A lifebuoy light marks the position of a lifebuoy.
 
It is usually attached to the lifebuoys on board the ship. In case of a man overboard, the lifebuoy will be thrown overboard together with the lifebuoy light. It marks the position of the lifebuoy for the person who has gone overboard and for the ship or the rescue boat.
