Review on 🚴 Enhance Your Safety with BESTSUN USB Rechargeable Bicycle Tail Lights: Bright LED Bike Cycling Safety Zone Tail Light with Dual Red Safety Lines for Cycling and Hiking by Jeff Sprunk

Works well. It has an integrated battery charge controller so the lithium-ion battery inside will never overcharge or fail. The LEDs blink and shine very brightly. Laser stripe pointers are disappointing. Although they started out at the same brightness, one quickly became much dimmer than the other. Both lasers appear to be wired in parallel with the board, so I'm assuming the one with the lower internal resistance will run brighter. Lasers are not visible in daylight. Not at all. From a full charge, the battery lasted over an hour with everything on. The plastic lens snaps into place and can be pulled out of the lamp with your fingernail. Mine is fairly reliable, but quality varies, and if you're worried about the lens falling off, a dab of glue or a piece of tape will stay in place. The bracket is cheap plastic and will likely break if you bump into something. But it should be enough for normal driving. I replaced the supplied mounting nut with a lock nut. I suspect a lot of people lose these headlights because the bolt flies out of the nut due to vibration while driving.
