For the last two weeks my right front headlight has had a poltergeist. Sometimes when I turn on the headlights, the little warning light comes on telling me that a light is out. When I look at the headlight it is noticeably dimmer than the other. HOWEVER, just as often, the headlights are fine and the little warning light does not come on. Do I have a bulb problem or short in the wiring? Also, when the headlight is dim and the warning light is on I can put the brights on and the warning light goes away (I don't think this indicates anything, I think this is what sis supposed to happen). Any thoughts?
