From Pathfinder Wiki
These markings are called daymarks. Lighthouses have unique daymarks so that they can be distinguished from one another. If all lighthouses were round brick towers, a sailor would have to have a pretty good idea of where he was to know which lighthouse he was looking at. Instead, lighthouses are painted with easily distinguishable patterns. Often these are red and white, or black and white. Daymarks can be bands, diamonds, squares, rectangles, or any other shapes - so long as they can be seen from afar.
