It works!!!! Thanks a million. Only thing is, the switch on top of the light-bulb just rotates around and around and doesn't do anything or engage with anything, never has since I have owned the bike. Yet when you mentioned it I went out and played with it and discovered if I pull up and push down on the headlight switch it turns disconnects the tail light from the battery circuit. So now I got it figured out and everything is working smoooooooth. Thx, Chris.
