On my way to a mates house in Carmarthen on friday night, I was passing over the M4 Briton Ferry bridge and happened to glance right over towards Baglan. I spotted a greeny-white light amongst the usual SOX & SON coloured lights, my curiosity got the better of me and I came off at the next junction and searched for the light I had seen.
The light was found on the road in Penrhiwgoch, Baglan.
Seems to be a rather nice mercury installation, Eleco Welwyn I think? I took a photo when I found it on friday night, and popped by there on the way home today to photograph it in the daylight.
Yet another fine vintage installation in South Wales!
P.S. I also drove by the P112 in Swansea, there are no others around apart from that one I could see.
Mike.
