By 1867 a 7 cwt bell had been installed at the lighthouse to serve as a fog signal. In 1879 a larger (32 cwt) bell was installed, and the old bell was transferred to Gunfleet Lighthouse. (The new bell had previously been in use at Start Point lighthouse, where a fog siren had replaced it two years earlier). The bell sounded four strokes every minute in foggy weather. The following year, the light was made occulting (being eclipsed for three seconds every half minute).
