Connect the provided USB charging cable to the Micro USB port on the light and to a 5V/2A power source (e.g., computer USB port, wall adapter, power bank). A full charge typically takes 3 hours. The light is designed for a standby time of up to 90 days and a riding duration of up to 50 hours on a single charge, depending on the mode used.
4.2 Mounting the Rear Light
The A8 Pro offers a dual mount system, allowing installation at either the saddle rail or the round seat post. Choose the appropriate bracket for your bicycle.
Saddle Rail Mount:
- Attach the saddle rail bracket to the saddle rails using the provided screws and Allen key.
- Slide the A8 Pro light unit onto the bracket until it clicks securely into place.
- Adjust the angle of the light for optimal visibility.
Seatpost Mount:

4.3 Remote Control Pairing and Initial Setup
The remote control for new products can be used after charging activation of the main light unit. To set the alarm function:
- Press the 'Lock' button on the remote control.
- The light will emit three 'Beep' sounds and flash three times.
- The alarm will be set after 3 seconds.
5. Operating Instructions
5.1 Power On/Off and Lighting Modes
Press the main button on the rear light unit to power it on or off. Short presses will cycle through the available lighting modes:
- Auto Fast Strobe: Rapid flashing mode, automatically adjusts based on light conditions.
- Breathing: Pulsating light mode, automatically adjusts based on light conditions.
- Manual Pop Strobe: Constant rapid flashing.
- Steady: Constant solid light.
5.2 Intelligent Sensing
The A8 Pro features intelligent light sensing technology. When in Auto Fast Strobe or Breathing mode, the light automatically senses the riding environment:
- In bright conditions (daylight), the lights will dim or turn off to conserve battery.
- In dark conditions (night, tunnels), the lights will brighten automatically.
- If no vibration is detected for 30 seconds after riding, the light will automatically turn off.
5.3 Automatic Braking Light
The A8 Pro is equipped with an intelligent induction brake system. When the bicycle brakes and decelerates, the taillight will automatically switch to high brightness for 3 seconds. This provides a clear and immediate warning to following traffic, significantly enhancing safety.
5.4 Anti-theft Alarm Function
To activate the anti-theft alarm, press the 'Lock' button on the remote control. The light will confirm activation with three 'Beep' sounds and three flashes, then the alarm will be set after 3 seconds. If the bicycle is moved or tampered with while the alarm is armed, a loud 115dB siren will sound to deter theft.
To cancel the alarm, press the 'Unlock' button on the remote control. The light will emit a single 'BEE' sound and flash to confirm deactivation.
5.5 Wireless Bell / Remote Call
The remote control also functions as a wireless bell or remote call feature:
- Short Press: One short press of the bell button on the remote will cause the bell to sound three times and the light to flash three times. This can be used to locate your bike or alert others.
- Long Press: One long press of the bell button will cause the bell to sound three times and the light to flash three times, followed by the light staying on for 3 seconds and a continuous long bell sound. This provides a more prominent alert.
The A8 Pro features an acoustic cavity structure, delivering a loud 105-108dB wireless bell with stronger penetration for effective signaling.
6. Maintenance
