I noticed in many pictures of the Boeing 737 and after flying on one several times, that the landing lights on the Boeing 737-100-500 have their landing lights on the flap canoe, and on the 737-600-900ER have the landing lights on the bottom of the fuselage. My question is why did Boeing opt to put them lower on the 73NG series as opposed to the flap canoe?
Also this is on a bit of a side note, but what dictates where to put these landing lights? I know on the Airbus A32S there located near the landing gear, and on some of the 707 models, there located between the two engines as well.
