I have a stupid question about the 737 equipped with classic xenon lights buth also equipped with strobes (only my biggest -800 freighter is equipped with LED strobe lights).
For the retractable landing lights that come out of the belly driven by a small motor there are two cockpit switch positions, on in the middle and the other full down…
But even with one landing light retract switch in the middle and the other fully down both retractable landing lights are functional:
What does the middle setting of the landing light retract switch do in a real 737?
