So this problem just recently started.

My left (driver's side) headlight turns on and off randomly when I'm driving and I don't know what's causing it. There is no pattern. Doesn't matter if I hit bumps or not. It just randomly turns on and off.

I checked the harness to see if it was loose and the wires to see if they were in place or not, but everything seems fine. If I drive with the high beams on, they stay on all the time. The normal low beam lights are the only ones that will turn on and off randomly.

Anyone seen or heard of this problem before? Any help?

 

try changing the bulb

 

swap the bulbs.. its free and youll know if its wiring or the bulb depending on what happens next.

 

also check the connections

 

thanks i'll get right on that.

 

Probably one end of the low beam filament is loose. When it touches, the light is on. Vibrations knock it loose again, and it goes off.

Swap bulbs.

this happened to me too. i had to hit the headlight and it fixed the problem.

 

^ When all else fails, just hit the damn thing haha

 

well it's not the bulb. so i'm guessing it's the harness. wire might be loose somewhere...

actually i have and that's what actually fixes it most of the time. lol
