I saw 3 unusual lights in the sky over the gulf of mexico

12/29/21 @ 8:06PM - While at work in my condo building, I was on the roof of the building checking elevator equipment room temperatures. I was 23 stories high and as I looked at the gulf in the northern direction at about 3o degrees west I noticed 3 lights in the sky over the water. The lights were white and bright at night over the gulf of Mexico. They looked to be in a shape of a circle but when I zoom in on the video they could be oval shaped.
The lights formed a triangle and seemed to be still at about maybe 1000-2000 feet. After a short time the the light at the top of the triangle moved east. I took a video with my iPhone 13 for 1 minute and 36 seconds. I thought what I observed was unusual and forgot about it until I watched a documentary on Shotime on UFO’s.
