new layer of gun-applied concrete. On completion, new AIS and RACON beacons were fitted, along with a fixed main LED light (and identical standby light) with a 12 nautical mile range; a new fog signal was also installed, sounding two blasts every 30 seconds (altered to one blast in 2022). All are solar powered. The distinctive red lantern structure, removed as part of the refurbishment, is now on display at Hurst Castle, together with the old rotating beacon. In addition, a pair of rotating 4th-order dioptric optics, which were in use on the tower prior to automation, are also displayed at the castle.
