Thanks for the reply. The left headlight usually looks normal, but the right one can be anywhere from off to bright, usually very dim. I have confirmed that the voltage at the light is changing. Also, with the lights on, the high beam and right turn indicators come on, and the right turn signal will not flash (just comes on solid). These problems go away when the lights are off. I thought it seemed like a bad ground. I'll check the things you mentioned. Thanks again!
