Auto Electrics: 5 Reasons Your Car's Lights Are Flickering

by Brittany Marshall

No one likes it when their car's lights start flickering. Not only is it distracting, but it can also signify a severe electrical problem. If your car's lights are flickering, don't ignore this issue! Here are five potential reasons why your car's lights might be flickering. Read on to discover everything you need to know.

1. A Faulty Alternator  

A faulty alternator is a very common reason for flickering lights. The alternator is what powers the electrical system in your car, so if it's not working properly, the lights will start to flicker. If you think that the alternator might be the source of the problem, get your car to a mechanic as soon as possible. 

2. Loose Electrical Connections

Another common reason for flickering lights is loose electrical connections. When the connections between the battery and the electrical system are loose, it can cause the lights to flicker. This type of issue is usually an easy problem to fix. A qualified mechanic will be able to tighten the connections and stop the flickering. 

3. A Wiring Problem

If the wiring in your car's electrical system is damaged, it can also cause the lights to start flickering. This is usually a more serious problem that will require professional assistance to fix. 

4. A Problem With The Headlights

In some cases, the reason that your car's lights are flickering may have nothing to do with the electrical system at all! For example, if your headlights are old or damaged, they may start to flicker. An auto repair shop can usually fix this problem by replacing the headlights. 

5. A Faulty Battery

Another potential reason for flickering lights is a faulty battery. If your battery isn't quite holding its charge, it can cause all sorts of problems - including making your lights flicker. If you think that your battery might be on its last legs, get it checked out by a professional as soon as possible. 


If your car's lights are flickering, don't ignore them. Take your auto to a qualified mechanic and have them take a look. In most cases, flickering lights are caused by a simple problem that can easily be fixed. In some rare cases, they can indicate a more serious issue. Either way, it's always best to err on the side of caution and get your car checked out by an auto repair shop if you're concerned about its safety.
