Intelligent Brake Lights
Thanks to a state-of-the-art acceleration sensor and a powerful MCU, the three-stage digital filter algorithm precisely detects when the brakes are applied and automatically switches to brake light mode.
Function
- Automatically switches off after 4 minutes of inactivity and reactivates as soon as motion is detected.
- Detection of a speed reduction, where the brightness is increased up to three times.
USB Rechargeable Battery
The integrated 500 mAh battery requires 3 hours for a full charge and provides 8 to 12 hours of operating time with the included USB cable. Less frequent charging ensures more convenience.
