Bulb? Short or open in wire? Loose connection? Sending unit not operating? I can't tell you what's wrong but I can tell you how to slove it: use a multimeter and test.

Hows your wiring into the tail light assembly? Have you checked the bulb itself? I have seen where bulbs will get a little moisture and start to corrode then lose electrical contact.

Hey Steve, check your front brake! This happens to me now and again, too, and it always is my front brake lever.

Are you getting an error message or light come on on the dash. I had this happen and the error light came on. The light just confirmed something was wrong but did not tell me what. Good ole fashion look-see saved the day. It wasnt electrical per se but the wires came loose on the *** end and they rubbed on the rear tire. Simple fix if so.

Check:

1 wiring under rear fender
2 wiring harness under seat
3 fuses

Clean & lube connections lightly with dielectric grease.

Start easy first - check the bulb. Then check your connections. Then check the wiring for obvious problems (like a broken wire), then check the switches.
