How about something like that: Electroluminescent Flatlite Panel or ElSheet I know RS components have some but they are only 120mmx130mm, but I think you can cut them to any size/shape you want... That would look cool. I think somebody did that, can't remember the name of the project, but he had his TJ07 plexi midplate illuminated from underneath using something like that... it was quite nice. Edit: I found the Mod I was talking about: the name is .:Filtration:. It was one of the best mods around, triple loop and everything, and the thing that made it pop was the EL sheet: Filtration EL sheet instal and cutout You shoud check it out, it looks stunning! I think you can get those EL sheets in white, but I'm not sure about the size he uses. Hope that helps!
