The lighthouse sits just off the coast of the village of Titran at the western tip of the large island of Frøya. It is Norway's tallest lighthouse. The lighthouse is lit from July 21 until May 16 each year. It is not lit during the summer due to the midnight sun in Norway. The lighthouse is also equipped with a foghorn.[1] The {{convert|45|m|adj=on}} tall cylindrical, cast iron tower is painted red with a white base and two horizontal white stripes around it. The tower is attached to a two-story lighthouse keeper's house. The main light sits at an elevation of {{convert|46|m}} above sea level. It is a white light that flashes twice every 15 seconds. A 1st order Fresnel lens has been in use since 1923. Part way up the tower, a secondary light is also located about {{convert|31.5|m}} up the side of the tower. The secondary light is a white isophase light that is on for two seconds and off for two seconds. The main light can be seen for {{convert|18.5|nmi|km mi}} in all directions and the secondary light can be seen for up to {{convert|14.6|nmi|km mi}}, but can only be seen from one side of the tower.[2][3] The lighthouse was built in 1899 and it was automated in 1993. The lighthouse lost power in 2008, and the power supply was out for some time.[4] Media gallerySee also{{stack|{{Portal|Norway|Lighthouses}}}}
