i have these white face guage covers. (white guage with red numbers and lines) they just go over top of the stock guage and the factory back light on the top of the guage cluster lights them up at night. this may sound cheap, but they look phat, have the same accuracy as stock, you dont have to mess with the needles or anything, and they give the same appearance as most of the indiglo guages. oh yeah, you dont have to worry about where to hook the stuff up to either. just my $.02.
