Lighthouses
Lighthouse is a means of navigation equipment in the form of a capital structure of a tower type, designed to determine the position of ships at sea This structure often has a bright contrasting color, visually distinguishing it from the surrounding area. Lighthouses are equipped with a strong light source and, as a rule, are equipped with optical means to amplify the light signal so that they can be clearly visible at night. The lighthouse can also send sound signals to ships and / or transmit a radio signal in order to perform its function in poor visibility conditions (temporary, as in fog, or permanent - for example, caused by terrain conditions).
