Product details
Description
Brake Sensing + Auto Light + Vibration Detection
During riding, the tail light detects braking through G-sensor changes such as braking or vibration. When braking is sensed, the light automatically switches to maximum brightness for about 3 seconds in any mode to warn vehicles and pedestrians behind. Built-in light and vibration sensors enable automatic on/off: the light turns on in low-light conditions, switches off after about 30 seconds of being stationary, and reactivates instantly when vibration is detected.
(*Please refer to images for supported modes.)
Multiple Lighting Modes with One-Click Control
The rear light features a high-transparency PC lens and bright LED for soft yet clear illumination with wide visibility. It supports free switching between lighting modes using a single button:
- Slow Flash
- Breathing Flash
- Burst Flash
- Always On
Simple one-click operation allows quick mode changes while riding, with a memory function that recalls the last used mode.
