That strobe effect could be more than annoying. Some pilots are unaware
of flicker vertigo, sometimes triggered by landing into a setting sun.
The idle RPM of a prop shuttering a bright light source can scramble the
brain so thoroughly that the pilot becomes incapable of flying, with
fatal results. As a minimum it's good to find out whether you're
susceptible to this, and if so, avoid landing on 27 at sunset!

I've also read that this flicker can cause a seizure in diabetics...


Yes, and there is also anecdotal evidence in the literature that it renders
viagra ineffective and has triggered coprolalia. That's the reason why I
paint the backside of woods props flat black, or with satin varnish.
