[Rogue ALS lights]

Well, that led to some interesting reading and commentary on this approach. You learn something new everyday. I grew up on LI and spent a considerable amount of time around and at JFK but had never noticed these. Thanks

[Rogue ALS lights]

I picked up some rogue ALS lighting just West of the airport pulsing from SW to NW directly above the Belt Parkway at 40.657043, -73.856825 (Link: Google Maps.) They can only be seen coming in from the S/SW/W, and they do not correspond to a runway.  I grabbed a snapshot of the area but only managed to catch one of the pulses.
