have done this mod to probably 20 customer bikes and 12 or more of my own XB's. have never done it to an R model....only S and X platforms.....like yours. NEVER had any complaints....never had any on-coming cars flash beams to indicate they were annoyed or blinded....i like the mod alot.
A FEW SUGGESTIONS: if you haven't i'd strongly suggest replacing the low-beam bulb with either a newer style "super bright" H7 bulb or even better a yellow output H7. the yellowish-glow is a nice attention getter during the day for idiot cage pilots. and when doing this mod you'll find the "harness pin-swap" challenging to say the least sometimes resulting in damaged pin connectors and harness plug. want to avoid that potential catastrophe??? simply splice the yellow wire(low beam +) into the orange wire(full harness +) and you'll have both lights on when switched to high beam with the handlebar switchgear selector switch. DO IT ON THE HEADLIGHT BUCKET SIDE....NOT THE HARNESS SIDE.
