## Discrepancy

EMERGENCY LIGHTS - BOTH FLOOR AND SEATS ON IN LEFT SIDE OF ECONOMY PLUS SECTION OF CABIN.  REPLACED POWER SUPPLY M1559.  OPS TEST OKAY.  EVENT RECURRED TWO SEGMENTS LATER.  REPLACED EEL BATTERY PACK M737.  VERIFIED THIS IS THE CORRECT BATTERY PACK BY DISCONNECTING THE BATTERY AND VERIFYING LIGHTS INOP.  AFTER BATTERY REPLACEMENT LIGHTS IN THIS ZONE OPS CHECK GOOD.
