To go back to the beginning of the thread then, Jay, why do the airlines
bother?

Help me here -- I can't find any reference in this thread to airlines
using their landing lights en route.

While landing and taking off, yes -- but I thought we were discussing
whether landing lights actually enhanced visibility outside of the
airport environment?
