I did the LED in the vent thing. I have them wired up to the same switch that kicks on my underdash CCFL's. They are easy to do. If you wanted to have 1 switch to kick on all the LED's and then have other switches for other locations its not really all that much work. Just have the main power coming in to one main switch, then branch off that switch to other switches to control the other areas.

I went another route with mine. I have a relay running off the ACC ON where the moment I turn off my car all my self installed accessories turn off so there is no chance of me accidentally leaving them on and killing the battery. Only downside to this is I can't be cool like the rest of the boys and park my car with my underglow on. On the upside I can start my car without worrying about the bat being dead.
