What Makes The Lights On Your Car Flicker

what makes the lights on your car flicker

Lexus Southwest Houston can show you what makes the lights on your car flicker.

If you see your vehicle lights dimming while driving, it’s most likely going to be from a battery that is dying. If your car battery is normal, there are other common trouble areas that could be causing the issue. No matter the cause, it’s imperative that you have the problem diagnosed and fixed ASAP. When your lights aren’t working properly, you could become a hazard to other drivers.
The three areas dimming car lights generally happen are:

  • Interior lights
  • Headlights
  • Dashboard lights

Since the battery is the most convenient part to replace, this is where most of us will look first. If the battery is dying, bring it here so we can diagnose the issue and get the right parts for your vehicle. While most cases result from a bad battery, there are other culprits to consider.

Bad bulbs or fuses

Bad bulbs or fuses

If the vehicle battery isn’t the cause of your flickering car lights, you might be looking at a bad bulb or a bad fuse. 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 could be dealing with a bigger issue since fuses are a safety feature on your vehicle. In most cases, a fuse fails when there is too much electrical current runs through it. For example, if the anti-lock brakes are connected to a 10amp fuse, and the brake system receives over 10amps of electrical current, the fuse would fail. In this example, this could also cause your anti-lock brakes to fail. If there is a fuse that regularly fails, bring your car in so we can accurately diagnose the larger, potentially more serious issue.

Alternator

Flickering dashboard lights may also be signs that the alternator is dying. Consider this, you start your vehicle with power from the battery, but to keep your car running, the power is supplied by your alternator. If you have an old vehicle with halogen headlights, you may see them gradually get dimmer with a dying alternator. On newer cars equipped with HID or LED lighting, they may flicker on and off or just stop functioning altogether.

Headlight switch going bad

A dying light switch, whether it’s the interior dimmer or the headlight switch, should be considered if you have flickering car lights. In some situations, replacing a worn-out switch may solve the problem, especially in older cars or vehicles with excessive mileage. If your vehicle is new, it could be symptoms of a bigger concern with the car’s electrical system.
Understanding these issues can feel overwhelming, so if you experience any issues with the lights flickering on your car, bring it to us immediately. Our trained technicians will do a thorough investigation and provide you with options for fixing the flickering car lights.
