Currently tied into the cockpit lights. I ran a 16 AWG wire around the boat for the speaker led's, cupholders, and any other lights I add. It is connected behind the helm, but I may move to a separate switch with a dimmer. This was just the easy way to do it, and use the 3 Amp breaker for the cockpit lights, which I switched to blue LED last year.
I'm doing the entire boat in SeaDek. That is the swim platform kit, waiting on the re-sized cockpit kit.
