Recently I noticed at KSEA at night that the holding lines that separate the taxiways from the runways are invisible at night when you leave the runway. I think that's not correctly modelled. I think the real lights light red on the taxiway side, and they light green at the runway side.
AFAIK those lines have a dual role: Before entering the runway you wait and contact tower for permission to enter ("taxi to active"), and after touchdown you contact tower to tell them that you left the runway ("cleared runway"), being handed off to ground.
X-Plane ATC does not model these things correctly.
So are those lights correct at night?
