4. Operating Instructions
The light features a multi-function switch to control its modes and brightness.
4.1 Changing Operating Modes
Single press the switch to cycle through the following modes:
- Mode 1 (AUTO Mode): The blue indicator light illuminates. In this mode, the light will automatically turn on when motion is detected within 13 feet in sufficiently dark conditions. It will turn off after approximately 20 seconds of no activity.
- Mode 2 (Always On Mode): The indicator light turns off. In this mode, the light remains continuously on.
- Mode 3 (Always Off Mode): The light is completely off.

4.3 Charging the Battery
The light is equipped with a built-in 1100mAh rechargeable battery and a Type-C charging port.
- When the battery is low, the indicator light may flash or the light output will diminish.
- Connect the provided Type-C charging cable to the light's charging port and to a standard USB power source (e.g., phone charger, computer USB port).
- During charging, the indicator light will be red.
- Once fully charged, the indicator light will turn off.
A full charge typically provides approximately 5 hours of use in Always On mode or up to 2 months in AUTO mode, depending on activation frequency.

5. Maintenance
To ensure the longevity and optimal performance of your YEELIGHT Under Cabinet Motion Sensor Light, follow these maintenance guidelines:
- Cleaning: Wipe the light's surface with a soft, dry cloth. Do not use abrasive cleaners or solvents, as they may damage the finish or electronic components.
- Battery Care: For best battery life, avoid completely draining the battery frequently. Charge the light regularly, especially if it will be stored for an extended period.
- Environment: Use the light in indoor environments only. Avoid exposure to extreme temperatures, high humidity, or direct water contact, as it is not water-resistant.
- Sensor Area: Keep the motion sensor clear of obstructions to ensure accurate detection.
6. Troubleshooting
If you encounter issues with your YEELIGHT Under Cabinet Motion Sensor Light, please refer to the following common solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Light does not turn on in AUTO mode. | Insufficient darkness; no motion detected; battery low. | Ensure the environment is dark enough. Move within the sensor's range (13 feet). Charge the battery. |
| Light stays on constantly in AUTO mode. | Constant motion in sensor range; light sensor malfunction. | Ensure no continuous motion is present. Try moving the light to a different location. |
| Light does not charge. | Faulty cable or power adapter; charging port issue. | Try a different Type-C cable and USB power adapter. Ensure the cable is fully inserted. |
| Short battery life. | Frequent activation in AUTO mode; used in Always On mode; aging battery. | Reduce frequency of motion detection if possible. Note that Always On mode consumes battery faster. Ensure full charge. |
| Light is not bright enough. | Brightness setting is low; battery low. | Adjust brightness in Always On mode (see Section 4.2). Charge the battery. |
If the problem persists after trying these solutions, please contact customer support.
