Airfield Lighting
A multi-meter is displayed as U.S. Air Force Senior Airman Aaron Demmon, a 52nd Civil Engineer Squadron electrical systems journeyman from Ludington, Mich., checks voltage on a circuit breaker on the airfield at Spangdahlem Air Base, Germany, Jan. 23, 2014. Demmon used the multi-meter to figure out a solution for a broken strobe light. (U.S. Air Force photo by Senior Airman Rusty Frank/Released)
