How to use with LED module with magnetic switch.

It surrounds the module like a donut, also blocking out light. The sticky pads can be removed later, making them ideal for temporarily fixing parts in place when replacing batteries.

All that's left to do is set the LED so that the center is visible, and then press it down with tweezers or something similar to temporarily secure it in place. It only takes about 10 minutes to set up the lights, so it's especially recommended for snap-fit models. When removing it, peel it off slowly and it will come off cleanly!
