i just got a couple of 18" underbody neon light tubes for my ride. im pretty good with body work but i have no idea how to wire these suckers. all i know is that the tubes each have a built in transformer and the black and red wire coming out of it. i want to be able to have them on without my headlighs having to be on, if not possible its ok, i also want to have a switch for them in the dash, what am i going to need to get and what should i do??
