What Does It Mean When My Vehicle Lights Are Flickering?

what does it mean when my vehicle lights are flickering?

Gene Messer Ford Amarillo can show you what what it means when your vehicle lights are flickering.

If you observe your lights dimming while driving, it’s probably going to be from a battery that is failing. If the car battery is normal, there are other common trouble spots that could be causing the issue. Whether it’s your car battery or something else, it is imperative that you have the problem diagnosed and repaired ASAP. When your lights aren’t working properly, you could become a hazard to yourself and other drivers.
The three areas dimming lights mostly happen are:

  • Headlights
  • Lights on the Dashboard
  • Interior lights

Because the battery is the most convenient component to diagnose, this is where most of us will look first. If the battery is bad, bring it to us so we can diagnose the problem and get the right battery for your vehicle. While there are cases caused by a bad battery, there are other components to consider.

Bad bulbs or fuses

Bad bulbs or fuses

If your vehicle battery is not the cause of your flickering car lights, you might be looking at a dying light bulb or a bad fuse. Failing bulbs are an easy and quick fix and present an opportunity to upgrade to new energy-efficient LED bulbs.
If it’s a blown fuse, you might be dealing with a larger issue as fuses are a safety feature. A fuse dies when there is excess electricity flowing through it. For example, if the anti-lock brakes are connected to a 10amp fuse, and the fuse gets more than 10amps of electricity, the fuse would fail. In this situation, your anti-lock brakes would fail due to the failed fuse. If there’s a fuse that continues to fail, bring your vehicle in so we can accurately diagnose the bigger, potentially more dangerous problem.

Alternator

Flickering lights can also be one of the signs that your alternator is failing. Consider this, you have battery power to start your vehicle, but the alternator supplies the power that keeps your vehicle running. If you drive an old vehicle with halogen lights, you may notice them gradually get dimmer with a failing alternator. For new cars with LED or HID lighting, they may flicker or just stop working altogether.

Headlight switch going bad

A failing light switch, whether it’s the headlight switch knob or the interior light dimmer, should also be checked out if you have flickering car lights. In some situations, replacing a worn-out switch may solve the flickering light issue, especially in vehicles with excessive mileage or older vehicles. If your car is new, it could be a sign of a more serious concern with the vehicle’s electrical system.
Understanding these concerns can feel overwhelming, so if you’re experiencing any problems with the lights flickering on your car, bring it to us immediately. Our knowledgeable technicians will do a thorough investigation and give you options for fixing your flickering dashboard lights.
