Most people think that a lighthouse is only a light and a tower. In fact, depending on its location and the particular needs of ships and the routes they take, some lighthouses manage multiple beacons, which means that lighthouse keepers must ensure that several beacons are lit at the right times.
一般人以為燈塔只是一座上面有燈的塔，其實，因著地形或船舶航行的特殊需要，部分燈塔需兼管好幾座燈，即燈塔看守人需要負責讓好幾座燈塔按時發光，如蘇澳燈塔即轄有四座燈塔。
