CR2032 LED Light

This printed case is designed for LED (6mm rim at bottom) and cr 2032 battery. It will emit light without any on/off switch. I am using it eg. for my post box. One CR 2032 for LED light can work about 1 year (depends on color). First insert LED into slot. It has designed cut to properly match anode/catode. Then insert cr 2032 battery. Plus and minus is marked on case. Boost MeYou can support me with boost to make more things like this.
