Our TechnoStrobe Funlight is 4 feet of High Bright 2.6mm Cool Neon wire soldered to our TechnoStrobe driver. It has a side switch with on, off, or strobe modes as well as a handy belt clip. Our TechnoStrobe Funlights now come with an extra clip so that you can attach your Cool Neon wire to just about anything! The strobe option is super cool, allowing your Cool Neon wire to appear to be in motion even when held still. Two AA batteries are included.
