5 – Excessive vibration

      Reason #6 – Excessive condensation in the headlight

      Too much condensation in headlights can cause electrical shorts and diminish the lifetime of bulbs rapidly, so it’s important to check if they’re getting too damp inside.

      Headlights are usually ventilated through the top and bottom of the unit through small holes or tubes usually found with a 90-degree bend to them. They’re designed to only allow a certain amount of air to flow in and out for heat dissipation but also to help reduce moisture in the lens. If the bulb covers on the back of the headlight aren’t mounted correctly or any seals have broken around the lens, then you can expect a higher amount of condensation in the headlight than normal.

      Aftermarket Headlights & Condensation

      Some after-market ‘copy’ headlights are made so poorly that a large amount of condensation can be seen after just a couple of weeks. It’s worth noting that minor condensation is perfectly normal, however when ‘pools’ of water form at the bottom corners it should be checked out ASAP. The staff here have their own experiences with aftermarket headlights and can safely say they’re a waste of time. For this reason among others, we only sell original (OEM) branded headlights due to wanting the very best for our customers.

      This page identifies and explains everything you need to know about Dipped Beam Headlights on your vehicle.

      What Are Dipped Beam Headlights?

      How to fix a low beam headlight

      Dipped beam headlights are located at the front of the vehicle and are designed for increased visibility when driving at night time.

      They are located next to your main beam headlights and sidelights and the dipped beam bulbs can be Halogen, LED or OE Xenon – depending on your vehicle.

      Dipped beam bulbs are pointed down towards the road to prevent other road users from being dazzled.

      Dipped beam is also commonly known as low beam throughout the UK.

      When To Use Your Dipped Beams

      The highway code states that you must “use dipped headlights, or dim-dip if fitted, at night in built-up areas and in dull daytime weather, to ensure that you can be seen“.

      You should always activate your dipped beam when visibility is low, it’s darker than normal, it’s raining heavily or foggy. Some of these aren’t required by law but commonsense should prevail which will prevent you from being in an accident. If you’re more visible on the road then there is less chance of someone not seeing you, making it safer for everyone.

      Your dipped beam headlights will have a lower light output than your main beam headlights to prevent “dazzling” other drivers.

      What Type Of Dipped Beam Headlight Bulbs Are Available?

      This completely depends on what bulb application your vehicle was designed for.

      You should check out our car bulb finder to see what dipped beam bulbs fit your car. We previously wrote a detailed car bulb guide a while ago which will show you exactly how to find the best bulbs for your vehicle.

      Honda Accord Headlight Bulbs Replacement Guide
      Pictures illustrated instructions for how to replace the light bulbs in a 2008 to 2010 Honda Accord sedan headlight assembly.

      Owners of other eighth generation Honda Accord coupe or sedan vehicles from 2008, 2009, 2010, 2011 & 2012 should also find the guide to be useful.

      Other Honda vehicles such as the Civic, Element, Insight, Pilot, Fit, CR-V, Ridgeline, and Odyssey may have similar headlight bulb replacement procedures.

      Removing the third one located a few inches closer to the center line of the car makes pulling back the fender well cover a lot easier.

      Once you pull back the fender well cover, you will be able to see the low beam headlight bulb power connector and socket base.

      Then remove the power connector by pressing on the plastic tab at the bottom of the connector near the wires.

      Try wiggling if it won’t come off easily.

      Then turn the socket 1/4 turn counter clockwise and pull it straight out from the headlight assembly.

      Remove the socket by turning it 1/4 turn counter clockwise.

      I had to use a pair of needle nose pliers to help turn the socket.

      Once the three black plastic pop rivets are removed, pull back the fender well cover and locate the low beam headlight bulb socket.

      Then turn the bulb’s base 1/4 turn counter-clockwise and pull it straight out from the socket.

      To remove the # 7528 turn signal / parking light bulb from the socket, push down on the bulb and twist it 1/4 turn counter clockwise until it can be easily lifted out of the socket.

