Why and What is Lighthouse Week End? Lighthouse Act became law in August 7, 1789. Before the United States was a nation, individual colonies and municipalities constructed lighthouses on their shores to guide mariners into harbors. But since operation of these lighthouses was not governed by a centralized body, the lights lacked uniformity in their operation, impacting the safety of the mariners they were trying to protect.
When George Washington became president of the new United States, he was well aware of the importance of protecting its shores. One of the first issues he addressed was the management of lighthouses and central control of navigational aids and recommended “An Act for the Establishment and support of Lighthouse, Beacons, Buoys, and Public Piers,” to provide and regulate navigation. When the Lighthouse Act became law in August 7, 1789, significant improvements in the operation of lighthouses were immediately implemented and operational guidelines were established.
