## Discrepancy

DURING APPROACH, RIGHT MAIN LANDING GEAR GREEN DOWNLOCK LIGHT DID NOT ILLUMINATE AFTER GEAR EXTENSION.  CREW RECYCLED GEAR AND CONFIRMED VISUALLY THROUGH PERISCOPE THAT GEAR WAS DOWN AND LOCKED.  GREEN LIGHT DID FINALLY COME ON.  FLIGHT LANDED WITHOUT INCIDENT.  CREW DID PERFORM GO-AROUND DURING TROUBLESHOOTING OF SYSTEM.  MAINTENANCE REPLACED RIGHT MAIN GEAR DOWNLOCK SWITCH AND CLEANED CONNECTOR.  OPERATIONAL CHECK NORMAL ON GEAR SWING.
