In infinite flight, one can see the lights shining from the plane but not hitting the ground like an actual plane would. This is a small issue in my opinion but with big effects such as making taxing difficult.
This is a known issue. In fact, someone has already created a Features topic on it. Simply vote for it and maybe comment about it as well so it gets more attention.
The more votes there are, the more likely the developers will improve this. It’s probably already on their agenda, I bet.
