This kit consists of our Mini 9volt inverter connected to a 5 foot peice of 2.3mm EL Wire in the color of your choice. You may choose to add a second strand of wire for an even more appealing effect. This entire kit including a 9volt battery (not included) weighs only 3 ounces, making it perfect for mobile remote controlled Planes, Cars, Boats and Helicoptors without an onboard battery source. Adding the second strand of RC Neon EL Wire adds approximately .5oz.
