I put up our tree about 4 or 5 days ago and tree came with whit liches and I added some multi colored string to brighten it up and then put other decorations on later. After that one day some color lights in the middle started blinking, and we noticed this. A few more days went by and the blinking lights stopped and I forgot about it. Well tonight the colored lights on the top portion of the tree started blinking. My DH and myself were eating dinner and DH said to me, Dear, Look at the tree!!!
