Airmen keep flightline illuminated
U.S. Air Force Airman 1st Class Ernest Kuma, 20th Civil Engineer Squadron electrical systems apprentice, adjusts a ramp light at Shaw Air Force Base, S.C., Oct. 16, 2014. Kuma, along with Senior Airman Anthony Pierce, 20th CES electrical systems journeyman, worked together to change the ramp light bulbs as well as light ballasts, a device that limits the amount of current in an electrical circuit.
