Vippefyr

A vippefyr or bascule light or tipping lantern was a type of small navigational aid popular in Denmark in the 18th century and before. It consisted of a basket in which wood or coal was set; this was then burned. The basket was affixed to a lever that allowed it to be manipulated as required. (The bascule – from the French for "seesaw" – refers to the counterbalancing of the lever, which facilitates raising and lowering the basket; when one end is lowered the other is raised.) The vippefyr system was generally viewed as ineffective, as it produced little light and was usually unreliable.
