You have not yet seen a tail light until the bike shop kid walks across the parking lot about 100 yards away in broad daylight on a sunny day and points this blinky thing back at ya, then the shop owner tells you to turn around and look back into the bike shop at all the bike reflectors reacting to that 'Cree' LED~
