UFO Sighting in New York, New York on February 25th 2016 – 9 to 10 orbs lights fying from the west toward east and stopped on location above

On Febrauary 25th 2016 I went up to my friend's apartment building on the 20th floor. We had had few days prior to the event of a lot of rain. On that night the rain had stopped so I went out up there. As I was gazing at the cloudy night of NYC at 11:39 pm I noticed these lights approaching East 57th Street, midtown Manhattan and started hovering and all over sudden they flew back and forth as you will see on the video. I tried to look for beam of lights that could explain the lights but I could find any. On top of that, since then I've been asking around for a lighting technology that could give out lights like in he video, so far I have found any, I am still working on it. I did not lose sight of the objects but I got tiered of taping in so I stopped taping and went back to the apartment. Thank you, Rodney
