## Discrepancy

EMERGENCY LIGHTING: ENROUTE EMERGENCY LIGHTS ILLUMINATED IN THE ARMED POSITION AND REMAINED ON STEADY THROUGH DURATION OF FLIGHT.  ONLY WAY TO EXTINGUISH THEM IS IN THE OFF POSITION.  TROUBLESHOT PER FIM 33-30-00-810-801-A/200 AND FOUND THE NUMBER ONE EMERGENCY BATT WAS BAD. REMOVED AND REPLACED NUMBER 1 EMERGENCY BATT REF  AMM 33-52-01. OPS CHECK GOOD AT THIS TIME.
