I seen a crotch rocket the other day and it looked like it had no lights on the rear :wtf: . Got to a signal on the boulevard and a tiny row of LEDs lit up with the brakes. Mounted right on the back edge of the rear fender. Pretty much invisible unless lit. When he used the turn indicators, it was like the 2 LEDs on the right or left end of the device lit up. Maybe Dennis Kirk or Partzilla has such devices in their catalogs.
