Flashing could possibly account for the most variations in lenses - a non flashing light (a fixed display) would be the traditional beehive design. A flashing light would incorporate one or more bullseyes into the lens. The number of flashes might be determined by the number of bullseyes and/or the speed with which the light revolved.

The HL 4th order lens is modeled after one at the USCG's ANT school at Yorktown, VA.



There are 12 bullseyes. If the lens makes one full rotation per minute, there would be 12 flashes per minute or 1 flash every 5 seconds. If it look 2 minutes to make a full revolution, there would be 12 flashes every 2 minutes, or 1 flash every 10 seconds. If there is one, or two, or however many bulseyes, there would be a flash each time the bullseye passed a given point and focused the light to appear as a "flash" to someone observing the light.

This could get real confusing and real deep before it is done!
