I tried pulling out one bulb and it dies out. As for running on highbeam...hahahha thats what i'm doing. I still would like to know the problem thou. This only occurs during idle. High and low beams work. even the parking lights work. The Passing button work too. It runs idle great when they are off but not in CA. I checked the voltage with a meter at idle and at 7k. The voltage goes up, so my stator works fine. I have to try and check it when at idle in low and high to see how different they are. You firgure when the low beam is on the voltage would be higher and when high is on, the voltage would drop and it will die? My problem is backwards? Hmmm
