Major light
LightsCore
A star-like position mark with a magenta flare identifies a major light.
What it means
A major coastal light is shown by its precise position mark and a magenta light flare. The adjacent characteristic gives rhythm, colour, period, elevation, and range.Rhythm notation such as Fl(2) 10s is decoded in the Light rhythms guide.
Why it matters
Measure from the position mark rather than the flare, and read the complete characteristic instead of inferring range from icon size.
