Whats wrong with my headlights?
Headlights are an essential safety feature of your vehicle, ensuring visibility during nighttime driving or in poor weather conditions. If your headlights are malfunctioning, it can be both frustrating and dangerous. At Kevin's Autos, with years of experience in car maintenance and repair, we’ve seen a variety of headlight issues. In this article, we’ll explore common problems with headlights, their causes, and how to address them.
Common Headlight Problems
There are several reasons why your headlights might not be functioning properly. Below are some of the most common issues:
- Burned-Out Bulbs: This is the most frequent cause of headlight failure. Over time, the filament in halogen bulbs or the components in LED or HID bulbs can wear out.
- Faulty Wiring: Damaged or corroded wiring can interrupt the electrical flow to your headlights, causing them to flicker or stop working entirely.
- Blown Fuse: A blown fuse in your vehicle’s electrical system can prevent power from reaching the headlights.
- Bad Headlight Switch: The switch that controls your headlights can wear out, leading to inconsistent operation.
- Dirty or Foggy Headlight Lenses: Over time, headlight lenses can become cloudy or dirty, reducing the brightness of your lights even if the bulbs are functioning correctly.
- Alignment Issues: If your headlights are misaligned, they may not illuminate the road properly, even if they are working.
How to Diagnose the Problem
Before heading to the repair shop, you can perform a few simple checks to identify the issue:
- Inspect the bulbs for any visible damage or discoloration.
- Check the headlight switch to ensure it’s functioning properly.
- Examine the fuse box for any blown fuses related to the headlights.
- Look for signs of corrosion or damage in the wiring near the headlights.
- Clean the headlight lenses with a specialized cleaner to see if that improves brightness.
When to Seek Professional Help
While some headlight issues can be resolved with basic maintenance, others require professional expertise. Here are some situations where you should bring your car to a trusted auto repair shop like Kevin's Autos:
- If you’ve replaced the bulbs and the headlights still don’t work.
- If you suspect wiring or electrical issues.
- If the headlight alignment needs adjustment.
- If you’re unsure about the cause of the problem.

To keep your headlights in good working condition, follow these tips:
- Regularly clean your headlight lenses to prevent cloudiness.

- Replace bulbs in pairs to ensure even brightness.
- Schedule routine maintenance checks with a professional mechanic.

Frequently Asked Questions
How do you diagnose headlight problems?
Start your engine and turn on high beam, and then low beam. If you only see one of the headlights works, that means you have a burnt out headlight, replace it. If both headlights don't work, you have a bad light sensor.
What should you do if your headlights suddenly go out while driving?
Try the headlight switch a few times. If that does not work, use your parking lights, hazard lights, or turn signals. Pull off the road as soon as you can and leave your hazard lights on so that other cars can see you.
Why are my headlights not bright anymore?
Over time, the gas inside these bulbs gradually creates a film on the inside of the glass. If the bulbs in your headlights look dark, it is likely just build-up on the inside of the bulb, preventing light from escaping. Unfortunately, the only way to fix this problem is to replace the bulbs themselves.
What does a bad headlight ballast look like?
Visual Indicators of Ballast Failure: When inspecting it for potential issues, any burn marks, leaking oils, or swollen casing are indicators of failure.
Why would both headlights suddenly go out?
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.
Why is one of my headlights not working even with new bulbs?
A blown fuse can prevent power from getting to the headlights. Rust or corrosion on headlight connectors can reduce or prevent electrical continuity. A bad relay can prevent power from switching to the headlights on demand. Moisture inside the headlight housing can damage bulbs, wiring, and other parts.
Why are my headlights not getting enough power?
- Burned Out Bulb: The most common reason is that the bulb itself has burned out.
- Blown Fuse: A blown fuse can interrupt the electrical circuit to the headlight.
- Faulty Wiring: Damaged or corroded wiring can prevent electricity from reaching the headlight.
- Bad Relay: Some vehicles use a relay to control the headl
What are the symptoms of a bad headlight relay?
Ever heard a rapid clicking sound when you turn on your headlights. This rapid clicking. Sound happens because the relay's internal components are worn out the contacts struggle to connect properly.
What are the signs of a bad headlight switch?
Common Signs of a Faulty Headlight Switch
Problems When Switching Headlight Modes: A clear indication of a faulty headlight switch is difficulty in switching between different headlight modes. You might notice that the switch only functions in certain positions or causes the headlights to flicker or blink.
How to reset headlights?
Find the adjusting screw and turn the screws slowly clockwise to raise the height of the lights or counterclockwise to lower them. As you make your adjustment, make sure the most intense part of the headlight beam hits at or just below the vertical centerline you taped on the wall. Adjust the horizontal field.
