This begs the question I've had for a long time: Why do interstellar/interdimensional crafts need running lights which traditionally serve the purpose of illuminating a travel path, not space; or alerting other crafts to avoid collisions, which would be useless considering the speeds UFOs travel.
It seems like the only purpose of exterior lights is to make their presence known to earthlings...which seems like something that would be done only by the Deep State cabal for purposes of confusion and/or fear mongering. If genuine aliens wanted to declare their presence, why do so many UFOs take evasive actions once seen. If they wanted to confuse us or terrorize us, they'd have a number of better strategies (e.g. land on the White House lawn, attack us with exotic weapons).
So my general bias is that if they have running lights, they're earth-based pseudo-alien crafts.
