Kick,
91.209 (b) does give the PIC the authority to leave the anti collision lights off if they pose a hazard. And on the ground near other aircraft they do day or night. I have taken checkrides at night in aircraft that only have strobes with the FAA and they have never had a problem with them being off until I took the runway. They are considered such a hazard on the ground that many airliners have them wired to the sqaut switch on the gear , so they will not operate until the aircraft is airborne.
