[4] The lighthouse is visible on the horizon from the windows of high-rise buildings in downtown Wilmington, Delaware.

[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.

The Marcus Hook Range Front Light stood about 100 yards (91 m) offshore, 1.6 miles (2.6 km) to the northeast of Marcus Hook Range Rear Light.
