## Discrepancy

WHEN PERFORMING AND OPERATIONAL CHECK OF THE EMERGENCY LIGHTING SYSTEM, A REQUIREMENT OF THE SOUTHEAST AIRLINES DAILY SERVICE INSPECTION, THE MECHANIC REPORTED THE FORWARD CABIN EMERGENCY CEILING LIGHTS AS WEAK AND WOULD NOT EXTINGUISH WITH THE LIGHT SWITCH IN THE OFF POSITION.  THIS PROBLEM WAS ISOLATED TO THE BATTERY POWER PACK IAW MM 33-53-0.  THE BATTERY POWER PACK WAS REPLACED AND TESTED IAW MM REFERENCE 33-53-0 AND THE SYSTEM OPERATION WAS DECLARED NORMAL.
