5. Installation
The YIGER ID040 lights offer flexible installation options due to their magnetic design.
5.1 Direct Magnetic Attachment
If your desired installation surface is metallic (e.g., a metal cabinet, refrigerator), simply place the light directly onto the surface. The built-in magnets will hold it securely.
5.2 Installation on Non-Magnetic Surfaces
For non-metallic surfaces like wood, plastic, or painted walls, use the provided adhesive metal strips:
- Prepare the Surface: Clean the desired installation area thoroughly to ensure it is free of dust, grease, and moisture. Allow it to dry completely.
- Attach Metal Strips to Light: The light has built-in magnets. Place the adhesive metal strips onto the magnets on the back of the light.
- Peel and Stick: Remove the protective film from the adhesive side of the metal strips.
- Mount the Light: Press the light firmly onto the cleaned surface for at least 30 seconds. Ensure a strong bond.
The light can be easily detached from the metal strips for charging or repositioning.

6. Operating Modes
The YIGER ID040 light features a slide switch with four modes:
- OFF: The light is completely off.
- ON: The light remains continuously on, regardless of motion or ambient light.
- AUTO (All-Day Motion Sensor): In this mode, the light will activate when motion is detected, regardless of the ambient light level. It will turn off approximately 20 seconds after motion ceases.
- NIGHT (Dark-Sensing Motion Sensor): In this mode, the light will only activate when motion is detected and the ambient light is dim or dark. It will turn off approximately 20 seconds after motion ceases. This mode is energy-saving for nighttime use.

7. Charging the Battery
The YIGER ID040 light is powered by a rechargeable lithium polymer battery.
- Charging Port: Locate the USB-C charging port on the side of the light.
- Connect Cable: Insert the included USB-C charging cable into the light's port and connect the other end to a USB power source (e.g., computer, wall adapter, power bank).
- Charging Indicator: A red indicator light will illuminate during charging. It will turn green when the battery is fully charged.
- Charging Time: A full charge typically takes approximately 3 hours.
- Battery Life: A fully charged light can operate for 30 to 45 days if activated five times a day, or continuously for 8-9 hours in ON mode.

8. Maintenance
- Cleaning: Wipe the light's surface with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Battery Care: For optimal battery life, avoid completely draining the battery frequently. Charge the light when the indicator shows low power.
- Storage: If storing the light for an extended period, charge it to about 50% and store in a cool, dry place. Recharge every few months to prevent deep discharge.
9. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Light does not turn on in motion sensor mode. | Battery is low or depleted. Incorrect mode selected. Ambient light is too bright (in NIGHT mode). Motion sensor is obstructed. | Charge the light fully. Ensure switch is set to AUTO or NIGHT. Move to a darker area or switch to AUTO mode. Clear any obstructions from the sensor. |
| Light turns on too frequently or unexpectedly. | Sensor is too sensitive or placed in a high-traffic area. Heat sources or air currents triggering sensor. | Reposition the light to a less active area. Ensure the light is not near vents, heaters, or direct sunlight. |
| Light does not charge. | Faulty USB-C cable or power source. Charging port is damaged. | Try a different USB-C cable and power source. Contact customer support if the port appears damaged. |
| Light is dim. | Battery is low. | Recharge the light fully. |
