## Discrepancy

EMERG EXIT SIGN/LIGHT: WITH THE AIRCRAFT BATTERY SWITCH ON AND EMER SWITCH ON, ALL EMER LIGHTS WORK NORMAL. WHEN TURNING THE AIRCRAFT BATTERY SWITCH OFF, THE EXTERIOR EMER LIGHTS OVER THE WING AND THE EXIT SIGNS IN THE AFT PART OF THE CABIN DO NOT WORK. CORRECTIVE ACTION: REPLACED BATTERY. OPS CHECK GOOD.
