Maintenance
Proper maintenance will ensure the longevity and optimal performance of your BrickBling LED Lighting Kit.
- Cleaning: Use a soft, dry cloth to gently wipe away dust from the lights and wires. Avoid using liquid cleaners directly on the electronic components.
- Wire Care: Do not pull or excessively bend the wires, as this can damage the internal conductors. Ensure wires are not pinched by LEGO bricks.
- Storage: If disassembling the kit for storage, carefully disconnect components and store them in a dry, dust-free environment, preferably in their original packaging or a protective container.
- Power Source: Always use a stable 3-5V USB power source. Avoid using power sources with higher voltage, as this can damage the LEDs and circuit board.
