It's not quite so easy as that. I have a 12 volt dc plug in he back with a lighter socket too, but they stay on all the time, which I need. maybe a little relay with an override switch, just to the back light socket. I learned to drink cokes warm in Vietnam. It makes life much easier. But I do need to keep a certain amount of food cold, or at least cool.
