A screw-pile lighthouse is a lighthouse which stands on piles that are screwed into sandy or muddy sea or river bottoms. The first screw-pile lighthouse to begin construction was built by the blind Irish engineer Alexander Mitchell. Construction began in 1838 at the mouth of the Thames and was known as the Maplin Sands lighthouse, and first lit in 1841. However, though its construction began later, the Wyre Light in Fleetwood, Lancashire, was the first to be lit.

At the time of its construction, it was the world's tallest caisson lighthouse. In June 2006, Baltimore Light was sold at auction to private owners by the General Services Administration for $260,000; the U.S. Coast Guard maintains rights to operate a light on the structure.

The Hyannis Rear Range Light, also known as the Hyannis Harbor Light, was a lighthouse and, for part of its life, one of a pair of range lights adjacent to Hyannis Harbor. The Range Rear tower was built in 1849 and equipped with a 5th order Fresnel lens in 1856. In 1863 the original birdcage lantern was replaced with a new cast iron one. In 1885, a front range light was added on the Old Colony Railroad Wharf, and the two lights together served to leading vessels to the wharf. The 20 foot Range Rear tower is shorter than most lighthouses, as its purpose was just to guide ships to the wharf. In the early 1800s, the railroad extended from its current terminus at the Hyannis Transportation Center, down what is now Old Colony Road to Harbor Road, where it ended in the 300 foot wharf that was a busy area for shipping coal, lumber, grain and fish.
