The unusual arrangement of having the lantern at ground level with the look-out and telegraph room above is similar to the Great Orme Lighthouse, also built by the Mersey Docks and Harbour Board.
The telegraph station was established in 1879, and two new cottages were erected to accommodate extra staff.
Point Lynas has now been taken over by Trinity House.

A Chance Brothers occulting optic was fitted in the light room in 1878.
This is 1.4 metres (4 ft 7 in) in diameter and displays a light through 206 degrees.
The fixed part of the optic consists of three sections, the central unit on the focal plane has a 0.25 metres (9.8 in) deep curved lens with bands of six prisms above and below it.
The bottom unit is made up of six bands of reflective prisms, while the inclined top unit contains sixteen.

The lamp is 1000W with an intensity of 112,000 candela and is white, occulting every 10 seconds, with a range of: 20 nautical miles (37 km; 23 mi)
