A few months ago, I dug up my Razor scooter out of the garage. I took it all apart, cleaned and lubed it, than put it back together. It looked nice and shiny, but I wanted something more. Then I saw the Let it Glow contest and had an idea. I had wanted to try a project with Electroluminescent (EL) Wire for a while at that point and now I had a use. However, I found myself wanting something more, so I put SuperBright LEDs in the front and back of the deck to light up in front of and behind me. The final product turned out better than I had imagined!
