Ever seen those strobe lights in rooms on newly built or renovated buidlings? Flashing away, maybe in only one or two rooms at time?
What are these lights for? They don’t seem like emergency
lights being tested, but maybe they are.

Are you sure you’re not seeing the blue-white arcs of interior welding?
no this is not welding, no one is even in the rooms.
If they are on top of the structure, they are there to warn aircraft that there is a building there.
