- Zip Ties Installation: Secure the device to the seat post or frame using the provided zip ties. Ensure it is tightly fastened to prevent movement.
- Bracket Installation: Attach the mounting bracket to the seat post using the screws. Then, slide or clip the device onto the bracket until it locks securely.
- Double-sided Tape Installation: Clean the desired mounting surface on your bike. Apply the double-sided tape to the back of the device and firmly press it onto the bike surface for several seconds. This method is suitable for flat surfaces.
Ensure the device is mounted in a position where the tail light is clearly visible from the rear and the alarm is not obstructed.
Operating Instructions
Tail Light Modes
The smart tail light features four distinct lighting modes, easily selectable via the remote control. Two of these modes are intelligent auto modes.

Figure 2: Smart Tail Light 4 Light Modes. This image displays the four available light patterns: Slow Flashing (intelligent mode), Breathing (intelligent mode), Blinking, and Steady Light.
- Slow Flashing (Intelligent Mode): The light flashes slowly. In intelligent auto modes, the light turns off automatically after 30 seconds of inactivity in dark conditions and turns on when motion is detected.
- Breathing (Intelligent Mode): The light gently fades in and out. Similar to slow flashing, this mode also features intelligent auto on/off functionality based on darkness and motion.
- Blinking: The light blinks rapidly.
- Steady Light: The light remains continuously on.
Auto Brake Light Function
The tail light is equipped with a G-sensor that detects when you brake or slow down. Upon detection, the light will automatically highlight for 2 seconds to alert drivers behind you, significantly reducing the risk of rear-end collisions.

Refer to the product's specific instructions (often involving button presses on the device or remote) to cycle through the sensitivity levels. A higher level means greater sensitivity.
Alarm Volume Adjustment
The alarm volume can be adjusted to 3 different levels, with a maximum output of 113dB.
