umm, i wasnt aware that saleen guages completely light up. Those arent indiglos... all thats going to light up are the needles and the numbers and the little hash marks to tell you your speed. Did you buy a complete cluster or did you change just the face out on your own? I could see a couple of the lights int he cluster being burnt out... that would cause things to not light up. beyond that i dont really know. Also, how are you calibrating that??
