Smart Auto Brake Sensing Bike Tail Light USB Rechargeable IPX6-Q0

Ride with clear signals that others can instantly understand. This smart tail light brightens automatically when you brake, helping drivers and riders behind you react faster.

Day or night, your visibility adjusts without effort. The light senses movement and ambient conditions, so it turns on when needed and sleeps when you stop.

This tail light uses a built-in acceleration sensor to detect braking and increase brightness at the right moment. It creates a clear visual signal behind you without needing manual control.

The intelligent system also detects surrounding light and turns itself on when needed. When your bike stays still for 30 seconds, it enters sleep mode, then instantly wakes with vibration so you don’t have to think about switching it on.

With a 250mAh battery and USB Type-C charging, you get flexible use across short commutes or long rides. The included mounts fit seatposts or saddle rails, making installation straightforward in different setups.

Unlike basic lights that stay the same brightness, this one reacts to real riding behavior. That means better awareness, less manual effort, and a cleaner riding experience without constant adjustment.

Stay seen and ride with more confidence every time you brake.
