Operating Instructions
Power and Mode Selection
The light bar features a button for power control and mode selection. There are three primary operating modes:
- MODE 1: Motion Sensor Mode (Green indicator light flashes once) - The light will automatically turn on when motion is detected in low-light conditions and turn off after approximately 20 seconds of no motion.
- MODE 2: Always On Mode (Red indicator light flashes once) - The light will remain continuously on, regardless of motion or ambient light.
- MODE 3: OFF - The light is turned off.
To switch between modes, short press the button. To activate the Always On Mode from any other mode, long press the button for 3 seconds.

Light Color Modes
The light offers three color temperature options to suit different preferences and environments:
- White Light: Bright, cool illumination.
- Warm Light: Soft, yellowish illumination.
- Natural Light: A balanced blend of white and warm light.
To cycle through the color modes, short press the button while the light is in Always On Mode.
Motion Sensor Functionality
In Motion Sensor Mode, the light detects movement within a 10-foot range and a 120-degree angle. It is designed to activate only in dark environments to conserve battery life. The light will automatically turn off after approximately 20 seconds if no further motion is detected.

Troubleshooting
| Issue | Possible Cause | Solution |
|---|---|---|
| Light does not turn on in Motion Sensor Mode. | Sufficient ambient light; battery low; sensor obstructed. | Ensure the environment is dark enough for activation. Charge the device. Check if the motion sensor is clear of obstructions. |
| Light turns off too quickly or stays on too long. | Sensor sensitivity variation; continuous motion. | The sensor has a fixed 20-second auto-off timer. Ensure no continuous motion is within range if it stays on. If it turns off too quickly, reposition the light or ensure the sensor is not obstructed. |
| Light does not charge. | Faulty cable or power source; charging port issue. | Try a different USB cable and power source. Ensure the cable is fully inserted into the charging port. |
| Light output is dim. | Low battery. | Recharge the device fully. |
