This section displays graphically some of the more common lights and shapes required by the 72 COLREGS. It is by no means a complete display and should not be regarded as such. The 72 COLREGS themselves remain the authoritative source for the positioning and technical details of the required lights and shapes. These illustrations are designed to aid the reader in recognizing and identifying the more commonly encountered situations on the high seas.
The lights in the following illustrations are represented by portions of a “disc". A top view of the arc of visibility for the various lights represented is shown here.
