I used sticky aluminum tape. Cleaning the prisms and the rest of the panel helped a litle, but it is still far too dim.

I don't think that the paint would chip off. It's not out in the weather. The numbers on te speedometer are painted on and they seem to stay stuck pretty well.

I think the key is to use a number of LEDs. The difficulty is that the one I have seen are of far lower voltage. I know that they can be linked in series, or is it parallel to get them to run on 12v. 2+2+2+2+2+2=12, but I am unsure about how to do this, since I am no expert on electricity.

I was thinking about using fiber-optic strands as well. If someone will whomp up a design, I bet I can find the materials.
