28th Civil Engineer Airmen light up flightline
Staff Sgt. James Livingston, 28th Civil Engineer Squadron electrical systems craftsman, unscrews a light cover before removing the light ballasts here, July 22. Sergeant Livingston checks the light bulbs as well as the ballast, which acts as an individual transformer for each light fixture. The light fixtures serve as extra security at night on the flightline. (U.S. Air Force photo/Airman 1st Class Anthony Sanchelli)
