## Discrepancy

WHILE ON APPROACH AFTER EXTENDING THE GEAR, THE CREW RECEIVED TWO OUT OF THREE GREEN LIGHTS.  AFTER CONTACTING MAINTENANCE CONTROL IT WAS AGREED IT WAS AN INDICATION PROBLEM, THE LIGHT WAS OUT.  THE AIRCRAFT WAS FLOWN TO WHEELING THEN CAME BACK TO SHOOT THE APPROACH AGAIN.   FLIGHT 4137 LANDED WITHOUT INCIDENT.  MAINTENANCE INSPECTED AND REPLACED THE BULBS IN ACCORDANCE WITH DORNIER MAINTENANCE MANUAL 33-00-00.  THE OPERATIONS CHECK WAS PERFORMED AND THE AIRCRAFT WAS RELEASED FOR SERVICE.
