6.7 Smart Auto ON/OFF
The tail light features intelligent light and motion sensors:
- In Slow Flashing and Breathing modes, the tail light automatically turns off after 30 seconds of inactivity in dark environments. It will turn on again when motion is detected.
- In bright environments, the tail light automatically turns off to conserve power.
- If you require the tail light to be on during daytime, select Fast Blinking or Steady Light modes, as these modes do not have the smart auto ON/OFF function.
