Flickering Lights

[92E34]

My flickering light problem has gotten worse. I've swapped LKM's and its not getting any better. All the lights flicker in the car, and it doesnt matter what speed the engine is turning. Sometimes it will be fine and not flicker, but when I am driving at night it is very noticible and almost looks like a strobe light. I checked all my grounds and connections to the alternator. Is there anything else it could be?

Maybe your light switch looks like this one

I had sort of the same problem, i checked the lines you did to the alternator. Then one day i noticed a group of ground wires on my driver side fender in the middle that had a loose nut on them :P fixed the problem

all the lights in the car eh.... either the switch or the dimmer unit.

the dimmer has some electronic components in it, so soldering going bad could cause the diode or variable resistor to freak.

But it flickers when the lights are off too. I'll re-check my grounds.
