Mains electricity
The light was electrified in 1975, when diesel generators were installed. Mains electricity was brought to the lighthouse in 1989, and it was automated in November 1994. In 2020 Trinity House submitted a planning application for the removal of the Fresnel lenses (and the more modern emergency light currently bracketed to the gallery railings), and their replacement with a pair of static LED lights (one 'primary', one 'standby') to stand on the old lens pedestal. This is part of their programme to replace all the mercury floated rotating lens systems in their lighthouses with static LEDs.
