My interior lights are flickering *the lights that light up when the door is open*. I was reving my car and I noticed once I let go of the gas my lights would dim as well. I think I can see it in the headlights too. I just recently bought and a new alternator and battery from autozone. Right now I don't have any ideas what could cause this. Oh one more thing. When I bought the alternator it didn't have a place to put the nut that you use on the bracket for wire harness. I didn't think much of it since it was just a bracket but yeah trying to tell you all the info.
