Just put the new HD LED headlight and passing lamps on my bike. Very nice and very bright. Was out for a 400km run this weekend on a nice sunny day with 4 of my buds. To a man/woman they all said when i was behind them I was very bright. I thought they were talking about me but apparently it was the lights. I'll be leaving them on.
Mine are always on, day or night. Rather be seen and I like the way the low beam and the aux. lights illuminate the road at night better than the hi beam. It seems that the majority of riders that I pass on the road with aux lights have them on during the daytime as well.
Always off. Same with the sound system. Should have bought a RK and added the trunk. Lots of crap on the Ultra that I do not want. Now HD is thinking about XM and GPS.
