2011 Chevy Silverado, installed HID system with 12v relay triggered by right side low beam headlamp socket. This ran fine for 5 months then the headlamp socket driving the relay went dead, fuses and relay tested fine. Switched the relay trigger over to the left side low beam socket, only worked for two weeks then it went dead. Again, all fuses and relay test fine. Is there another set of fuses or relay that is in-line that could be the culprit? If I take a 12v source and feed it into the HID relay trigger, the HIDs work again. High beams still work fine.
