Review on Stay Safe While Cycling With G Keni Smart Bike Tail Light - Auto On/Off, Waterproof, USB Rechargeable, And Ultra Bright LED Warning Back Bicycle Flashlight! by Todd Roybal

First off I love the function of this brake light. I just wish there were better mounting options. Granted it comes with a clamp for mounting under your seat and a band for mounting to you seat post. In general this would be good. However, I have large hands and this has tiny pieces. It took me 1/2 hours to get it mounted under my wife's seat, dropping the parts many times. My seat has a bar for mounting a saddle bag and therefore I could not install the light there but was able to use the seat post band. Sounds great until you add a bike trunk. My wife is short, her seat is low and a small trunk hides the light completely. I'm tall, my seat is high and I have a big trunk. My light is hidden from any distance. Sadly, there is no easy means, with the parts supplied, to mount this light anywhere else on the frame. It would be great if it came with a bracket that would allow it to be attached to my rear rack.
