Sorry, but the camera on my phone isn't top notch, so I didn't get the best pictures of your headlamp choices, but here they are. From right to left, we have the Harley Daymaker, Kuryakyn (Trucklite) Phase 6, Kuryakyn (Trucklite) Phase 7, and stock.
IN THE DARK
The 3 of us with LED's rode home in the dark tonight and all 3 are awesome. This was the first time I rode with anyone at night that had the Harley LED's and WOW! are those things bright. Riding in front of him, I really couldn't even see the passing lamps at night. The headlamp is just overpowering. From riding behind him, I could see a very distinct area that was lit up like a studio ready for a photo shoot. That area extended about the same as my Phase 6 lamps, which blows away the stock lights. I was very impressed at how wide the spread of the beam was. We rode the highway home, and there is a concrete barrier between sides of the highway. Riding in the right lane of the 2 lanes on our side of the barrier, he still had that barrier pretty well lit up. Off the right side of the road, I made the decision quickly to watch in his light area for deer on the side of the road. I was fine with my my lights capabilities for lighting up the side of the road before, but now I am realizing how much more is possible. As far as this aspect goes, the Phase 7's are better than my Phase 6's, but still not in the same league with the Harley's. Between the Phase 6 and 7, I think the Phase 6 has the advantage directly in front of the bike, and the Phase 7 has the advantage with light off to the sides...but the Harley lamps win in both categories.
IN THE DAYLIGHT
Phase 6...very distinct lighting that allows you to recognize the bike behind you from a very long distance and hard to miss seeing the bike.
Phase 7...very distinct lighting that allows you to recognize the bike behind you from a very long distance and hard to miss seeing the bike.
Harley...from looking in my rear view mirror, I found that if I looked in one mirror, I could see the lights well and they seemed to have somewhat of a yellow-green tint (but that may change depending on the sunglasses you have on), and if I looked in the other mirror I found the lamps to be almost to the point of disappearing. I'm not sure why there was such a huge difference with such a small change in viewing angle, but I mentioned it to one of the other guys and he confirmed that this is what he saw also. I'm guessing that these lights aren't seen quite as well from angles in the daylight, but I'd have to get a look at him head on coming the other way down the road to solidfy my opinion on that aspect of operation.
My overall opinion, as well as the others' opinions, are that the stock lights shouldn't even be legal after having our LED's. Having the LED's makes for a much more confident and thus more relaxed ride at night.
