4. Installation
The M6 light supports both standard handlebar mounting and suspension (front-to-back) mounting to adapt to various bike models.
4.1 General Handlebar Installation Steps
- First, install the fixed buckle onto the bike light.
- Choose a suitable location on your handlebar and install the mounting bracket.
- Fix the bike light to the buckle of the bracket.
- Rotate the bike light 90° clockwise to secure and complete the installation.

4.2 Suspension Installation Steps (Front-to-Back Conversion)
This method allows the light to be mounted underneath a bicycle computer bracket for a cleaner setup. (The bicycle computer extension bracket is a shooting prop; please purchase separately if necessary).
- Remove the standard buckle from the light and install it to the reverse side to enable front-to-back conversion.
- Install the suspension mounting bracket to your existing bicycle computer bracket.
- Locate the desired position and install the bike light onto the buckle of the suspension bracket.
- Rotate the bike light 90° clockwise to complete the installation.

5. Operation
The M6 features intelligent dual-mode control and a digital display for ease of use.
5.1 Button Functions
- Single Click: Switches between light gears (Low → Medium → High → SOS).
- Double Click: Toggles between Smart Mode and Manual Mode.
- Press and Hold (1-1.5 seconds): Turns the light ON or OFF.
- Unlock Factory Lock Mode: Press the button 6 times within 10 seconds. The main light will flash twice to confirm.

5.2 Light Modes
- Factory Setting: The light is in lock mode by default. It can be unlocked by connecting the Type-C charging cable or by pressing the button 6 times within 10 seconds.
- Smart Mode: Features smart start-stop functionality. After 1 minute of inactivity, the light enters a low beam power-saving mode. After an additional 30 seconds of inactivity, the lights automatically turn off. Touch the vehicle or detect vibration to automatically turn on the lights. Intelligent light induction automatically turns off the lights during the day or in bright places, and automatically turns on the lights in dark places or when vibration is detected.
- Manual Mode: The light remains on until the battery is depleted or it is manually turned off. Intelligent light induction and intelligent start-stop functions are disabled in this mode.

6. Charging and Battery Precautions
6.1 Charging
- It is recommended to use a USB power adapter for charging.
- Avoid charging in direct sunlight or in a car where temperatures can fluctuate significantly. Charge within an ambient temperature range of 5-40°C.
- Ensure the charging plug is free from foreign objects or debris.
- The product may not be able to charge if your PC is in sleep mode.
- Always unplug the USB cable once charging is complete.

6.2 Battery Precautions
- Do not store the light in places with high temperatures or direct sun exposure. Charging, discharging, or storing at high temperatures will prematurely deteriorate the rechargeable battery.
- Unplug the light from the charger once charging is complete to avoid long-term charging, which can reduce battery life.
- If the lighting time significantly reduces even after full charging, it indicates that the rechargeable battery life has expired and may need replacement.
6.3 Smart Temperature Control & Low Pressure Protection
The device incorporates a smart temperature control circuit. If the temperature of the light board is detected to be overheating, the brightness of the lights will be intelligently reduced to prevent damage. When the battery reaches approximately 10% remaining charge, the lights will enter a low-voltage mode. For about 30 seconds, the lights will flash 3 times, indicating a low-power state, and the brightness will be reduced to approximately 40 lumens. In this low-voltage mode, the battery life is approximately 120 minutes.

7. Maintenance
- Regularly check that the lamps are firmly fixed to the bracket.
- To clean the lamps or parts, wipe with a clean water or a soft cloth stained with mild soapy water. Do not use harsh chemicals or abrasive materials.
- For long-term storage, please charge and discharge the battery regularly (recommended once every 3 months) to maintain battery health.
8. Troubleshooting
- Light not turning on: Ensure the light is not in factory lock mode. If it is, unlock it by connecting the Type-C charging cable or by pressing the button 6 times within 10 seconds. Check battery level.
- Light unexpectedly turns off or dims: Check the remaining power on the digital display. The light may enter low-voltage mode or reduce brightness due to smart temperature control.
- Battery not charging: Ensure the USB power adapter is functioning correctly and the ambient temperature is within 5-40°C. Check that the charging plug is clean and free of foreign objects.
- Reduced battery life: Avoid charging/discharging/storing in high temperatures. If battery life is significantly reduced, the battery may have reached the end of its lifespan.
9. Safety Precautions
- Always pay attention to the remaining power displayed on the screen and charge the light regularly to avoid unexpected power loss during rides.
- When operating the switch, stop your bicycle first to prevent accidents.
- When using the lights for a long time, the lamp body may become hot. Do not touch the lights directly to avoid burns.
- Keep this product out of the reach of children.
- Do not aim the light directly at your eyes or the eyes of others when turning it on, as the high brightness can cause temporary vision impairment.
