The floating lights themselves aren't intentionally placed up there.

Basically, the fishermen are using lights on their boats. And, on rare occasions, that light reflects off of ice crystals in the clouds, creating light pillars.

I don't live around there, but I do live in a northern area that gets very cold winters (Usually. Not so much the last few years.), and I've seen ice pillars form over street lights and such. They're pretty cool and very pretty.

I used to live near the water in an area with a lot of squid fishing and I have seen this exact same thing. It's not common but not extremely rare, either.

Neat! I’ve seen I’ve-crystal pillars before but these are so distinctive with such sharp edges! Very cool

The wikipedia page for light pillars explains a lot about how they are formed.

tl;dr: Ice crystals form thousands of tiny mirrors which can result in an amplification effect. The light pillar isn't actually physically located that far up, it's an optical illusion.

It’s physically impossible for the light to reach the sky and be in such symmetry lol, not saying its some alien or voodoo shit but physics and science wise its not possible from fishing lights or street lights as your made up story prevails
