Powering your Light My Bricks 75349 Captain Rex Helmet light kit is straightforward. First, make sure you have a 5V USB power source, such as a power bank, a wall adaptor, or a USB to AA pack (sold separately). The kit includes a USB power cable, but the power source itself is not included. Next, use the included 30cm connecting cable to link the lights to the expansion boards; gently insert the connectors to avoid any damage. Then, connect the USB power cable to your chosen 5V power source, ensuring it provides the correct voltage. To check everything is working, use the Power On Test symbol described in the Light My Bricks installation guide. If you run into any issues, consult the troubleshooting section of the user manual for solutions.
