Make your own studded choker with an LED twist! This kit of parts comes with all the materials you'll need for a punk style LED collar. Ten juicy diffused red LEDs adorn a high-quality black leather collar that fits necks 12-15 inches (30 to 38 centimeters). Attach the included battery holder and potentiometer, used to adjust the brightness of the LEDs. The simple circuit is powered by a single CR2032 battery (we provide an extra for maximum glow time). Follow our project tutorial (soldering required) to build your own punk LED collar and be the star of your next party or parade! Contains:
