 The lighthouse is painted white and emits two white flashes every five seconds.Due to the fact that the lighthouse is placed on a hill, the light source stands at approximately 38 meters (125 feet) above the water's surface.Since Palmido Lighthouse, the first western style lighthouse in Korea, was build off the coast of Incheon in 1903, Amtaedo Lighthouse is one of the oldest lighthouses in South Korea.
