WEST BIKING W3 Waterproof Bicycle Rear Light with Brake Sensor
This smart bike tail light is for the urban commuter or weekend rider who wants to be seen and stay safe after dark. While many lights focus on brightness, this one adds a layer of proactive protection with its brake sensor, turning a routine ride into a more secure experience.
The brake sensor activates instantly when you slow down, flashing brightly to alert drivers behind you before they even react. You get a clear warning that your light is working, with a noticeable change in pattern that cuts through traffic noise. It mounts easily to your seat post and pairs with Alexa for voice-controlled on/off, so you can focus on the road. Waterproof design means it handles rain or splashes without a hitch, keeping you visible in all conditions.
