A Christmas Nightmare

Imagine this. You're sitting on a wooden porch in the middle of a dark forest, the trees invisible in the pitch black of midnight. The faint sounds of a party inside the house behind you. The house is decorated beautifully with multi colored Christmas lights in the spirit of the holidays. As you stare at the shining bulbs on the line of the roof in front of you, they seem to grow brighter. Suddenly, one by one, the Christmas lights blow out, until it's pitch black around you. Then, out of the darkness, you can see two bright red Christmas lights come back on, yet lower to the ground. You suspect a line broke and was close to the ground, but what happens.......when those two lights begin to move?
