Starting in 1978, the light was operated only in poor visibility, along with the fog signal.

The fog signal was finally discontinued in 1995.

The station also included a fog signal building with 12-inch, steam-powered fog whistle.

At the same time work began on installing a fog signal: a 5-inch siren attached to a 36-foot-long acoustic horn, which came into service in 1913; it was nicknamed 'Lord Rayleigh's trumpet' after its designer, the eminent physicist and acoustician.

The fog signal equipment all remained in service until 1963, when the trumpet and siren were replaced by a set of eight 'supertyfon' air horns mounted in a metal turret on top of the engine house.

By this stage the engine house was suffering cracking due to erosion; with automation a new fog signal was installed (a stack of electric emitters placed at the foot of the lighthouse) whereupon the old engine house was demolished.

The fog signal was decommissioned in 2012.

At the same time an experimental electric fog signal was introduced, sounding from 35 Tannoy emitters (subsequently Trinity House installed fog signals of this type at a dozen or so other lighthouses).

After a lengthy delay, a fog signal was installed.
