Got Corrected by Genie Blinkerguys ,
Found this for BMW bikes
note – BMW is all over the map on tail and brake.  Especially on single wire tail lights. 
tail – gray w/black stripe OR  blue w/gray stripe OR black w/gray stripe OR red/yellow/gray
brake – yellow w/gray stripe OR gray ...

I have a 2008 RT and a 2005 BMW R1200GS and I am installing tail blinker running lights
Can someone look at this and tell me if it makes sense

I have 5 wires coming from tail harness
Brown goes to stop and blinkers
Blue White go to one blinker
Blue black go to other blinker
Grey red stop light ...
