Hi, thanks for sending me your order numbers. Are you sure, that you had this issue in FSX also? I have looked into it, and I believe that it occurs because I have used two different methods for implementing runway edge ligts in the FSX version and in the P3D version. I FSX, the edge ligts are custom modeled lights of the "old" type "bgl lights", where the individual lights are placed at the exact same location as the 3D taxiway edge light model. In P3D, the "bgl lights" type dosen't work, so I have instead used the default "build in" runway edge light system, and kept the 3D taxiway edge light models. But these lights are not in the exact same location as the 3D models.They appear to be emitting light, but that's just the night texture. A temporary solution would be to remove the 3D taxiway edge light models, but I will try and see if I can come up with a better solution. Sorry that I am not able to fix it right now, but I will work on solving the issue.
