These side lights you describe are turn signals and were mounted on PV-444 B, C and D models. They were standard equipment from late 1952 on all cars and before that on export models, but on home market models they were mounted as well in case the owner did not want the cuckoo.
PV-444 H and K models had similar lights but of different shape, which came in two versions: with and without parking lights.
From the PV-444 L (B16) the turn signals were mounted at the front and at the rear of the car (January 1957 on). This version (for the front fenders) is the only one I see on Ebay right now, though originally they had clear lenses, not amber ones.
