History

The permanent structure was preceded by a temporary light on a post, erected in 1915.[4] The present tower was built in 1918 and was composed of nine sections of reinforced concrete; there is also an oil house and a keeper's dwelling on the site. The original beacon displayed a fixed white light using a Fourth order Fresnel lens; this was removed in the early 1980s and replaced with a RL-24 beacon, displaying a fixed red indication. The light was automated in the 1950s, but the keeper's house was occupied by Coast Guard personnel until 2004.[6][7]

In March 2005 the lighthouse became available for transfer under the National Historic Lighthouse Preservation Act, but in 2010 a private owner bought the lighthouse and the accompanying home on the property. The tower is an active aid to navigation and not open to the public.

Front Light

The Marcus Hook Range Front Light stands about 100 yards (91 m) offshore, 1.6 miles (2.6 km) to the northeast of Marcus Hook Range Rear Light.[4] The present tower was erected in 1925 and was preceded by a temporary light tower erected in 1915.[4] It has always been automated.

gollark: I think the basic idea is that while rolling a single die results in each result having the same probability, with multiple dice more than one different individual roll combinations can add up to some results. So the distribution is spikier.
gollark: I don't. I just made a convenient thing to graph the probability of rolling each number a while ago.
gollark: How much of it, anyway?
gollark: Not sure that needs a ping...
gollark: I mean, they are newish features, but I'm not sure they're interesting enough to be worth an entirely new purchase vs KSP 1, with its mods.
