## Discrepancy

DURING APPROACH, THE RIGHT MAIN LANDING GEAR LIGHT DID NOT ILLUMINATE.  CREW RECYCLED THE LANDING GEAR AND THE LIGHT STILL DID NOT ILLUMINATE.  CREW USED PERISCOPE TO VERIFY THE RIGHT MAIN LANDING GEAR WAS DOWN AND LOCKED.  THE AIRCRAFT LANDED WITHOUT INCIDENT.  REPLACED THE RIGHT MAIN LANDING GEAR DOWNLOCK SWITCH, OPERATIONAL CHECK GOOD.
