## Discrepancy

DURING APPROACH, THE LEFT MAIN LANDING GEAR GREEN LIGHT DID NOT ILLUMINATE AFTER GEAR EXTENSION.  CREW EXECUTED GO-AROUND PROCEDURES AND RECYCLED GEAR.  NORMAL INDICATIONS WERE ACHIEVED ON SECOND ATTEMPT. AIRCRAFT LANDED WITHOUT INCIDENT. MAINTENANCE COULD NOT DUPLICATE DISCREPANCY ON GROUND.  REPLACED LEFT MAIN GEAR DOWNLOCK SWITCH AS A PRECAUTION.
