The lighthouse is a low castellated structure painted white with the round lens room connected to the seaward side of the building. The station is fully automated, the power source being electric, and is backed up by standby generators which cut in should the mains power fail.
There was also an automatic fog detector which used to start the fog signal should the visibility drop to less than 2½ miles, which has recently been turned off.
More history is available in the blog at Pirates of the Caribbean... and Point Lynas. A good full history of the lighthouse is in a book called ‘Lighthouses of Liverpool Bay’ by John and Diane Robinson, available from the history press.
