Senator John H. Chafee (Rhode Island) sponsored a joint resolution that was introduced to Congress on April 28, 1988 designating the day of August 7, 1989 as “National Lighthouse Day.” The summary of the resolution stated, “Designates August 7, 1989, as National Lighthouse Day and calls for lighthouse grounds, where feasible, to be open to the public.” President Ronald Reagan signed the Bill into public law (No. 100-622) on November 5, 1988.
Q. Why are lighthouses painted differently? Do these designs represent something?
A. Lighthouses are painted different colors and designs to make them daymarks. So, if you were a Mariner out at sea during the day, you could look for the lighthouse.
Q. If lighthouses are painted different to distinguish them during the day, how can you tell them apart in the dark?
A. Similarly, each lighthouse also flashes a different sequence of light for the exact same reason. Cape Hatteras flashes a white light every 7.5 seconds. (The light actually rotates, but it gives the appearance of flashing from a distance.) Cape Lookout flashes a white light every 15 seconds.
