Turns night into day
I just got mine tonight, installed it and took it for a test ride. (2016 Indian Roadmaster-which comes with a factory LED headlight). All I can say is WOW. I'm not sure the overall light intensity is all that much brighter-but there are no dead spots, the beam is far wider and the adaptive function...seems like magic. A road I commonly take at night is bunch of tight, twisty, 20-40 MPH curves, with a bunch of hills and dips. Oh, and a rock face on one side and river on the other. It's about a 8-10 mile stretch (and a lot of fun in the daylight) without a single street light (and few houses). With the stock headlight, I found it downright scary. Every time I banked into a curve the abrupt cutoff of the light beam left curves utterly black-it's like riding by brail-no idea the sharpness of the turn (and I've put a bunch of time trying to dial in the adjustment). Making right turns off a dark country road is the same way-nearly have to stop and turn the fairing to see rather than lean into the turn and ride through it. Hills/dips in the road left huge dark areas, and of course the normal dark band below the high beam "patch". Oh, and at best the beam pattern is pretty narrow-forget seeing critters off the side of the road. I found passing cars coming the other way on dark country roads bad as well-the low beams are aimed so low (when the highs are adjusted to be functional) that it's like being blind when someone is coming the other way. Tolerable in town and not bad on wide, straight, level roads-none of which describe North Idaho.

With the adaptive-world of difference. Light everywhere with no dark, blind spots. Coming into the turn the adaptives kick in (on top of the much more effective high beam) and throws light around the corner. The first couple of curves I was taken back a bit-it seemed like someone was coming the other way the way the corners lit up. Curves that had me creeping around before now I could take comfortably at 40mph or better. I could see deer (aka fur-bearing terrorists) out in the fields when driving. Turning off the paved country road onto my dirt road was always an adventure-nearly impossible to see the turn until on top of it, and again, nearly have to stop to make the turn. Now-it's like daylight-no issues seeing the road coming up to it, and seeing around the turn was a non-issue. And the low beam issue is much better-I felt I could ride quite safely on just low beams at a decent speed. Coming over hills no longer left a huge black hole (and I think I can get this better-I think it's set a bit high). Oh, did I mention that it was raining this time and my visor was fogging? Still could see far better than with the stock bulb on a dry night.
Paying the price was painful (and I'm a bit financially challenged-as well as cheap) so it took a bit to convince me. As of now, I have to say, worth the money. I honestly think that with it I might have avoided the deer I tagged last fall with this light. That happened when I had to drop to low beam due to a car coming the other way and a deer ran between us-never even saw it till it hit my fender. At least now there is a fighting chance against zombie bambis.

After a few more days riding, I am even more impressed. Makes a huge difference on tight, twisty roads that abound with wildlife. If I were traveling more flat, straight roads, I'd look as something different and less expensive. But on a twisty road, this thing rocks.

Is there a difference in the amount of reflected light between the black and chrome?
A shopper on Mar 30, 2018
BEST ANSWER: No difference. Since all the LED’s are behind projector lens. The housing doesn’t play a part in light distribution.
I have a 2014 street glide special, is the mount needed? The two options are with mount and with out mount.
