A major light is a light that is intended to be seen at extended distances and will indicate the presence of prominent land masses or provide guidance into harbours or rivers. This tag is used where the supporting structure is not specified, otherwise the seamark:type tag should take the value of the supporting structure (most often "landmark")

Use seamark:type=light_minor for minor navigational lights.

How to map

Sectored light attributes

Note that sectored lights must bear a sector number (# = 1, 2, 3, ...) even if there is only one sector.
For more information on tagging sectored and directional lights, see: sectored and directional lights.

Example for each sector (# is a number):

  • seamark:light:#:category
  • seamark:light:#:character
  • seamark:light:#:colour
  • seamark:light:#:height
  • seamark:light:#:period
  • seamark:light:#:sequence
  • seamark:light:#:range
  • seamark:light:#:sector_start
  • seamark:light:#:sector_end

Light category

Category Beacon as upper, lower, directional

Light character

Rhythm of light

Light colour

Light group

The number of flashes, the combination of flashes or the Morse character(s) within one period of full sequence.

Light period

Time of the time occupied by an entire cycle of intervals of light and eclipse.

Light sequence

The sequence of times occupied by intervals of light and eclipse for all 'light characteristics' except for occulting where the sequence of times is occupied by intervals of eclipse and light.

Light range

The nominal range at which the light can be seen in nautical miles.

Light sector start

The sector limit 1 specifies the first limit of the sector. The order of sector limit 1 and sector limit 2 is clockwise around the light.

Light sector end

The sector limit 2 specifies the second limit of the sector. The order of sector limit 1 and sector limit 2 is clockwise around the light.

Light height

The vertical elevation of the actual lamp or light source (in meters) above the specified vertical datum (typically, mean sea level) – known as the focal height.
