littleBits Light Wire

The light wire Bit is almost 4 feet long and its entire length glows a soft blue. It's made of special stuff called "electroluminescent wire," which is great to form into glowing shapes. It's best to use in the dark. We like to use it for wearable accessories when we go to parties!

The light wire Bit uses phosphor as a material to emit light. When the signal is increased, the light wire begins to light up.
