With this kit, you get everything you need to add head lights and tail lights to your vehicle! This kit is designed to fit virtually any vehicle shorter than 12 inches long. Each light comes preinstalled inside of an authentic LEGO piece. The wire comes out of the side of the piece, allowing it to attach to any brick stud. Each light has about 6 inches of wire will connect to a central power brick. The power brick can hold up to 11 lights which means you can add more of our plug and play lights if you would like more than just head lights and tail lights.
