EL wire, or electroluminescent wire, is a flexible wire coated in phosphor. Apply the appropriate voltage and it lights up! It looks a lot like a thin flexible neon tube. They come in many bright colors (check below for other colors) and can be driven pretty easily with an inverter. Check below for compatible inverters as well.
This particular wire glows blue and is 3m (almost 10 feet) in length, 2.3mm in diameter and is terminated with a JST PH connector. This connector works directly with our two driver boards, the El Escudo and the EL Sequencer. Or, you can wire them directly into the output of an inverter.
(The video states they are 6 foot in length, but they are actually 10 feet in length)
