  3. DESCRIBING A LIGHT'S CHARACTERISTICS THREE FACTORS ARE USED TO DESCRIBE A LIGHT'S CHARACTERISTICS: 1) LIGHT RHYTHM • LIGHTED AIDS TO NAVIGATION ARE EITHER "FIXED" (CONTINUOUSLY ON) OR GENERALLY EXHIBIT RHYTHMS SUCH AS: "FLASHING", "OCCULTING", "ISOPHASE", ETC. (SEE NEXT CHART) 2) LIGHT PERIOD • FOR OTHER THAN "FIXED" LIGHTS, THE TIME IN SECONDS DURING WHICH THE PATTERN OF FLASHES IS REGULARLY REPEATED 3) LIGHT (LENS) COLOR • RED AND GREEN (HAVE LATERAL SIGNIFICANCE) • WHITE AND YELLOW (HAVE NO LATERAL SIGNIFICANCE) FOR EXAMPLE: A LIGHT WITH PUBLISHED CHARACTERISTICS OF "Fl G 6s" WOULD HAVE A FLASHING LIGHT RHYTHM, GREEN LENS COLOR, ONE FLASH PER PERIOD, AND A PERIOD OF SIX SECONDS.
