LED's and HID's are all the rage these days, but is that ultra white light actually the best at letting your eye and brain, working together, see and interpret as much of what is out in front of you as is possible... to pick out as much detail and etc as possible? Curious based on personal experience. Through most of 2016 I had a motorcycle with LED lo and high beams, Ducati. They were well setup with good cutoff and throw but there was always a feeling of... I don't know... weirdness or something as far as how it actually lit the road and road shoulder area. Prior to that bike I'd had a earlier model Duc with LED lo beams but halogen high's. Flicking on the high beams always seemed to impart some manner of "relief" for my vision for lack of a better term. Now I've got an old school bike with dual side by side halogen headlights. While it's not as eye catching to oncomers in traffic it seems like I can actually discern the night road and road shoulder better than before. Some of this could be due to my age 54, because our night vision acuity and contrast discernment decreases with age. Also on a bike, the sag i.e. how the bike sits is relevant to head light aim and for this comparison all bikes' suspensions were dialed in okay. This has to be due to the color temp differences.
