Quoted from Phbooms:Comet sells really short ones that would work for trough lighting but nothing long enough to go across the back
Have any idea what length it would take to the entire width (I can measure this myself in a day or two)? And what colors are you interested in? I've been considering adding a little kit to do these. One bummer is that you wouldn't want to tap into power from a socket on the playfield, as that would stretch/stress the wires when you lift the playfield.
