Sector lights

Sector lights

Sector lights are a man-made pilotage and position fixing aid that indicates a safe channel through shallow or dangerous waters.

Generally, there are three lights of different colours, each identifying a navigational sector:
* white - this sector is inside the safe channel
* red - indicates the port (nautical) side of the channel for incoming vessels
* green - indicates the starboard side of the channel for incoming vessels

in the United States the phrase "Red Right Returning" indicates the side of the harbor the red light would be on, which would be the STARBOARD side of the craft. The GREEN light would appear on the left or the PORT side of a craft returning to harbor. The convention cited above is for european ports, not US ports. BE AWARE.
