Intelligent Induction Brake Warning Light Bicycle Tail Rear Light with Auto Brake Sensing
For cyclists who ride in traffic or low-light conditions, this smart tail light keeps you visible and safe. It's perfect for commuters navigating busy streets or evening riders who want to be seen by drivers.
While most bike lights focus on brightness, this one adds intelligent safety. The auto-brake sensing feature alerts drivers behind you when you slow down, giving you extra peace of mind during sudden stops. The mic picks up subtle changes in your speed to trigger the warning flash.
With six lighting modes and three brightness levels, you can customize it for any ride. The IPX6 waterproof rating means it handles rain without issues, and the 45° adjustable base prevents glare for following traffic. USB charging provides about 20 hours of battery life, so you can ride confidently without frequent recharges.
