Each measures about 23 high. The round bottom base is 5 3/4 wide.The top signal part is about 6 3/4" x 8 1/2". The pair weighs 25 pounds total. I could not find them marked anywhere so not certain of maker of where these were used. The wiring has been cut so will need to be rewired. There is some normal surface pitting but rather minor and as expected from having been used on an ocean vessel. I find no damage or missing parts - see my 12 detailed photos. A signal lamp (sometimes called an Aldis lamp, after Arthur Cyril Webb Aldis, who invented a widely used design, or a Morse lamp) is a visual signaling device for optical communication, typically using Morse code. Modern signal lamps are focused lamps which can produce a pulse of light. In large versions, this pulse is achieved by opening and closing shutters mounted in front of the lamp, either via a manually operated pressure switch, or, in later versions, automatically. With hand held lamps, a concave mirror is tilted by a trigger to focus the light into pulses. The lamps were usually equipped with some form of optical sight, and were most commonly used on naval vessels and in airport control towers (using color signals for stop or clearance).
