## Discrepancy

WHEN GEAR WAS EXTENDED FOR LANDING ON APPROACH, THE NOSE GEAR LIGHT DID NOT ILLUMINATE.  THE MECHANICAL INDICATION SHOWED GEAR WAS DOWN.  AN EMERGENCY GEAR EXTENSION WAS USED AND THE AIRCRAFT LANDED WITHOUT INCIDENT.  MAINTENANCE FOUND BOTH GREEN LIGHT LAMPS FOR NOSE GEAR INDICATION BURNED OUT.  THE LIGHTS WERE RELAMPED AND INDICATIONS CHECKED GOOD.
