Airman 1st Class Cody Owens, 28th Aircraft Maintenance Squadron instrument flight controls system technician, replaces a lamp driver in the cockpit of a B-1 during scheduled maintenance on Ellsworth Air Force Base, S.D., Jan. 9, 2012. The lamp driver controls all of the cockpit lighting, which is critical for aircrews to clearly see gauges, indicators and other equipment.
