I don't run strobes in IMC at night because the flashing

near other airplanes on the ground at night because it
blinds the other pilot. I do run normal positions lights
and rotating beacons. At night I also run recognition
lights if I have them. Some of the planes I flew had logo
lights on the tail and I would run them too.

I think most pilots have problems with strobes in IMC at night. I don't
run them then or on the ground but I know a few who do. An beacon is
sufficient to meet the regs in both those cases, although I'm sure there
are some pilots who think strobes are required at all times. There's no
other explanation for those few blinding the rest of us on the ground.
