A8Pro Electronic Tail Light with Built-In Horn

The ROCKBROS Smart Bike Tail Light acts as your invisible guardian on every ride. With a convenient remote, you can switch modes instantly and take full control in busy city streets or complex road conditions. Its 115dB high-frequency horn pierces through ambient noise, alerting others up to 100 meters away. In smart mode, the light automatically responds to motion and ambient light, conserving energy while keeping you visible.

Compact yet powerful, it provides all-around protection for safe daytime and nighttime cycling. Features Handlebar Remote Control – Switch modes easily without taking your hands off the bars. Four Brightness Levels & Flash Mode – Short press for steady light, long press to cycle through high/medium/low brightness or flashing. Dual Light & Vibration Sensors – Automatically adjust for day/night and motion, conserving energy while keeping you visible. Dual-Function Horn – Gentle alert for pedestrians or anti-theft alarm triggered by sudden shocks. 700mAh USB-C Rechargeable Battery – Fast charging, hours of reliable use included.
