Replaced by the Port Washington Breakwater Light and converted to a normal dwelling, it was restored with the assistance of the Grand Duchy of Luxembourg and currently serves as a museum.

[4] This light was completed in 1849 and consisted of a tower and separate keeper's house, both constructed of Cream City brick.

[5] This lens, at 113 feet (34 m) above the water, gave the light a range of 16 nautical miles; 29 kilometres (18 mi).

His wife took over briefly, then his son Charles Lewis Jr. maintained Port Washington's lights for many years.

[4][5] Keeper Charles Lewis, Jr. retired in 1924 upon the electrification of the pierhead light, but apparently continued to live in the old house.

Upon touring the old light, he offered, on behalf of the Grand Duchy, to provide a replacement tower and lantern in order to restore the light to its original appearance, as a memorial to United States servicemen who fought in the tiny country in World War II.
