## Discrepancy

DURING CLIMB-OUT, THE LEFT MAIN LANDING GEAR UNLOCK INDICATION LIGHT REMAINED ILLUMINATED WITH ALL OTHER INDICATIONS NORMAL.  THE FLIGHT CREW RECYCLED THE LANDING GEAR HANDLE AND FOUND NORMAL OPERATION AND INDICATION OF THE LANDING GEAR SYSTEM.  AIRCRAFT LANDED AT DESTINATION WITHOUT INCIDENT.  MAINTENANCE REPLACED THE LANDING GEAR PROXIMITY CONTROL UNIT.  OPERATIONAL CHECK OK.
