Common Issues

Flickering Headlights

If your headlights are flickering, it could indicate a problem with the battery or alternator. A faulty alternator can cause the headlights to dim or flicker, and in severe cases may lead to total headlight failure. To determine if this is the issue, use a voltmeter to test the battery voltage. If the voltage is below 12 volts, it could be a sign of a faulty alternator.

Blown Headlight Bulbs

If your headlights suddenly go out, chances are that you have a blown headlight bulb. Replacing the blown bulb is a relatively simple process, but it requires some basic knowledge of car mechanics. In most cases, all you need to do is remove the broken bulb and replace it with a new one. However, it is essential to check the wiring harness and connectors for any damage before installing the new bulb.

Corroded Wiring

Corroded wiring is a common problem that can cause your headlights to malfunction. Corrosion can occur due to water penetration or exposure to harsh environmental conditions. If you notice any signs of corrosion, remove the affected wires and clean them thoroughly. You may also need to replace damaged connectors and wiring harnesses to ensure proper functionality.


Can I replace my headlights myself?

Yes, you can replace the headlights yourself if you have some basic knowledge of car mechanics. However, if you’re not confident in your skills, it’s best to seek the assistance of a professional mechanic.

How do I know if my headlights are properly aligned?

To determine if your headlights are correctly aligned, park your vehicle on a level surface facing a wall or garage door. Turn on your headlights and check the beam pattern on the wall. If the light is pointing too high or low, you may need to adjust the alignment screws located on the back of the headlight assembly.

Why do my headlights keep burning out?

There can be several reasons why your headlights keep burning out. Some common causes include power surges, high vibrations, faulty connectors, and poor quality bulbs. To avoid this issue, ensure that you use high-quality bulbs and check the wiring and connectors regularly for any signs of damage.

Is it safe to drive with one headlight out?

No, it’s not safe to drive with one headlight out. Driving with just one headlight can reduce your visibility and make it difficult to see the road ahead. It’s best to replace the faulty bulb as soon as possible to ensure your safety on the road.

What should I do if my headlights are not working at all?

If your headlights are not working at all, the first thing you should check is the fuse. Locate the fuse box and check the headlight fuse for any signs of damage. If the fuse is blown, replace it with a new one. If the fuse is intact, the problem may be with the wiring or relay, and you may need to seek the assistance of a professional mechanic.


Having properly functioning headlights is essential for your safety on the road. If your headlights are malfunctioning, use the information in this article to diagnose and fix the issue.
