Hello. Last year I saw an add in the back of a motorcycle mag that showed battery operated licence plate bolts that light up when you twist the top of them. I put my plate on the side of the swingarm and don't want to run a wire to the plate for a light. Does anybody know where I can get the battery powered light up licence plate bolts. Also does anybody have them on their bike now and do they work good enough to not get in trouble? Thank you. George.
