INTERNATIONAL NUMBERS OF LIGHTS

The numbers assigned to lights in Admiralty List of Lights, prefixed by the Volume letter, are the International Numbers, in accordance with the resolutions of the International Hydrographic Organization.

These letter-figure combinations should be quoted whenever lights are referred to.

DESCRIPTION

Information is tabulated as follows:

Column 1: Contains the number of each light.

Column 2: Location, name.

Place is printed in CAPITALS.

The names of lights having a range of 15 miles and over are printed

in bold type;

those of less than 15 miles range are printed in roman type; those of

light-vessels in ITALIC CAPITALS and those of all other floating

lights in italics.

Column 3: Latitude and longitude are approximate.

Column 4: Characteristics and intensity.

Column 5: Elevation in metres.

Column 6: Range in sea miles, in bold type if of 15 miles or more, and in roman

type if less.

Column 7: Description of structure and its height in metres.

Column 8: Remarks. Phase, sectors, arcs of visibility. Minor lights.

The layout of column headings is shown inside the front cover.

Phase is expressed to tenths of a second where known unless otherwise stated; it is printed in italics.

The durations of light and darkness are those for which the apparatus was designed. In practice they are subject to some degree of fluctuation, due to slight variations in the working-speed of the apparatus. The duration of a flash may also appear to be less than normal when seen from a great distance, and haze has the same apparent effect.

The limits of sectors and of arcs of visibility, and the alignment of direction lights and leading lights are given as seen by an observer from seaward. All bearings refer to the true compass and are measured clockwise from 000 to 359.

Coast radio stations, radar stations and radiobeacons are mentioned in the List of Lights when they are situated at a light-station, but for details reference must be made to Admiralty List of Radio Signals.

Signal stations and weather, ice, storm, danger, tide, tidal stream, traffic and port signals are mentioned when they are shown at light-station; full details will be found in the relevant Admiralty Sailing Directions.
