For anyone with a passion for pavement lights here are some photos of a couple of deck lights.

These were removed from a wooden boat during some restoration work by my brother in law. The boat was originally built in 1947 (served as a 'Scottish Islands ferry') but I believe these lights were installed in the 1970s and are likely to have originally come from another boat. The lights are set into bronze housings (bronze withstands salt water corrosion better than most metals) and one housing is stamped 1083 but there are no other marks that I have noticed.
The glass has a slight lilac tinge which is much more pronounced in the photos than it is to the eye. The lights measure 25cm by 7cm, the triangular bit is about 5.5cm deep. With housings, they weigh over 3kg each.
Enjoy.
