Here is a picture showing that "rotating" nav light you guys were speaking of -
The light itself doesn't actually rotate, there is a mirror that rotates instead. However, this system was very maintenance intensive, and the US disallowed their use as an "anti-collision light" in the 1970's because of repeated in-service failures of the devices. Only a few airplanes still have them, and as this unit was installed on 727-100 N708DH (s/n 18275), it is not in use anymore either as the airplane was retired to Kingman several years ago.
