This has happened to me a few times, especially when there are GPS markers, the lights mess with it.
Can't seem to find a way to replicate, unfortunately.

Random lights appearing bug
Turns out the searchlight system used at Dwayne Island and Area 69 is completely fucked. I was working on something back in Feburary and apparently broke it badly. It's complicated, but I'll fix it or revert my changes.
