Fitting an aftermarket headlight to the Fatbob, which only has a orange and red wire comming out of it , the OEM has black ,white ,orange ,red . Anyway after reading on here about the same problem, of when hooked up high beam is when the switch is in the low beam position,and visa-versa . I straight up connected red to orange and orange to red like they said ! fuggin hell same thing ,high is low and low is high .So twenty minutes later after re-soldering red to red ,orange to orange.........same FUCKEN thing !!  Anyone got any more combo's I can try ? Cheers

Scotty , when you say ''position'' light ,do you mean the parking light ? thanks Mate . Will attack it after work with a test light / multimeter .

It's all good ,thanks for info Scotty. FWIW from the bike to the light, Orange to white & red to yellow
