Green Ceramic Light Up Christmas Tree, 16"

I've loved my tree for the last three holiday seasons. I take it out of the box, on display and it goes back in the box and stays right in the dining room. It goes no where and yet today when I went to put it away I realized the light wasn't working. I took the light out and realized that inside there were actually 2 light bulbs and neither was working which was odd that they both went out. So, then I wasn't sure if it was the bulbs or the mechanism. I started to unscrew the bulb and the whole mechanism just shredded in my hand. And yes it was a plastic of some sort. There is nothing on the box or in the directions about replacement parts. I'm willing to purchase another part to hold the bulbs but no info is given as to how to order a part or a whole replacement for the inside light. I'm sad because I love it so much.
