## Discrepancy

DURING APPROACH INTO EWR, THE NOSE LANDING GEAR GREEN LIGHT DID NOT ILLUMINATE AFTER GEAR EXTENSION.  NOSE GEAR UNSAFE LIGHT WAS ILLUMINATED.  FLIGHT CREW RECYCLED GEAR AND DECLARED AN EMERGENCY.  AIRCRAFT LANDED WITHOUT INCIDENT.  MAINTENANCE REPLACED THE NOSE GEAR PROXIMITY SENSOR.  OPERATIONAL CHECK NORMAL.  AIRCRAFT RETURNED TO SERVICE.
