How to Fix a Low Beam Headlight?

Let's face it; nighttime driving is already dangerous with people being reckless with their cars! And a defective pair of low beams can make it even harder. Also, high beams are not preferred as they can blind others.

Repairing a low beam light is a simple task. Most car drivers are skilled enough to do it with a few simple instruments. However, your car may have more significant electrical cabling issues if you still have difficulties after changing the low beam headlamp.

In addition, traveling with a defective low beam can lead them to danger. It makes it more difficult for incoming cars to see them, particularly at sharp corners and while driving off-track on country roads.

How to repair a headlight's low beam

Step one: Detect the defective lightbulb

During traveling, it is simple to identify a flat tire. But, determining which lightbulb is damaged in this case, it's a little tough. Park the vehicle off the road and test the headlamps with the engine running.

Next, return to the car and activate the full beams. Some automobiles use one lightbulb for both the full and low beams. If the full beam on the same lightbulb functions, then the problem is mechanical.

If the full beam doesn't function, the lightbulb is defective and should be replaced for both full and low beams. If the full beam on the exact lightbulb functions, then it must be a cabling problem. So if the full beam does not function, the lightbulb is defective and needs to be replaced.

Step two: Get a new lightbulb

The next step is to purchase a new lightbulb as soon as possible. To avoid returning to the local automotive shop due to incorrect lightbulbs, getting an identical pair for the vehicle's light casing and type is essential.

You can find vehicle lightbulbs that are often labeled with numerals and letters. Such as H2, H11, H7, H1, and H5. Verify the letters or numerals on the defective lightbulb and purchase a substitute with identical numbers.

Step three: Install a new lightbulb

When removing a new lightbulb from its package, I suggest using cloth or gloves. This is due to oiliness on the hand that might degrade the crystal of the lightbulb, causing it to ignite more quickly and shortening its lifetime.

Insert the replacement lightbulb into the headlight socket while wearing gloves or wrapping it in a napkin. If you want to learn how to replace automobile headlights, please review our older articles.

Now, check that the lightbulb is securely set in the light casing. And avoid applying pressure to avoid breaking or cracking the lightbulb.

Further Issues with Headlights

When working with halogen or Xenon headlights, things might get more difficult than when working with conventional halogen light problems. However, it's common for an HID lightbulb to smoke out.

You must also consider numerous other possible failure areas. The lightbulb might have burnt out, or the issue could be a faulty ignitor or cabling problem.

Gently removing both lightbulbs and replacing the one that does not function is the simplest approach to determine whether the HID lights are defective. The problem might be complex if the stock lightbulb does not illuminate when put in the other connection. Then you must hire an expert to fix your headlights.

Frequently Asked Questions

Why my low beam headlamps are not working?

The most probable reason is a blown fuse, headlamp relays, light control, dimmed button, or faulty cabling. Approximately the only easy-to-repair reason is a damaged circuit. Check the manual's handbook to identify the primary switch for the light circuits. Then change it with a switch of the same amperage rating.

Why don't my low beam function, but the high beams do?

Although low beams are used more often than high beams, they end up burning out significantly more quickly. If the low beams stop functioning, but the high beams continue to function, it is likely that changing the lightbulbs with original lights will resolve the issue.

Can I replace the lightbulb on my own?

Absolutely, it is often simple to replace a lightbulb. The majority of LED or HID lightbulbs manufactured today are easy to change. Thin cable clips or spinning bolt action clamps hold them in place.

Can I use full beams if my headlight is detached?

It is unlawful to drive with a burnt-out light. It is also criminal to believe that it's better to use the high beams since you cannot see also with just one headlight operating.

Why do my lights only operate on full beam?

If a light circuit burns, the headlights may stop functioning. The majority of headlamp circuits have a relay that shifts electricity among full beam and low beam headlights. If the relays malfunction, electricity may be supplied to the full beam, not only to the low beams.

Final Note

Repairing a defective low beam is simple and may be accomplished by anybody without advanced mechanical knowledge. Nonetheless, if changing the damaged lightbulb of the low beam doesn't resolve the issue, the actual reason may be an electrical fault.

For which you might have to need the assistance of a specialist. However, if the problem is a cloudy headlight lens, the lenses may be simply restored using a headlamp repair kit.
