Driving at night or in poor weather without working headlights is not only unsafe — it’s also illegal in Texas. Whether they’re dim, flickering, or completely out, headlight problems should be addressed immediately. At Marble Falls Auto Center, we’ve helped countless drivers restore their lighting systems so they can drive safely and confidently.
What Causes Headlights to Stop Working?
1. Burned-Out BulbsThe most common reason is a simple burned-out bulb. Over time, headlight bulbs naturally wear out and need replacing. If only one headlight is out, it’s likely just the bulb.
2. Bad Headlight Switch or RelayIf both headlights fail at the same time, the issue could be with the headlight switch, dimmer switch, or the headlight relay — all of which control power to the lights.
3. Wiring ProblemsCorroded, frayed, or damaged wiring can prevent electricity from reaching your headlights. This issue is more common in older vehicles or those with past electrical repairs.
4. Alternator or Battery IssuesIf your headlights are dimming while you drive, it might not be the bulbs at all — it could be a weak battery or failing alternator that isn’t delivering steady power.
5. Fuse FailureA blown fuse will immediately cut power to one or both headlights. Replacing it is simple, but it’s important to find out why it blew in the first place.
How to Fix Headlight Problems
At Marble Falls Auto Center, we start with a quick lighting system inspection. We check the bulbs, wiring, fuses, and switches to pinpoint the issue.
Sometimes the fix is as simple as replacing a bulb or fuse, but in other cases, it may involve electrical repair or alternator service. Our ASE-certified technicians can handle it all so you can drive safely again.
Why You Shouldn’t Ignore Headlight Issues
Driving without functioning headlights isn’t just dangerous — it can also result in a ticket. Dim headlights can reduce your reaction time at night, and completely non-functioning ones make you nearly invisible to other drivers.
