This idea has been around for a while.
I just added some additional support for it after trying to get it to work and finally finding the best solution.
Basically it's an item that when double-clicked it equips a light source to your character's unused layer.
There's the base Wearable Light and Base for Armor, Clothing, Shields, and Weapons.
Also included are Example Items to show how to incorporate this into items that the Player can use.
Pretty basic, not too exciting. Just thought I'd share it on here.
