Every light in my car pulses/flickers when my headlights are on (dash lights, headlights, taillights, interior lights, etc.). I have no idea why. I have a good battery and a good alternator (I had both of them tested). I pulled out my battery tray and sanded down/cleaned up the grounds. Someone told me that could be it. That still didn't fix the problem. It doesn't matter if The car sits at idle, or I rev it up. It still does it. Most of the time it pulses/flickers fast, but sometimes slow. I cant figure out what it is. A bad ground somewhere else? A short? I'm trying to get this problem fixed A.S.A.P, I don't really want to get pulled over and ticketed for something stupid like this. Cops are a**holes around here.
Everyone's help is greatly appreciated
