"AOA indexer lights (Grimes Division, Spec. NA 5-78183, P/N 20020) mounted on left and right hand sides of the windshield (front cockpit). These present landing approach AOA information by illuminating symbolic cut-outs with landing gear down. Lower symbol lit at fast airspeeds, upper at slow airspeeds. The "shoot" light was installed in F-4N, F-4S (and F-4J after AFC506) aircraft. It illuminated when radar lock, range and aspect requirements to a target were met and all switches properly set for launch of the selected air-to-air missile (thanks Bob for the information)."
