UFO Sighting in Glastonbury, Connecticut on December 25th 2012 - followed each other, switched places then lights faded away

We were driving home from dinner when we saw two bright lights in the sky. We pulled over and got out of the car to record a video. There was no sound at al except for a couple cars going by and the two lights followed each other keeping the same distance between them. Then they switched places and the lights slowly started fading. One light went out completely before the other and then they were gone.
