Strumble Head Lighthouse stands on Ynys Meicel (from Welsh: St. Michael's Island), also known as Strumble Head, a rocky island at the northwest corner of Pencaer area, five miles west of the town of Fishguard, in northern Pembrokeshire, Wales.

The circular stone tower is 55 ft high and still contains the original lantern complete with Fresnel lens manufactured by Chance Brothers, using a mercury bath as a low-friction bearing.

The Lighthouse was fully automated in 1980 and is now monitored from the Trinity House Operations Control Centre at Harwich with regular visits made by an attendant.

A plaque in the lantern-room is inscribed with a verse from Psalm 127: Except the Lord Build the house They labour in vain that build it Except the Lord keep the city The Watchman waketh but in vain Under the lantern room sits a water tank which was used to store rainfall for use in the lighthouse's accommodation.

Stores were transferred from the mainland by cable but now largely arrive by helicopter and a helipad is found to the west of the lighthouse.
