## Discrepancy

IAH- WHILE PERFORMING A SERVICE CHECK MAINTENANCE NOTED THAT THE MIDDLE SECTION OF EMERGENCY LIGHTING FAILED TO ILLUMINATE.  MAINTENANCE REMOVED AND REPLACED THE NR 2 (TWO) EMERGENCY BATTERY POWER SUPPLY, PERFORMED A OPERATIONAL CHECK OF THE EMERGENCY LIGHTING SYSTEM.  NO DEFECTS NOTED AND THE AIRCRAFT WAS APPROVED FOR RETURN TO SERVICE.
