Just a thought. I thought they would perform better than incandescent. The reasoning is that from behind at night the FJR is hard to see. I was sitting at light late a few nights ago on a straight, 55mph road and I heard someone squealing violently to a stop. I checked my mirror and he was in my lane, switching to the other lane to avoid hitting me. The car skidded to a stop at an angle and right at the line. I wouldv'e been creamed. It was a kid and his girlfriend in an old Barreta and they looked drunk. They definately drove like they were drunk. I think the best bet for more visability is the 6" light bar over my plate with the "Back Off" Module. I saw something about some wide reflective tape that comes in colors, including black, that lights up bright white when lights hit it. Great for the saddle bags, but I don't run with the bags all the time. From what you guys are saying, the incandescents are fine, you just need a little extra help back there.
