Aerospace ground maneuver light, comprises a reflector, the reflector defining a light exit plane, an LED light source arranged outside of the area defined by the reflector and its light exit plane, and a mounting bar which has a longitudinal extension and at which the LED light source is mounted. In particular, the invention relates to the use of polymerase inhibitors, including but not limited to anti-polymerase antibodies and fragments thereof, to inactivate residual polymerase activity remaining after the amplification of a target nucleic acid molecule. A backup power source provides power when the primary power source is unavailable.
