Lights over Fishkill N.Y.

While traveling home on Rt. 84 west bound from my brothers house in brewster n.y. ,I came over the hill before the  rt. 9 exit.At this point You can see many miles over the hudson Valley, Newburgh and the Hudson River. A large formation of small multi colored rolling lights (like small Christmas lites in a bunch) headed east to my right.I stopped on the side of the highway many cars and large trucks stopped also. My 10 year old step son was so upset he started crying. It did'nt make the papers.I did'nt see a solid body on this object , just rolling lights ,they passed on Our right and dissapeared behind the mountains.
