Watch my video of my bus headlights being weird

[luvrbus]

Agreed ^
I wonder if mine are set up low voltage as daytime runners. Headlight switch used to turn the high beams on but mysteriously quit. I have issues to chase lol. Bob I'll be checking the voltage to them asap

Does the dimmer switch work do have high and low beams ? my high beams won't work without the switch turned on

Scott is it possible the dimmer switch was set on high beam, and when you turned the headlight switch on they just came on because of that? Have you tried turning on the headlight switch after you start the bus  and see if the headlights stop flickering?

Scott, are these HID Xenon or halogen projector headlights?  The bright white color of the lights in the video makes me think they are HID Xenon.

HID projectors will have a ballast and should not be all that sensitive to voltage unless it is really low.  If it is HID I would try hooking a battery directly to the ballast to see if the headlight lights up.  Do not connect to the bulb itself.

Cliff, I have a floor dimmer switch and it does nothing. When I first bought the coach the headlight switch on the dash activated the high bEams. Now it does nothing. The headlights light up and do not flicker once they are both fired and lit. Yes they are HID xenon. Actual gas fired units with ballasts like Lexus and bmw etc.

Since they are HID I would definitely try to get access to the ballast and provide power directly to the ballast.  Unfortunately, the ballasts usually have a plug for power so I am not sure how you would get power to the ballasts without possibly cutting wires and then splicing them back together.  I retrofitted 90mm BiXenon HID projector headlights into my bus, but most of the work was the mounts for the headlights.  The electrical was the easy part.

I would be happy to help with your headlights if I wasn't 1,000 miles away in Minnesota.
