My 2015 triglide rear brake light switch works fine, when the bike is cold. As the bike heats up the rear brake switch engages the light. It seems that the switch itself is not a problem till the bike heats up.. I havent been able to find any links that address this issue.. Is the switch adjustable? Any insight on this... Ps.. Had full brake service done this spring.. didnt notice any problem till after a 100 + mile ride , now is happening even on relatively short runs.
