Drove ole Toad to a BMW shop to pick up the relay that wuz bad, then back home and replaced it later. Only thang about riding while the relay is stuck (if that is your problem) and the light constantly on is - I'm not sure if the brake light brightness is activated with the brake lever/pedal. You might check that before you go, and depending on how far you have to ride. Good luck.

And I believe it is fuse seven on the left hand side that will cut it off when you are off the bike.

Re: Brake light on with key out

I just replaced my brake light relay on my 04 LT this past saturday for the same problem. I'ts located under the fuel tank. It is yellow & part # is 61366902041. I bought one at Advance Auto BWD Automotive part # R3154. I think this is also a Borg Warner Part #. It was just under $8.00. Three days & about 400 miles later and no problems.

The housing was a little different with out the lock tabs but it fit just fine.

Re: Brake light on with key out

Fuse #1 is switched and provides power ot the brake switches.

Fuse #3 is unswitched and provides power ot the BMU.(Bulb Monitor Unit)

Fuse #7 is switched and provides power to the BMU


Conclusion: Pulling Fuse 3 will probably make the brake light go out when the key is off.
