sparkfun COM-12930 Electroluminescent Wire, 3 m L, Blue/Green Sheath, 80 to 110 V

EL wire, or electroluminescent wire, is a flexible wire coated in phosphor. Apply the appropriate voltage and it lights up. Each EL wire looks a lot like a thin flexible neon tube and they come in many bright colors which can be driven pretty easily with an inverter. As this is a chasing EL wire you will see the glowing blue-green light seem to move across the length of itself as if it were flowing out the end, this feature provides you to add some really fantastic lighting effects to your next project. This particular wire is 3 m (almost 10 ft) in length, 2.3 mm in Dia and is terminated with a four-pin JST SMP connector. Each EL wire is also designed to be driven at 3.3 V with an inverter. The connector works perfectly with the inverter and pigtail that have come out with this EL wire line, which can both be found in the recommended products section below.
