Knog

I use this light as the main light for road biking, fixed gear, and gravel cycling. My secondary light is a Cygolite mounted with a gopro mount on my helmet. The Knog is pretty bright, though it definitely seems brighter offroad. Compared to the Cygolite, the Knog's light is a little bit on the yellow side, so that makes it wash out a little on the road. If the light is used by iteself, this isn't as noticable. I previously had a Light and Motion light (they went out of business) which has a much wider beam, but I can't complain too much. The usb C charging connection is also really nice as it charges quickly and is not a keyed connector.

This a good light to be seen, but not to see in dark conditions. It has a 180-degree view, but the light isn't focused so you can't use it for night riding. That's fine as I bought this to be seen. The only criticism I have is the battery. As it's winter, I haven't used this on a long ride, but it seems like 5-6 hours is the max battery life on even lower setting. It also takes a long time to charge. So don't use it at night and don't expect it to last on a long ride and it's fine.

This is an update to my previous review, where I noted the primary weakness of this product: it's clasp. I wanted to note that Knog made good on its warranty, by sending me TWO replacement clasps, so kudos to them. My plan going forward is to always remove this headlight from the handlebar whenever I'm not actually riding the bike. This way, the pressure on the clasp will be minimized and I think I may get a reasonable span of use for this product. Perhaps in a future iteration of this light they can improve the mechanism of attachment.

Several reviews said the lights died after a week or two, just like mine. I took them off and felt like a chump. But then I wondered if that's the only way these simple yet elegant lights have to tell us they need to be charged. I plugged them in to USB-A chargers. They gave the single bright LED message. I checked them often, to make sure they weren't getting hot, ready to burst into flames or something. But after several hours, the BRIGHT LED was off. I pressed the tiny power button. The light came on in "see me" mode. It let me select a blink pattern. They've been working for weeks now. I'm one with these little things. I mounted the white one on the bottom of my left fork, and the red one at the bottom of the left seat stay. Pretty cool looking imho. These are easily worth the pittance BTD charges for them.
