The 77W doesn’t have this, so what is it?
If you don’t see it just zoom it.
I’m not sure, but I appears to be door lights. They aren’t illuminated while flying IRL. Only While on the ground.
The closest one to the front of the wing is called the wing light and it is brighter than the rest, it illuminates the wings’ leading edges to look for ice
It seems to be linked with the door like the other ones are.
I guess the closest lights to the door and cargo doors help you figure out where the door is, the one that’s just isolated are wing lights.
Probably for the doors like there saying
