There are multiple bright lights in the scene of the same relative color and brightness, as illustrated in the wider-angle shots.
The light visible through the fork in the tree (circled above) is in the distance relative to the other similar lights in the scene. Here's why that seems to be the case ...
The two frames you posted illustrate how it fades in brightness (and diminishes in the glare it causes in the camera optics) at the time of the power cut. If you step through the video frame-by-frame this fade-out is perceptible in the tree-fork-light before the other (closer) lights also start to fade.
If you continue to step through the sequence frame-by-frame you can see the tree-fork-light finally fade to its last visible point a couple of frames before the other / nearer lights wink out altogether.
As the tree-fork-light fades down to a final point source it becomes evident this light is located beyond the tree, ruling out the interpretation of this particular light as an orb (-ish thing ...) in mid-air between the tree and the camera.
What is the physical / ground location of the tree-fork-light? I can't convince myself it might be as close as the roofline of the building(s) on the other side of the parking lot. It seems to be farther away - somewhere on the other side of those buildings.
