I've seen a website somewhere documenting how someone used two pocket LED flashlights, the kind that normally use three AAA batteries, to make stoplights that fit inside the top bed rolls. I think a piece of PVC pipe was used as a spacer to center the flashlights in the bed rails. A piece of red polycarbonate plastic was fitted over the main lens. LEDs will work on wide voltage variations with no ill effects.
