I know that the strobe lights that flash in rapid succession of each other indicate the open end of the runway, to help guide pilots in at night. It's obvious the white lights indicating the edges of the runway. And I'm guessing the green lights at one end, indicate the open end, whereas red lights at the other end indicate you are approaching the end of the pavement.
But what are those lights at the ends of runways on (typically red) poles. Typically in large sets with one set on either end? Are these just to help the pilot line up? I would assume the actual runway edges and center lighting would assist with that?
