Re: LED Polarity.
I recently installed 12v LED railing lights the other day and saw no mention of polarity in the instructions. The 2 wires from the light were both black. I think they had a little analyzing and switching circuit so they would work either way. It would be nice if LEDs in our trucks worked that way.
