I love doing outdoorsy things with my dog and often it's dark before we return. I decided to make an LED dog vest since it allows her to wander further away while still being visible. Plus, it's extremely utilitarian -- especially when camping. I can simply snap my fingers or give her a whistle and she'll run over to flood the area with light.

One important consideration to this design is that the LEDs point downward so that they don't blind you or your furry friend. Since all dogs vary in size and shape, keep this in mind when cutting your LED strips (more on this later!)
