colored lighting overhaul

[Captain_Bravo]

As long as we're talking about lights, is there any way to effectively create and turn on new lights? I tried to build a space disco the other day, with a whole range of colored light tubes, but we couldn't figure out a way to make the damn light brackets we installed work.

I know that lights work off of APUs, and APUs are kind of weird, but is there a quick fix that could be implemented here? Buildable buttons or lamps that work when they're on electrified tiles or something?
