Scottie, I have shied away from the HID headlight bulb, because it requires extra wiring & $$. I have a Xenon bulb that seems good enough, due to my Diamond cut reflector & clear non diffusing Glass. I'd like to try an LED headlight bulb, as I have not seen one in action yet. I do run an LED in my headlights pilot bulb position, to save my more expensive bulb for night time.
