In the '70's Unity made a double spotlight with the typical clear sealed beam on one side and a red flashing light on the other. They were mounted on the "A" post & controlled as any other spotlight. A switch on the bottom of each shell determined whether the red or clear light was on, and the switch could remain in either position so the light would then be controlled by only the shaft-mounted switch at the end of its handle. Production stopped several years later. I have two re-chromed shells - no dents, cracks, whatever, shell switches and associated hardware for each, but no shafts, bulbs, lens or handles. I have a third complete unit, with gear slippage, made for civilian use - one side has an opening for a clear sealed beam, the other side has a "filler" to hide its opening, as shown. Unity stopped providing parts many years ago, but shafts remain available. As we all know, plating ain't cheap, and I'm balancing the absence of parts with the loss of the replating cost. $100 + shipping for everything shown here.
