littleBits Electronics Light Wire

This is one individual littleBits bit:

The light wire Bit is almost four 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!

What's littleBits? littleBits is an opensource library of electronic modules that snap together with magnets for prototyping, learning and fun.
