2manybikes - exactly my point about "tail light reflectors". In fact most have little or no reflective capability and are just molded design features that give unsuspecting buyers the impression they are getting some reflectivity when they are not. I am not sure how the PD Radbot measures against required bike reflectors but I know the old Cat Eye Reflex and new Auto lights are supposed to be full on bike reflectors. I just wish the new Auto ones had the same mounting on the back that the original did.
