These small LEDs are connected to a coin cell breakout board with a build-in on and off switch. We 3d printed a small enclosure and clip to attach the whole circuit to apparel! This super easy project is great for Halloween or any character with glowing body parts. Perfect for cosplay events or even for safe night riding!
