You're totally correct WYSIWYG , just though i'd stick up the MM. Even then both me and MrFixer end up with different no's
Maybe they do flash together and maybe the beacons have some dance with them too. We're all trying to answer the OP's original question , how do they get that far out of synch.
I didn't make myself very clear earlier - each strobe is powered from the same aircraft bus but has an individual power supply which takes that 115v ac and converts it. Hence, over time these power supplies will no doubt output to the light at slightly different intervals to their counterparts on the aircraft.
for the really sensitive among you, my first line was a joke
