## Discrepancy

RIGHT MAIN LANDING GEAR GREEN DOWNLOCK LIGHT DID NOT ILLUMINATE AFTER GEAR EXTENSION.  CREW PERFORMED A GO-AROUND AND VISUALLY CONFIRMED THROUGH PERISCOPE THAT GEAR WAS DOWN AND LOCKED.  LIGHT DID ILLUMINATE PRIOR TO UNEVENTFUL LANDING.  MAINTENANCE REPLACED RIGHT MAIN GEAR DOWNLOCK SWITCH AND LANDING GEAR LEVER RELAY R2-28.  OPERATIONAL CHECK NORMAL ON GEAR CYCLE.