      Replace it with a new # 7528 light bulb and test it by turning on the vehicle’s hazard lights. If it doesn’t flash as it should, try removing it and re-seating it back into the socket.

      5. Passenger Side High Beam Headlight Bulb – The passenger side high beam headlight bulb is located next to the passenger side turn signal / parking light bulb further towards the outside of the vehicle.

      Push on the the tab located near the bottom of the high beam headlight bulb power connector and wiggle off the connector from the bulb’s base.

      Then turn the bulb’s base 1/4 turn counter clockwise and pull the high beam bulb straight out from the headlight assembly.

      Replace it with a new # 9005 high beam headlight bulb and test it by turning on the high beams.

      It is located just in front of the driver side edge of the car’s battery.

      Just look first with a flashlight to orientate yourself and then reach in to grasp the turn signal bulb’s grey plastic base.

      Turn it 1/4 turn counter clockwise and pull it straight out from the headlight assembly.

      Removing the car’s battery helps make the job a lot easier, but is not necessary.

      Locate the light blue power connector on the high beam headlight bulb’s base situated just to the right of the turn signal bulb.

      Then push on the power connector’s retaining tab at the bottom of the connector near the wires and wiggle it until it comes free from the high beam bulb’s base.

      Then turn the high beam bulb’s base 1/4 turn counter clockwise and pull it straight out from the headlight assembly.

      Replace it with a new # 9005 high beam bulb and be sure to not touch the glass part of the bulb with your bare fingers.

      It’s easy to overlook the importance of your vehicle’s headlights during a bright summer afternoon, but just like the lights in your home, your vehicle’s headlights need to be replaced on a regular basis to function effectively. Driving without properly functioning headlights at night or in conditions with low visibility can be a danger to yourself and others on the road. To keep your headlights bright and ensure a safe drive, here are some of the warning signs you should be watching for to know if your vehicle needs a new set of headlight bulbs.

      Dim Headlights

      If you notice that the light coming from your headlights is dimmer than usual, there are two possible reasons. The first depends on how often you clean your vehicle. It’s possible for your vehicle’s headlight covers to develop a layer of buildup or grime that can decrease their overall effectiveness. If you noticed that your headlights have dimmed, make sure to thoroughly clean your vehicle’s headlight area and check if the light quality increases.

      If the dimness persists after a thorough cleanse, the problem may be that your bulb is nearing the end of its service life. In this situation, you should begin searching for replacement headlight bulbs.

      Flickering Headlights

      If your vehicle’s headlights are flickering on and off, it can be a very serious danger and should be addressed immediately. Flickering can be a sign that the filament of the headlight bulb has become damaged or excessively worn, just like a light in your home may flicker toward the end of its life. This can be a sign that the bulb is very close to burning out entirely.

      Flickering can also indicate that your vehicle’s headlight bulbs have a faulty connection. No matter what the cause, finding a replacement or fixing the connection before your headlights go out for good is essential for safe driving.

      Single Headlight Out

      Having a single headlight bulb burn out can sometimes be difficult to notice, but it is a major warning sign that your vehicle’s headlights are at the end of their useful lives. Since headlights are most often replaced in pairs, once one headlight goes out, it’s likely that the other has already begun to dim and could burn out soon as well. If one of your headlight bulbs has burnt out, you should look for a replacement pair as soon as possible.

      Types of Headlight Bulbs

      The typical car headlight can last 500 to 1,000 hours, but there are a lot of factors that can change that. In fact, some headlight bulbs are efficient enough to last well over 30,000 hours. That means the best way to know when to start looking for warning signs that your bulb may be nearing the end of its lifespan is to know what type of headlight bulbs your vehicle uses.

