The tower has two tiers and initially two open coal fire lights were displayed.[3] These open coal fire lights were difficult to maintain and were soon replaced by a single oil-powered light within a cast-iron lantern.[3]

In 1860, the oil-powered light was upgraded to a dioptric light and the Mumbles Battery, a fort that surrounds the tower, was built by the War Department.[4]

In 1905, an occulting mechanism, where the light was made to flash, was fitted. This was partially automated in 1934.[4]

By 1977, the cast-iron lantern had deteriorated beyond repair and was removed. A different lantern was added in 1987.[4]

In 1995, the main light was replaced and an array of solar panels and emergency monitoring equipment were added.[3]
