Wholesale Enamel Pin - LED Glow in the Dark

This LED (Light Emitting Diode) soft enamel pin glows in the dark! Charge it by exposing the pin to light. Comes with a backing card and a metal butterfly clutch pin back. 1.25" tall and 0.625" at the widest point. Straight off the breadboard and onto your jacket. Show your love of electronics with this unique pin. Also a great gift for a student and engineer. This LED design started as a graphic I created for teaching. An LED is polarized meaning it only lights up when each of its two legs are connected to the correct side of a battery. The design shows two ways to identify which leg should go to the negative side and which should go to the positive. Do you know which is which? ©Lara Grant, 2020. All Rights Reserved.
