The site of the lighthouse, which marks the north end of Cardigan Bay, was purchased by Trinity House in 1876 at the sum of £111 and the next year the stone building was complete.

The main white light has a range of 14 nautical miles (26 km; 16 mi) and its red sector light has a shorter range of 10 nautical miles (19 km; 12 mi).

It gives 1 white and red flash every 15 seconds, the intensity being 12,000 candelas (candle power).

The lighthouse keepers' cottages are now privately owned and used as a holiday home.

The lighthouse building is Grade II listed, as are the lighthousekeeper's cottage and the perimeter walls.
