Mobile Bay is a shallow inlet of the Gulf of Mexico, lying within the state of Alabama in the United States. Its mouth is formed by the Fort Morgan Peninsula on the eastern side and Dauphin Island, a barrier island on the western side. The Mobile River and Tensaw River empty into the northern end of the bay, making it an estuary. Several smaller rivers also empty into the bay: Dog River, Deer River, and Fowl River on the western side of the bay, and Fish River on the eastern side. Mobile Bay is the fourth largest estuary in the United States with a discharge of 62,000 cubic feet (1,800 m3) of water per second. Annually, and often several times during the summer months, the fish and crustaceans will swarm the shallow coastline and shore of the bay. This event, appropriately named a jubilee, draws a large crowd because of the abundance of fresh, easily caught seafood.

The Mobile Point Range Lights were a series of lighthouses at the entrance to Mobile Bay, at Mobile Point on the tip of the Fort Morgan peninsula, near Mobile, Alabama, United States. The first lighthouse was built as a landfall light by June 1822 at a cost of $9,995. The lighthouse was a conical brick masonry tower, 40 feet (12 m) tall. It was first lit on 29 September 1822. Fort Morgan was built adjacent to the lighthouse in 1833. The lighthouse was joined by the 200-foot (61 m) Sand Island Light across the mouth of the bay, about 3 miles (4.8 km) away in 1858. This resulted in the Mobile Point Lighthouse being downgraded to a harbor light, at the same time a fourth order Fresnel lens was installed. A period photograph, taken prior to the American Civil War, shows two shorter masonry towers standing on the beach below the main tower, they served as range lights. The lighthouse was subsequently destroyed by cannonball fire in the Battle of Mobile Bay during the Civil War.

North Reef Light is an active lighthouse located on North Reef, a 5.6 square kilometres (2.2 sq mi) planar reef, about 120 kilometres (75 mi) northeast of Gladstone, Queensland, Australia in the Capricorn and Bunker Group. The lighthouse was constructed on a migratory patch of sand inside a fringing coral reef, which over the years disappeared and reappeared, as sand was washed away and accumulated, and is now a vegetated sandy island. Its construction is unique, having a hollow concrete base that both gives it resistance to the shifting nature of the sandbar and serves as a freshwater tank. As such, it is considered one of the major achievement in Australian lighthouse construction. It is also notable in that due to the harsh conditions, only bachelors were allowed to serve as lighthouse keepers. At 24 metres (79 ft) it is also the tallest of Queensland's timber-framed iron clad lighthouses.
