Penmon lighthouse
In 1922 Trwyn Du became the first Trinity House lighthouse to be automated,[7] when it was converted to unwatched acetylene operation.[8]
The lamp was converted to solar power in 1996 and the lighthouse was modernised extensively at that time.
At present the Lighthouse has a 15,000 candela light that flashes once every 5 seconds and can be seen 12 nmi (22 km) away. Additionally, a 178-kilogram (3½ cwt) fog bell sounds once every thirty seconds.[9] There was also a lifeboat station built in 1832, nearby, but this closed in 1915.
The tower has been unmanned since 1922 and is checked from Holyhead Control Centre. In August 2019 Trinity House started trials of a new fog horn, stating, "The bell is activated by an ageing electronic striker mechanism which no longer provides the assurance of reliability which is needed
