Beacons/anticollision lights and engines

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.

The nature of the anticollision lights is a certification (the rules
changed over the years progressively) issue. There's no need to
operate a beacon to meet the regs in any of the cases you describe.
If the pilot decides that there is conditions warrant they should
be off, he can turn them off. If conditions are not such that
they need to be off, they should be on while operating the aircraft.

I don't have a beacon. I'm not even required to have any anti-collision
lights, but I have an STC for strobes. I don't use the strobes in
dim or dark conditions on the ground. I'm also careful where I point
my not required by the regs landing light as well at night.
