This is the rear leading light of the Corlis Point range. For the front leading light, please see here. For the CIL page, see here.
My research was obviously a bit faulty. The sat nav reference was obviously a bit out because a half a mile from Querrin pier, it told me I was at my destination. Basically you need to drive through Querrin to the pier. At the coast turn left and its right there. I was out there and had no WIFI, so I didn't know that at the time. Besides, you'd be too close to get a good photo, I reckon. These photos were taken from the beach near the front leading light (see here, which also gives the history and reason for the lights. The rear light has the same characteristics as the front light, except there are six lights instead of four. The night light looks to be the same as the front light (visible in the top photo to the right of the six lights) And obviously, the rear light was first exhibited the same day as the front light!
The tower is a lattice structure 25 meters high and 27 meters above the high water mark.
