## Discrepancy

NOSE LANGING GEAR GREEN DOWNLOCK LIGHT DID NOT ILLUMINATE ON GEAR EXTENSION.  RED UNSAFE LIGHT WAS ALSO EXTINGUISHED.  CREW VISUALLY CONFIRMED THROUGH PERISCOPE THAT GEAR WAS DOWN AND LOCKED.  AIRCRAFT LANDED WITHOUT INCIDENT.  MAINTENANCE REPLACED THE NOSE GEAR DOWNLOCK SWITCH.  OPERATIONAL CHECK NORMAL ON GEAR SWING.  AIRCRAFT RETURNED TO SERVICE.
