- For models with wireless connection features, ensure the roof and floor sections are properly aligned and seated for the lights to activate automatically upon connection.
- This feature reduces the need for visible wires between major modular sections of the LEGO model.
5. Operating Instructions
5.1. Powering On/Off
- Connect the USB cable from your light kit to a compatible 3-5V USB power source (e.g., power bank, USB wall adapter, computer USB port).
- The lights should illuminate automatically once power is supplied.
- To power off the light kit, simply disconnect the USB cable from the power source.
5.2. Remote Control Operation
Video 5.1: This video illustrates the use of the remote control to adjust lighting effects, brightness, and turn lights on or off for different sections of the LEGO Home Alone house.
- If your kit includes a remote control, use it to adjust brightness levels, change lighting effects (e.g., steady, flashing, pulsing), and control different light groups independently.
- Refer to the remote control's specific instructions (usually a small leaflet included with the remote) for detailed button functions and pairing procedures.
- Ensure the remote control has working batteries and is within range of the light kit's receiver.
