Review on 🚴 XOSS LEADBIKE LD09 Rechargeable Ultra Bright Smart Bike Tail Light - 6 Light Modes, 35 Hours Waterproof, Fits on Any Road Bikes - Enhance Visibility and Safety by Jon Brazil

I love this rear light for my mountain bike converted to an e-bike. The braking functions worked flawlessly in both manual and automatic modes. Switching modes and adjusting lighting settings is easy by following the instructions. I saved the picture of the box as these are the only instructions you will receive. The XOSS Leadbike flashlight comes with a variety of mounting options. I was able to disassemble the included seatpost mount and attach it to a flat post, which worked great for me since I attached a bag under the seat (see picture). I mainly use the light in manual mode, so it flashes during the day while I'm driving (the auto brake function works great in this mode). My only complaint is that Auto mode requires both motion and darkness for the lights to come on, except when braking. I like to flash my tail light when driving during the day. This flashlight is quite bright, charges quickly and provides many hours of use without recharging. I highly recommend this taillight.
