General Installation Steps:
- Prepare Your LEGO Set: Ensure your LEGO Home Alone #21330 set is fully assembled and stable.
- Identify Components: Familiarize yourself with the various lighting components, including lights, connection cables, expansion boards, and power sources.
- Route Cables: Utilize the ultra-slim flat flex cables to route wiring discreetly between LEGO studs and plates. These cables are designed to fit without creating gaps or compromising the structural integrity of your model.
- Connect Lights: Attach individual lights to specific areas of your LEGO set as indicated in the 3D guide. The plug-and-play connectors feature reverse polarity, allowing for easy connection in any orientation.
- Connect to Expansion Boards/Docks: Link multiple lights and accessories to expansion boards or docks to manage power distribution.

Important Considerations:
- Cable Management: Carefully route cables to avoid pinching or excessive tension. The flat design allows them to sit invisibly between bricks.
- Power Source: We recommend powering this kit using a USB Power Bank or a USB Wall Adaptor (for connection to a mains outlet). These power sources are not included.
- Component Compatibility: All components are designed to fit perfectly with LEGO bricks, ensuring a discreet and integrated look.

5. Operating Instructions
Once all lighting components are installed and connected to the power brick, connect the power brick to a suitable USB power source (e.g., USB power bank, USB wall adapter, or computer USB port). The lights in your LEGO Home Alone set will illuminate, bringing the model to life.
Some kits may include Flux Touch Plates or other interactive elements. Refer to your specific 3D installation guide for details on operating these features.

6. Maintenance
- Cleaning: To clean your illuminated LEGO set, gently dust with a soft, dry cloth. Avoid using liquids or harsh cleaning agents directly on the lighting components.
- Cable Inspection: Periodically check cables for any signs of wear, damage, or pinching. Ensure all connections are secure.
- Storage: If storing your set, ensure cables are not excessively bent or tangled. Store in a cool, dry place away from direct sunlight.
7. Troubleshooting
- Lights Not Turning On:
- Ensure the power brick is securely connected to a functional USB power source.
- Check all cable connections to the power brick, expansion boards, and individual lights. Ensure they are firmly seated.
- Verify that the USB power source is providing adequate power. Try a different USB port or power bank.
- Some Lights Not Working:
- Inspect the connections for the specific non-working lights. Re-seat the connectors.
- Check for any visible damage to the cable or LED of the affected light.
- If using expansion boards, ensure the non-working lights are connected to a functional port on the board.
- Flickering Lights:
- This can indicate a loose connection. Re-check all connections, especially at the power source and expansion boards.
- Ensure your power source is stable and providing consistent power.
- Difficulty Routing Cables:
- The flat flex cables are designed to fit between studs. Avoid forcing them. If a cable is difficult to route, try adjusting the surrounding LEGO bricks slightly.
- Refer to the 3D installation guide for specific cable routing suggestions.
