led controller?

This is my first post here and i just was wondering  if someone could clear some things up for me. I am not interested in making my own led tubes or anything. But i have noticed those tubes that have a bunch of diferent colors of led lights in them. Well I was wondering if it would be possible to wire up the interior and exterior led lights up to a single controller. As well as having a few switches, one of which would be for the main system power, one for the the exterior lights, one for the interior lights and one for strobing lights. Now, i was curios if there was some sort of central elictrical controller system for intricate led systems. I have searched around and could not find much. I would just like to be able to change all of the led's colors from one point instead of individually. I was also wondering if i could get one transformer that would handle a system like that, so alls i had to do was wire the whole system to a central point in my car. Any insight would be greatly appreaciated. Oh and my car is a 1999 acura integra special edition (ls).
