Very encouraging but... I have yet to find anyone who's installed any LED in a K1200RS. Every bike is different, as the ST thread shows, as the AdvRider threads shows. The RS H3 high beam has an oddball socket arrangement which precludes any lamp that has structure past where an H3 would end. I ground the socket on my RS to make the HID H3 fit, and still think it's mostly a kludge. It works but I'm not 100% sure I know why.
Oddly, H7's aren't hard to come by, but... H3 high beams seem to trending towards hens' teeth. I've found a few at significantly lower output than the H7 low beam.
