Status	Attribute label	Enumerant label ▾	Concept definition	Code	Ref type	Reference	Supplemental references
STD 2005/06/07	LIGHT_PATTERN	ALTERNATING	Rhythmic showing, in any given <DIRECTION>, two or more colours in a regularly repeated sequence with a regular periodicity, often alternating.	1	IR	[S57A, Attribute, LITCHR:28]	[FACC, Annex B, CHA:1]
STD 2005/06/07	LIGHT_PATTERN	COMPOSITE_GROUP_FLASH	<<<GROUP_FLASHING>>>, where all of the groups occur as multiple groups within a period; composite group-flashing.	2	IR	[FACC, Annex B, CHA:2]
STD 2005/06/07	LIGHT_PATTERN	COMPOSITE_GROUP_OCCULTING	Rhythmic, in which the total duration of light in a period is clearly longer than the total duration of darkness, and the long duration light periods are separated by multiple short duration light periods; composite group-occulting.	3	IR	[FACC, Annex B, CHA:3]
STD 2005/06/07	LIGHT_PATTERN	DIRECTIONAL	Having a very narrow sector designed to signal or mark a <DIRECTION> to be followed.	4	IR	[FACC, Annex B, CHA:36]
STD 2005/06/07	LIGHT_PATTERN	DIRECTIONAL_MOIRE	A sodium <LIGHT> gives a yellow background to a screen on which a vertical black <LINE> will be seen by an observer on the <CENTRE_LINE>; directional moiré. This pattern is produced by a short-range (up to 2 kilometres) type of directional <LIGHT>.	5	IR	[FACC, Annex B, CHA:43]

STD 2005/06/07	LIGHT_PATTERN	FIXED_LONG_FLASHING	<<<FIXED_FLASHING>>>, in which a single flash of not less than two seconds duration is regularly repeated; fixed/long-flashing.	10	IR	[S57A, Attribute, LITCHR:16]
STD 2005/06/07	LIGHT_PATTERN	FLASHING	Rhythmic, in which the total duration of light in a period is clearly shorter than the total duration of darkness and all of the appearances of light are of equal duration; flashing.	12	PR	[S57A, Attribute, LITCHR:2]
STD 2005/06/07	LIGHT_PATTERN	FLASHING_LONG_FLASH	<<<FLASHING>>> excepting the final appearance of the light, which is longer; flashing/long-flash.	13	IR	[S57A, Attribute, LITCHR:14]	[FACC, Annex B, CHA:46]

STD 2005/06/07	LIGHT_PATTERN	GROUP_QUICK_FLASH	Rhythmic, exhibiting very rapid regular alternations of light and darkness, with a repetition rate of not less than 50 flashes per minute but less than 80 flashes per minute, is interrupted by regularly repeated eclipses of constant and short duration; group quick-flash.	17	IR	[FACC, Annex B, CHA:28]
STD 2005/06/07	LIGHT_PATTERN	GROUP_VERY_QUICK	Rhythmic, exhibiting very rapid regular alternations of light and darkness, with a repetition rate of not less than 80 flashes per minute but less than 160 flashes per minute, is interrupted by regularly repeated eclipses of constant and short duration; group very quick-flash.	18	IR	[FACC, Annex B, CHA:29]
