Abstract
This invention relates to a lighting system for a rotating object wherein the lights are made to appear stationary by being turned on and off in synchrony with the rotation of the object. This synchronization is achieved by utilizing magnetic field sensors which determine the instantaneous orientation of the object relative to the Earth's magnetic field.
