Go to auto zone and buy a neon light interior lighting thing that says "bumps to the music or, lights to the music."
How it does that is it has a wire that vibs to the bass and completes the circuit when it does that. There you can some how wire a relay from that or some eletrical stuff to do that. Very dificult. I don't know how. However it is possible.
