Why do your head lights and tail flicker while driving?

Headlights and taillights should not flicker while driving. If they are, it is a sign of a problem with your electrical system. Some possible causes include:

* A bad battery: A weak or damaged battery can cause the voltage to fluctuate, which can lead to flickering lights.

* A bad alternator: The alternator is responsible for charging the battery. If the alternator is not working properly, it can cause the voltage to drop, which can lead to flickering lights.

* Bad electrical connections: Loose or corroded electrical connections can also cause flickering lights.

* A faulty light switch: A faulty light switch can also cause the lights to flicker.

If you notice your headlights or taillights flickering while driving, it is important to have the problem diagnosed by a qualified mechanic as soon as possible. Driving with flickering lights is not only dangerous, but it can also lead to further damage to your electrical system.
