Three strange Lights in the sky. 500+ Playlist (2008-2022)

I saw these three lights years ago.
Since then I found a lot of videos
showing the same phenomenon.

Unfortunately, I haven't found any scientific paper or reliable
information about this object until now.
The link goes to my personal Playlist.
