rear brake switch
 

I saw on here some time ago a list of parts which stated and this is a bit of a guess that you can use a switch from a car maker cant remmember the make plus various other parts for 900ss 94 vintage any advise please thanks.......

http://www.users.waitrose.com/~paso/parts.htm is the address of the Ducati Parts Interchangeability List but checking there I can't see any mention of rear brake light switches.

what's a "rear brake"?
