Mercedes-Benz of Georgetown can show you what makes the lights on your vehicle flicker.
If you see your lights dimming while driving, it’s probably due to a battery that is dying. If your battery checks out fine, there are other common trouble areas that are likely responsible for the issue. No matter the cause, you should get the problem diagnosed and fixed as quickly as possible. If your lights aren’t working properly, you might become a hazard to yourself and other drivers.
The 3 areas dimming car lights can occur are:
Since the battery is the easiest part to replace, this is where a mechanic will look first. If you think the battery is bad, bring it here so we can diagnose the problem and get the right OEM parts for your vehicle. While most cases result from a bad battery, there are other components to consider.

If your vehicle battery isn’t the cause of your flickering car lights, you might be dealing with a failing light bulb. Failing bulbs are an easy fix and present an opportunity to upgrade to new LED bulbs.
If it’s a bad fuse, you may be dealing with a larger issue since fuses are a safety feature. A fuse dies when there is excess electrical current flowing through it. For example, if the anti-lock brakes are installed with a 10amp fuse, and the fuse receives over 10amps of electricity, the fuse will fail. In this situation, a failed fuse would cause your anti-lock brakes to fail. If there is a fuse that regularly fails, bring it in and we will thoroughly diagnose the bigger, potentially more serious issue.
Lights flickering on the dash may also be signs that the alternator is dying. Consider this, you start your vehicle with battery power, but the alternator supplies the power that keeps your car running. If you drive an old vehicle with halogen headlights, you may notice them slowly get dimmer with a failing alternator. For new cars with LED or HID lighting, they may flicker or just stop functioning altogether.
A dying light switch, either the interior light dimmer or the headlight switch knob, should be considered when you have flickering lights on your car. In some rare situations, replacing a worn switch might solve the problem, especially in old cars or vehicles with excessive wear. If your vehicle is newer, there’s a chance it could be a sign of a bigger issue with the car’s electrical system.
