This is the Electroluminescent Experimenter's Kit Regular Sign from Micro-Structures.
Turn your ideas into working models with this complete accessory kit. The heart of the set is a specially designed electro-luminescent lamp that measures 1-45/64 x 3-3/4". It's easily cut with a sharp knife or scissors into custom shapes, and can be used to make from one to six lamps. The set also comes with a ready-to-run power supply and an assortment of color overlays for special effects. Plus, a detailed instruction book provides tips and ideas for using electro-luminescent lamps.
Buy the Animated Electroluminescent Experimenters Kit (MCS2502) instead.

I can honestly say this is the 1st Micro-Structures product Ive been disappointed with. You can make a nice sign with it, but only one. Sure there are 6 contacts on the EL light, but there is only 1 contact on the power supply to power it. In order to make use of the remainder of the EL light you would have to purchase additional Electroluminescent Power Supplies (MCS2701) at 6.52 each. I would recommend that instead of buying this kit @ 21.53, spend the extra 1.57 up front and buy the Animated Electroluminescent Experimenters Kit (MCS2502) @ 23.10. The power supply that comes with it has 5 connectors to power 5 signs.
