## Discrepancy

ON APPROACH, THE NOSE GEAR GREEN DOWNLOCK LIGHT DID NOT ILLUMINATE AFTER GEAR WAS EXTENDED.  RECYCLED GEAR AND NORMAL INDICATIONS WERE ACHIEVED.  AIRCRAFT LANDED WITHOUT INCIDENT.  MAINTENANCE COULD NOT DUPLICATE DISCREPANCY ON GROUND.  REPLACED NOSE GEAR DOWNLOCK SWITCH AS A PRECAUTION, OPERATIONAL CHECK NORMAL ON GEAR SWING.
