I wrecked my car going like 2 mph and ever since then my cars lights pulse. And I mean all the lights; headlights, a/c lights, dome light, and even my check engine light. Need a hint as to what would cause this??? I already changed alternator and it still does it. Ohh yeah even my speedometer jumps. Help me please

 

My indicator lights flashed like a disco one time. Pull off the neg cable on your battery and let your car reset itself. Plug it back in in like 10 minutes. See if that fixes it.

 

there are two ground boxes on the inner frame rails close to the headlight. they are white and have alot of black wires running to them. there is one on each side of the car. it has a 10mm head. tighten it or ground it somewhere else. these are the grounds for your lights. if there not tight, blink blink blink go the lights.

 

thanx, anybody else have a suggestion?
