OLIGHT BS 100 Bike Tail Light, 100 Lumens and 260 Degree Visibility Bicyle Rear Lights, 1000m Viewable Range, Type-C Rechargeable Break Sensing Taillights, IPX6 Waterproof for Road and Urban Cyclists

This thing kicks out the light. Multiple modes are very clever and easy to use. Has some sort of inertia sensor or gyroscope to sense braking and serve as a brake light which I didn’t see advertised and is very slick. Battery life impressive. The provided mount is also quality and well done, it does have an angular surface intended to account for seatpost angle which makes it not ideal for using horizontally on the back of a rack unfortunately.

Great red light. Can pick from different settings and the handy mount that snaps onto the seat was a plus.

Love this light - it's bright, has a few functions, and has great battery life. I LOVE that it twists and pulls off the base for easy charging! That feature is super handy and works great.My only gripe is that it has the silicone band mount to put it on the bike, and those sometimes wear down and break. So I'll be keeping an eye on that, and I wish there was an option for a different mount. But so far so good, it does mount securely and works perfectly.

I wanted a red tail light that could catch peoples attention and I was not disappointed. This light is very bright and makes it even better with the motion sense and different modes. The battery lasts a few hours but even when it’s dying it still stays lit so you’re not left in the dark. Mounting is very easy and removable for charging is a breeze. Reattachment is just as easy and secure.

I purchased this item less than a month ago. It arrived perfectly. I wrote a nice review since the light was bright and it looked it was going to be a grat product.After using two weeks the light one burned completely. I use it on my motorcycle to have som auxiliary lights for protection. WHen I needed them the most under heavy rain and at night they stopped working.Do yourself a favor and walk away from this product.

Works as designed. Good visibility.

I have had a few Olight tail lights for my bike. I didn't like that when I had to charge it I had to undo the whole tail light from the seat post, and then fumble with the rubber spacer potentially losing it and then finally charge them via micro-usb.When I saw this was available, I swapped it out and was delighted on the mounting options. The light itself twist locks onto the mount and so easy to throw in my pocket, charge and pop back on the bike when I go back out for a ride. This is similar mounting to some of the Olight headlights for bikes and I'm very happy with it so far. I might actually pick another one up for my other bike since it is so easy to mount and unmount as well as charge up.

Very small, lite weight, good brightness, best of all charges with USBC
