DURING MAINTENANCE BASE INSPECTION FOUND THE AISLE OVERWING EMERGENCY EXIT FORWARD SIGN DOES NOT ILLUMINATE.  THE AIRCRAFT WAS REMOVED FROM SERVICE.  REMOVED AND REPLACED THE SIGN IAW AMM 33-50-15.  REMOVED AND REPLACED THE NR 6 INVERTER IAW AMM 33-50-11.  THE OPERATIONAL CHECK WAS GOOD.  THE AIRCRAFT WAS RETURNED TO SERVICE.
