Two bright lights one flashing with a descending expanding ring.

At 5:50 I went outside my house and saw two very bright lights. The one to the left was larger in size and brighter than the one to the right. That is when I noticed the one to the right was flashing every four seconds and an expanding ring was moving downward from it after every flash.
 I am retired Coast Guard and have seen many types of flares including parachute flares and have never seen anything like this. In the cell phone video, the first part I am right on my driveway, then I back up to the street and try to zoom in for a better view. This is where you can make out the flashing and expanding ring clearer.
