Sector light
LightsCore
Radial limits show directions in which a light displays different colours.
What it means
Sector-limit lines and colour letters show which light colour is visible from each direction. The bearings and any obscured sectors are part of the charted information.Rhythm notation such as Fl(2) 10s is decoded in the Light rhythms guide.
Why it matters
White often marks a preferred sector, but it is not a universal promise of safe water. Follow the charted bearings, notes, and pilotage directions.
