fog bell
Harbor mist signal
A fog bell is a bell rung as a warning signal in foggy conditions, typically at harbors, lighthouses, or on ships to alert vessels to hazards or indicate position when visibility is poor.
Before electronic navigation, fog bells were essential safety equipment along coastlines: The fog bell clanged steadily through the night.
