This is for the Medium size Light up Gator Dragons We decided to give our gator dragons the ability to have light up the eyes! These dragons have holes in the eyes to add a small led light that uses induction power. These can be powered off of wireless cell phone chargers. Then to finish the eye, you can either add a 3d printed eye file which is included (we have two different ones) or use a 8mm glass cabochon. You may need a small amount of glass to hold the eye in.
