Headlights not working. Any help appreciated.
 

Hi, first post on here. I have a r53 road legal track car iv built over a few years. Randomly my headlights stopped working. They are the xenon ones. I have side lights and full beam but only if stalk held in the position. A Delphi laptop with obd can turn them on and they work fine. I have replaced the stalk for a new one. I have replaced the bcm. Even my mechanic mates just have no idea what’s going on. I’d rather not have to drive around with a laptop operated pair of headlights so any guidance or maybe somebody that has experienced the same issue would be very much welcomed! Many thanks, mark
