2 Sets of Tree Dazzlers! Just place these LED Christmas Tree Lights Dazzlers on top of your tree. Then arrange the vertical strands of LED christmas lights into the position you desire. The hardest part will be choosing which lights ‘show’ mode you want to display! Only used one season-one set is all working* and there are a few bulbs out in the 2nd set but can hardly be detected; these units stack on top of each other at top for more lights in your tree*a couple maybe 1/2 lit! Keep a solid color or multiple, steady or flashing—-> SO MANY DIFFERENT CHOICES -display a different one every night! Boxes & paper directions NOT included!