      Halogen: 500-1,000 Hour Lifespan

      HID: 2,000 Hour Lifespan

      Xenon: 10,000 Hour Lifespan

      LED: 30,000 Hour Lifespan

      When thinking about a headlight bulb’s lifespan, it’s also important to remember that although headlight bulbs can be rated to last hundreds or thousands of hours, there are many real-world factors that affect their overall lifespan. Prolonged use and other factors can have an impact. It’s also possible that your bulb may have a factory defect or could deteriorate over time which can cause the headlight bulb to burn out quicker than expect. To stay safe on the road, it’s important to be on the lookout for any signs that your headlights may need to be replaced and have them checked or replaced when you first begin to notice these warning signs.

      Know the signs of when to change out your headlights

      Some Important Safety Tips

      The chances of running into any issues while working on your headlight assembly are relatively low in comparison to a lot of other automotive procedures. However, it is still necessary to outline a few essential safety guidelines when operating on any vehicle.

      • Your engine is hot. Wait for it to cool down before working on it in any way. Especially avoid any metal components and pipes around the engine block.
      • Turn the engine off before you work near it. Use some basic common sense. Getting your hand sucked in by a rotating belt or other assembly is no one’s idea of a great time.
      • Be careful while working near electrical areas. Thinking about using a fork to get into that hard-to-reach area in order to test a wires connection? Think again. Again, always think of ways to avoid being lit up like a Roman candle.
      • When in doubt…If you have to think about it, it’s more than likely a bad idea. Use your brain.

      Headlight Fuse Keeps Blowing Out

      If you keep blowing a headlight fuse, give these simple steps a try.

      1. Unplug the light, pull the switch, and see if the fuse blows. If not, the problem is not in the wiring.
      2. Make sure you have purchased the correct wattage of bulb.
      3. Ensure that you do not have a faulty or damaged bulb.
      4. Check and see if your high beam bulb is the issue. If so, replace it.
      5. Check all wired connections and look for any exposed wiring.

      Headlight Bulb Keeps Burning Out

      Should you find yourself replacing your headlight bulbs way too often, there more than likely is an underlying issue. Before you take your car into the mechanic consider the following options:

      • Don’t handle the bulb with your bare fingers. Oils can cause bulbs to burn out quickly. Handle all headlight bulbs with surgical gloves and replace any existing bulbs that may have been handled incorrectly.
      • The problem could be in your installation process. Look up online videos and guides on how to properly replace your specific vehicle’s headlight.
      • Make sure the bulb is held securely in place, with no wiggle room or unnecessary motion. Bulbs that are prone to excess motion are known to break and burn out much faster.
      • Check your bulb sockets for signs of corrosion. They may need replaced completely. We have a large selection of salvageable Nissan, Toyota, and Ford parts/accessories should this be the route you decide to take.

      Headlight Flickers On and Off

      How to fix a low beam headlight

      Faulty headlights can lead to a dangerous situation on the road!

      Should you find yourself with a headlight that is flickering on and off, the most common issue is a poor connection somewhere along the line.

      First, try the simple fix by checking your battery clamp connections. They can gradually become loose from your engine’s constant vibration. Try wiggling every wire in the headlight circuit (don’t electrocute yourself) to see if you can pinpoint a specific culprit. Try and establish a more sturdy connection when a wire is singled out. In a worst-case scenario the entire headlight wiring assembly may need replaced by a professional. Also, as with other troubleshooting issues, if you are using a bulb with too high of a wattage, this can make your headlights flicker as well.

      Headlight’s Low-Beams are Malfunctioning

      Unless blinding everyone else on the road with your hi-beams simply because one or both of your low beam lights are malfunctioning is your thing, then it’s time to get to work, and troubleshoot your low beam lights.

      • If it is just a single faulty bulb, try replacing it temporarily with the bulb from the opposite headlamp. If it works, the bulb simply needs replaced.
      • The most common reason for faulty low-beam lights is a blown fuse. Check your car’s owner’s manual for information on how to access the fuses and where they are located. Check for melted wires leading to any of the fuses, and replace said fuses if necessary.
      • Use a voltmeter to make sure that power is actually running to your headlight. If not, then the problem is in your wiring. At this point, a mechanic should be consulted.
