The triangle of lights has no reference objects to indicate what or where it is. The stationary light was much more interesting. Various lights, probably streetlights, in the video were used as reference objects, and showed that the light was stationary over some 30 seconds. An approaching airplane's landing lights will appear stationary, although motionlessness over this length of time seems unusual. A vertical tower structure, apparently made of girders, is near the light.
Some horizontal structure is atop the structure.
It was not sufficiently defined for continuous measurements to be made from it. Another bright object appears to the left and slightly below the stationary object. In 2.9 seconds, it moves toward the stationary object, apparently hitting and exploding. The 5-frame sequence to the right illustrates the sequence. The bright object can be seen to move between the girders of the vertical structure.
