2 INTRODUCTION TO LIGHT

3 Major light, minor light, lighthouse Lighted offshore platform L ighted beacon tower Lighted beacon Articulated light; Buoyant beacon, resilient beacon Light vessel, Lightship, Normally manned light-vessel Unmanned light-vessel, light float LANBY, superbuoy as navigational aid

4 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.
