Well once in a while when i drive it (my gf's car) the heater/lights seem to surge some times..then today as she was going out i noticed the pass side headlight was on, on low beam..when she went to high beam the driver side came on and the pass went out, as she was doing this she said the dash lights were going dim/brighter, just curious if you guys have any idea's to what is going on. also the battery light in the dash flashes on sometimes as well
