Historical Information:

The M2 Instrument Light is referenced in official military manuals TM 9-1530 and SNL F-205 and was issued as part of standard artillery sighting kits across multiple U.S. Army artillery units. It played a critical role in ensuring accurate gun-laying at night or in low-visibility conditions. These lights were often mounted directly to the aiming circle tripod and provided critical visibility for forward observers and artillery crews throughout WWII, Korea, and into the early Cold War period.
