I was thinking of this while cruising home from my girls house. Does anybody else think it would be possible to make various color digi dashes? I think that would be so cool. I guess I am weird like that.
Have you thought about changing the bulb colors, or getting those covers for the bulbs that changed the color? I wonder if changing the reflective surface of the diffuser would have an effect similar to what you seek. It's worth a shot, can't cost you much.
color on hte digital dash ( at least 87's ) is controlled by a colored sheet of plastic, it is one piece, and would have to be cut, and new color sheets overlayed into it. Have been toying with changing the color of the numbers on mine, but have not been able to locate a source for the plastic sheets
