I have a '04 Denali and am considering upgrading high, low, and fog lights to HID. The issue i have is that my low beams flash twice while using my remote start (on start, lock and unlock). I turned off all the light flashing options in the vehicle programming but this did not work. The remote start installer said that only the parking lights should flash but there wasn't anything they could do to fix it. Does anyone know if this "flashing" will be a problem if i upgrade to HID?
