Identifying Lighthouses

By: Bianca

A lighthouse is a simple tower made of stone, brick, metal, wood, or steel.  It is a tower located at some place important or dangerous on the coast of a country.  It has a very bright light at the top and sends its light with foghorns, and sirens to help guide and warn ships.

Did you know that there are five basic types of light signals? 

• A fixed light which is a steady beam
• A flashing light which has longer periods of darkness than periods of light
• An occulting light which has longer periods of light than of darkness
• A group of occulting lights which give off two or more flashes at regular intervals
• A group of occulting lights which consist of a fixed light with more and more flashes

  Sailors use maps which show them which type of signals lighthouses have and are guided to the right direction..  Lighthouses have helped sailors for many years.
