The product description say's 'Pre-Lit'. My interpretation is that there would be some kind of battery pack with a switch to turn on the lights.  My fault for not investigating further. This product comes with a plug that controls the lights. I would abandon this wreath if you plan to hang it on your front door as was my plan.  There is no way to conceal the dark green cord so that you can plug it in a slick way.  Who wants a cord (a short cord at that)extending away from their front door? It looks nice even when it's unlit, but it is not what I was expecting. It also sheds a lot of glitter.
