## Discrepancy

DURING LINE CHECK, MAINTENANCE FOUND THE OVERWING EMERGENCY EXIT SIGN LIGHTS ON THE LEFT SIDE WERE INOPERATIVE.  THE EMERGENCY PATH LIGHTING AT ROWS 5, 6, AND 7 WERE ALSO NOT FUNCTIONING.  MAINTENANCE REPLACED THE OVERWING EXIT SIGN BATTERY PACK AND OPERATIONALLY CHECKED THE SYSTEM.  ALL CHECKS WERE GOOD AND THE AIRCRAFT RETURNED TO REVENUE SERVICE.
