7. Maintenance
To ensure the longevity and optimal performance of your BrickBling LED Lighting Kit, follow these maintenance guidelines:

- Storage: When not in use, disconnect the power source and store the light kit in a dry, cool place, away from direct sunlight and extreme temperatures. If using batteries, remove them before long-term storage to prevent leakage.
- Handling: Handle the wires and LED components with care to prevent bending or breaking.
8. Troubleshooting
If you encounter any issues with your BrickBling LED Lighting Kit, please refer to the following troubleshooting steps:
- Lights Do Not Illuminate:
- Ensure the power source is correctly connected and functional. If using USB, try a different USB port or power adapter. If using batteries, check if they are fresh and inserted with correct polarity.
- Verify all cable connections between the LED components and the power supply are firmly seated.
- Inspect for any visible damage to wires or connectors.
- Lights Flicker or Are Dim:
- Check for loose connections. Gently press on each connector to ensure a secure fit.
- Ensure the power source provides stable power. If using batteries, they might be low and need replacement.
- Only Part of the Lights Work:
- Carefully inspect the connections for the non-working section. A single loose connection can affect a segment of lights.
- Refer to the online video instructions to re-trace the wiring path for the affected section.
