You can use them to build imaginative light creations and you can also use them to light up your own collection of building blocks. What is a house without lights, a car not able to blink or a lighthouse with…well just dark bricks? Light STAX comes in a wide range of both solid and transparent colors. They work with and without wires and have multiple lighting modes. Just imagine the possibilities.
