If you’re a car-show nut looking for an edge, look into Razorlite (www.razor-lite.com). This stuff is a really cool pliable film that lights up in a variety of colors. You can use it to add highlights, logos, and other illuminated details to an audio system or just about anywhere else. Razorlite uses light-emitting capacitor technology, resulting in a film that’s only 11mm thick. It emits a bright light without a lot of current and using colored overlays, you can customize the colors.
