The Dubois rotating beacon is stamped “Dept of Commerce Airways Division 20-80-C-577 Westinghouse Electric, Cleveland” and features a parabolic mirror, a clear glass Fresnel lens on one side and a green removable lens screen on the other. These beacons produced up to two million candle-power and could be seen up to 40 miles away. By 1933, approximately 1500 of them were built, covering 18,000 miles of air routes across the country. The Dubois beacon, though now operational again, is only lit on special occasions and by appointment.
