Review on 🚴 4-Piece USB Rechargeable Bike Taillight Set - LED Bright Bicycle Rear Light Waterproof - Bike Safety Lights Cycling Flashlight - Includes USB Cables by Eddie Rivas

Inexpensive, I tried it. These lights are utterly useless for daytime cycling, winter riding, or anywhere else, but fine for nighttime use with more than one, or maybe carried around as an emergency backup. Fasteners"rubber" are of poor quality and will not last long. Water resistance is good when it's right; I didn't check, I don't know. In comparison, there are better options to choose from.
