Who's done it on an older boat not equipped with interior lighting? I'm thinking of doing my cupholders and maybe a few courtesy lights in the front and rear. Of course, like every good ricer I want to do some transom underwater LED's but that will have to be a winter project.

Who's LED'd their interior? Talk about the process, relative cost, wiring, where you purchased from, etc. I've seen threads on other forums but nothing Moomba specific.
