The Sullivan Island Lighthouse, in South Carolina, is the last major lighthouse built by the Federal Government, completed in 1962,  The tower has a unique triangle shape and looks more like an air traffic control tower than a lighthouse.   One point of the triangle faces the ocean and withstands winds up to 125 mph.  The light can be seen for 27 miles on a clear night.  The lighthouse was originally painted red and white and the residents petitioned the Government to re-paint it to black and white.
