I have a HID headlight kit installed (not a retrofit) and am having some issues with one of the headlights not always cutting on. If I cycle the power to it I can get it to come on. That makes me think relay. The odd thing is sometimes one headlight does it and sometimes its the other. Have any of you had this issue and found it was hopefully the relay and not the ballast going bad? It happens often now so I'm looking for a fix.
