I don't know if or ever PD will revisit any of the existing tracks adding 24 hour & weather, but there is at least a couple tracks in this game that should be full 24 lighting from the start, Trial Mountain & Alsace Village have pit lighting & some track lighting there maybe other tracks, for some reason PD hasn't implemented.
Running a race last night at Blue Moon Infield on a custom race at night, with all the light posts, and light fixtures around the track, but running in pitch black just seems unfinished. With a night setting might come away with a different feel of some tracks, Dragon Trail lit at night through the chicane and pit, bleachers lit up.
