DURING THE PREFLIGHT INSPECTION, THE EMERGENCY LIGHTS TOWARDS THE REAR OF THE AIRCRAFT, FAILED TO ILLUMINATE.  OUTSTATION MAINTENANCE INSPECTED THE AIRCRAFT FOR A FERRY FLIGHT TO PIT FOR REPAIR.  THE FLIGHT WAS COMPLETED WITH NO PROBLEMS. PIT MAINTENANCE INSPECTED AND REPLACED THE EMERGENCY BATTERY PACK 7LK, IN ACCORDANCE WITH DORNIER MAINTENANCE MANUAL 33-51-01.  OPERATIONAL CHECKS WERE COMPLETED, AND THE AIRCRAFT WAS RETURNED TO SERVICE.
