## Discrepancy

WHEN CREW EXTENDED GEAR FOR LANDING THE RIGHT GEAR INDICATOR DIDN'T COME ON.  THE BULBS WERE CHECKED WITH THE PRESS TO TEST AND FOUND TO BE GOOD.  CREW REQUESTED A MISSED APPROACH TO RUN GEAR LIGHT CHECKLIST PROCEDURES.  BOTH MAIN GEAR WERE VISUALLY VERIFIED TO BE DOWN AND COMPARED TO MAKE SURE BOTH AT THE SAME CONFIGURATION.  THE EMERGENCY GEAR SYSTEM WAS USED TO VERIFY GEAR WAS DOWN WITH POSITIVE PRESSURE.  THE CREW LANDED WITH NO FURTHER INCIDENT.  IT WAS DETERMINED THE DOWNLOCK SWITCH HAD FAILED.
