Each set includes two compact light bricks that automatically cycle through red, yellow, and green flashes, making them a straightforward addition to any street scene or intersection layout. They come with two USB connectors and connection terminals, so you can power them via a standard USB port or integrate them into a larger wired setup. The concealed wiring keeps the build clean, and the clips fit standard Lego bricks for easy placement.\u003c\/p\u003e\u003ch2\u003eHow Do These Traffic Lights Work in Your Brick City?\u003c\/h2\u003e\u003cp\u003eOnce connected to power, the lights run through a repeating sequence: red, then yellow, then green, then back to red. You don't need to press a button or set a timer—they just keep cycling. This automatic flashing mimics real traffic signals and adds movement to an otherwise static build. Because the wiring is hidden along the base, you can set them on roads, sidewalks, or raised platforms without visible cables spoiling the look.\u003c\/p\u003e\u003ch2\u003eWhat's in the Box and How to Connect?\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eContents:\u003c\/strong\u003e Two pre-assembled traffic light bricks, each with an attached USB cable and connection terminals.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Options:\u003c\/strong\u003e Plug the USB end into any standard USB charger, power bank, or computer port.
