There seems to be a part missing from the rear of the head light, the bulb is there and to spade connectors off the wiring harness that is behind the light, what part is missing I assume some sort of connector, any ideas where i can get one from.

Any help much appreciated.

Been down that road too there should be a double wire live& earth from that connector on the harness to the headlight bulb it's about 4 inches long crappy connectors onto the bulb rot out and it ends up not working. Best suggestion is find a dealer who sell new bikes with lights stripped out.. he probably throws this in the bin. hope this helps

will try BVM see if they have anything
