Review on Ultimate Safety: CXWXC Smart Bike Tail Lights - USB Rechargeable, Waterproof with Ultra Bright LED Brake Light for Cycling Riding by Domonic Roberts

I've tested over 30 different bike rear lights. I ride my bike and find darkness/fog visibility to be my biggest safety concern. i'm lazy too While I've reviewed brighter and larger headlights, as well as headlights with turn signals and crazy color shows, these smart bike lights are always the ones I have at the end of the week. They are reliable, easy to use and just work. In my case I can set them to Auto and they will turn on when I get on the bike and turn off when I arrive at my destination. They flash when I'm driving and come on solid when I'm braking. These are all ticked boxes. I love that it has easy mounting options for the bike rack and bike seat rails. I use both configurations, but in this case the seat I'm testing doesn't have rail space. Ten seconds to attach the tape to the post and you're done. Normally I only have to charge them every two weeks. I ride 12 km every day.
