The alternator may be failing. Drive to your local auto parts store and they can test the charging system for you for zip.
Have your alternator tested. They will sometimes do that when they are putting out low outputs at low rpm.
you can also have a wire that is exposed and that can be making them to flicker
one or more headlights don't work but others do.none of the headlights will work.high beams work but low beams don't and vice versa.lights flicker and sometimes go dim.
The alternator is on the way out.
Probably your alternator.
When a cars headlights, AC, and radio are losing power, it is possible the alternator.
Sounds like a loose connection on the back of the bulb. Unplug them and plug them back in making sure the plug in all the way on.
voltage regulater on the alternater is going bad
The headlights may flicker.
Yea its an electric or body comtrole module .about 400.00to repair at dealer. Will cause lights to flicker off & on and sometimes horn will chirp also while driving
Sometimes the ground strap to the body of the car can come loose. This will cause things to flicker. Ground from the battery needs to be connected to the engine block, the frame, and the body to keep things working properly.
You may have a pull on your batt, or a surge.
