My new to me deck/steaming light combo has a round wire coming from the steaming light that contains a red and black dc wire, however the deck light has a separate round wire that has a dc red, black and white wire. They are LED lights and there was no wiring diagram included. I've not yet come across a three way DC wire yet with a white. Were the two lights meant to be wired to an ON-OFF-ON toggle switch and the white wire is used as a common ground? Sorry dont know whats up with this funky image formatting.
