* each nav-light port is comprised of 2 lights, one fwd one aft (redundancy)
* the stab logo lights are located at each main wing-tip aft
* 4 wheel-well lights total: 2 flood lights and 2 gear inspection lights
* white aft stab-tip nav lights (if fitted) are fixed and dont flash
* some 737s have a single rudder-strobe fitted
* yes strobes are located on the red/green position lights forward of the respective forward nav-light
* wing-ilumination lights located on the fuselage just forward of the leading-edges
* inboard landing lights located in the same housing as the runway-turnoff (taxi) lights
* outboard landing lights located on the 3rd (furthest outboard) flap-fairing. They extend out of and retract into this fairing.
* 1 nosewheel-bay flood light located on the bays forward wall, and one inspection-light located above the nose-gear assembley
And if your pedantic:
2 emergency exterior flood-lights located on both sides of the fuselage just aft of the main wing trailing edge, abeam the first closest inboard flap fairing (these lights are through the emergency-lighting system).
