They are modeled, but I think it has to be dusk or night in FSX to see them.  Check out the following video, this is from an actual 727 pilot, the lead-in lights are visible at about the :40 second mark: http://www.youtube.com/watch?v=vEAUjgErJyI

Thanks for the link.  I see that the person who made the video is running addon scenery for this airport.  I have tried both dusk and night and I am still not seeing the lead-in lights.  I have my scenery density set all the way to the right.  

Can anyone confirm if these lights are shown in default FSX scenery for the JFK area?
