There is no way I would spend $200 plus for a Design Shine tail light, that damn thing is brighter than a motorcycle tail light, why? If a motorcycle doesn't need anything that bright what makes you think a bicycle does? And how difficult is it to make a tail light with five 1 watt LED's in a row for less than $100? Or even two 3 watt LED's? their doing that in headlights, just move the LED's into a red lens case. Just doing that would make the Design Shine $200 tail light look like junk.
