Light Characteristic

A light characteristic is a graphic and text description of a navigational light sequence or colour displayed on a nautical chart or in a Light List with the chart symbol for a lighthouse, lightvessel, buoy or sea mark with a light on it. The graphic indicates how the real light beacon may be identified when looking at its actual light output type or sequence. Different lights use different colours, frequencies and light patterns, so mariners can find out which light they are seeing.
