Autopilot use during approach

I'm curious, why don't they let you use it with the landing lights?

If your POH supplement for the autopilot has operating limitations, it
isn't legal to use contrary to those limitations. Mine doesn't allow
use of the autopilot with the landing lights on, for example. You won't
find these anywhere in the AIM or FARs, but they are just as binding as

My landing light circuit turns on 3 100W lamps. With them and the other
equipment that was in the plane at the time the autopilot was added, the
load is just under the 80% or whatever it was of the system capacity.
When I added the autopilot I had a choice of upgrading the electrical
system ($$$) or prohibiting some combination of equipment that would
keep the maximum load under the limit for the existing system. The
easiest to meet was a prohibition of operating the landing lights with
the autopilot on.
