Lights of Dover
DOVER AIR FORCE BASE, Del. -- Dennis Major inspects new lights on the taxiway here. Dover is one of two Air Force installations using new diode lights that use less electricity than older models and are brighter. By design, an aircraft can hit a light and the tube will snap off the base, but the lighting unit itself will not be affected. Major works for the base's 436th Civil Engineer Squadron.
