I changed to what the Car Quest Guy said were brighter bulbs, but I don't see any difference. Yeah, somtimes they just go out completely when I am adjusting the dimmer. Probably just need to get a new switch. The only place I have been able to find a new one is Atlas Obsolete Parts, and one has to buy the high/low beam floor switch with the headlight switch and they want $68 bucks for the pair. Does anyone else know where to get one for the 67 "B" bodies? Yearone only has them for the "A" bodies.

Thanks everyone for your input!!
