## Discrepancy

UPON GEAR EXTENSION FOR LANDING, THE LEFT AND RIGHT MAIN LANDING GEAR GREEN LIGHTS DID NOT INDICATE DOWN AND LOCKED.  EXTENDED GEAR USING ALTERNATE METHOD.  DECLARED AN EMERGENCY.  LANDING WAS UNEVENTFUL.  MAINTENANCE REPLACED THE LEFT AND RIGHT GEAR INDICATOR LIGHT MODULES.  GEAR INDICATOR CHECKED OK.
