## Discrepancy

BDL - MAINTENANCE REPORTED THE SEAT MOUNTED EMERGENCY LIGHTS ON LAST TWO SEAT ROWS (24 & 25 LEFT SIDE) AND EXTERIOR EMERGENCY LIGHT FOR AFT SERVICE DOOR (STA 1000R) WERE INOPERATIVE.  MAINTENANCE REMOVED AND REPLACED THE 5 AMP FUSE ON POWER SUPPLY M1137 AT STA 960 OVERHEAD.  OPERATIONAL CHECK GOOD.
