Ah, I never knew that was how lighthouses worked, so I stand corrected. Edited - actually having thought about it, I don't!
So how does the sailor know the difference between the 'omni-directional' flash and the flash caused by the beam sweeping?
Edited - I don't think they can, because lighthouses don't work that way.
(I still don't see the analogy to paying for LARS)
