6. Troubleshooting
If you encounter issues with your light kit, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Lights do not turn on. | No power, loose connection, or faulty component. | Ensure power source (USB adapter or batteries) is working. Check all connections are secure. If using batteries, replace with fresh ones. |
| Lights are flickering. | Unstable power supply or loose connection. | Verify power source stability. Check all wire connections for tightness. If using batteries, ensure they are fully charged and properly inserted. |
| Dimmer function is not working. | Button not held long enough, or component issue. | Ensure you are pressing and holding the button to adjust brightness, not just tapping. If the issue persists, contact customer support. |
