## Discrepancy

DURING INSPECTION THE LEFT FORWARD EXTERNAL EMERGENCY LIGHT WAS FOUND TO BE INOPERATIVE.  UPON FURTHER INSPECTION, MAINTENANCE FOUND SHORTED WIRES TO THE LIGHTING ASSEMBLY.  REPLACED THE LEFT FORWARD EXTERNAL EMERGENCY LIGHT ASSEMBLY AND THE NUMBER 1 EMERGENCY BATTERY PACK.  OPERATIONAL CHECKS WERE GOOD WITH NO FURTHER DEFECTS NOTE.
