Sorry, not even going to think about it. Two reasons, 1. I don't need to get killed and 2. not easy. If I were to guess, its the mechanical gage backing and/or face material with some sort of edge illumination. Think Dodge Intrepid and Chrysler LHS's use the same setup. It does NOT change color at night like the older Max's. White faced at all time. Illuminated it's a kinda teal blue green color.
