Why don't my head lights and break lights work? Please help
What is your question?
One day all of the sudden my headlights and brake lights aren't working. Im assuming that maybe it's because my amp from my stereo, maybe it loosened some kind of wire. I don't know but I have checked the bulbs all the fuses even the little fuse thing underneath my brake pad , and nothing. My brights work though. that's what I'm using at night, and my fog lights work and tail lights. what is it that I need to check or try? tonight while I was rolling up my window I noticed my lights were flickering each time I pressed down on the switch to roll up my window. What does this mean?
What makes this problem better or worse?
Nothing that I have already tried

Hello, did you recently install the stereo? How are you powering your amplifier?
If you have lights flickering when rolling up the window with the power window switch, have recently performed vehicle modifications including stereo and amplifier installation and your high beams still work when your regular lights do not, it sounds like a wiring short for some kind of open circuit related too the lighting. Hands on testing of the related circuits - with the aid of electrical testing equipment and a workshop manual including wiring diagrams that will help determine what color wire at what connector does what - is essential.
