When you bike at night, you need lights and reflectors to stay safe from vehicles and other people who might otherwise not see you. MAKE Projects shows you a really cool way to do that and also make your bike look like something out of TRON at the same time.
Electroluminescent wire consists of a copper wire coated in phosphor (a luminescent substance similar to what's in glow-in-the-dark toys), which glows when an alternating current is applied across it by outer wrap wires (aka "angel-hair" wires).
To add EL wire to your bike, you just need enough to wrap around the parts you want to glow and power it with a battery. To give it a shot, check out the full how-to over at MAKE Projects.
