EL Wire Light-Up Dog Harness
jenfoxbot 
Introduction
Whether it's to keep Fido (or in my case, Marley) visible on an adventure or as an awesome all-year-round costume, a light up dog harness is an excellent accessory for your favorite pup.
EL wire is a great option for wearable lights. It stays cool, is flexible, and comes in lots of different colors. This design uses the SparkFun EL Sequencer to automatically turn on EL wire when it is sufficiently dark outside, so you don't have to worry about locating Mr. Dog to turn the on system.
