This treetop star decoration changes color in unison with the lights on your tree. For use only with artificial Christmas trees that are pre-lit with LED lights, it includes an extra cone end connector for hassle-free installation. It features low-voltage LED bulbs that are energy-efficient and eco-friendly. Made from plastic, this star comes in clear with 10 color LED lights with 10 light functions. It measures 11" tall and 8" wide, so it makes a statement while not overwhelming your holiday setup. Be sure to note the length between your tree and the ceiling.
