Marker buoys, used in naval warfare (particularly anti-submarine warfare) emit light and/or smoke using pyrotechnic devices to create the flare and smoke. Commonly 3 inches (76 mm) in diameter and about 20 inches (500 mm) long, they are activated by contact with seawater and float on the surface.
Graphical and textual descriptions of navigational light sequences and colours are displayed on nautical charts and in Light Lists with the chart symbol for a lighthouse, lightvessel, buoy or sea mark with a light on it. Different lights use different colours, frequencies and light patterns, so mariners can identify which light they are seeing. [1]

It was completed in 1906, replacing a nearby bell buoy. In 1966, the light was automated, and the original 85 m (279 ft) tower of the lighthouse was demolished and replaced by a helipad. The lighthouse was at one time painted with alternating red and white rings, but as of 2017, the lighthouse is painted plain white.
A bell buoy was first used in 1855. [8] Today's bell barrels usually have several movable mallets attached to the outside of the bell. [7] Thus, these sound buoys were in use before the light buoys, which were produced from 1876. The same purpose as bell buoys is served by the whistle buoys invented in 1876, as well as gong buoys, invented in ...
