Troubleshooting
If you encounter issues with your LED strip lights, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Lights do not turn on. | No power, loose connection, blown fuse. | Ensure the car charger is fully inserted into the cigarette lighter. Check all cable connections. Inspect the fuse in the car charger and replace if necessary. |
| App cannot connect to the lights. | Bluetooth off, app issue, interference. | Verify Bluetooth is enabled on your phone. Restart the app and try again. Ensure no other Bluetooth devices are interfering. Try restarting your phone. |
| Lights are dim or unevenly lit. | Fiber optic not fully inserted, insufficient LED emitters for length. | Ensure the fiber optic cable is fully inserted into the LED light source. If the length is very long, consider adding an additional LED light source at the end of the fiber optic for better brightness. |
| Lights flicker or change colors unexpectedly. | Loose connection, power fluctuation, app glitch. | Check all connections for tightness. Ensure your car's power supply is stable. Restart the app and the lights (by unplugging and replugging the car charger). |
