## Discrepancy

PILOT DID NOT HAVE A NOSE GEAR DOWN INDICATON NO "GREEN" LIGHT AFTER EXTENDING THE GEAR FOR LANDING.  ALSO NOTED THAT THERE WAS NOT "RED" LIGHT OR UNSAFE INDICATION.  PILOT ELECTED TO PERFORM AN EMERGENCY EXTENSION TO INSURE NOSE GEAR WAS DOWN.  FLIGHT WAS AT NIGHT AND TOWER WAS CLOSED.  AFTER LANDING GREEN LIGHT ILLUMINATED.  MX CREW TESTED GEAR SYSTEM AN FOUND NO FAULTS.  SUSPECT THAT LIGHT WAS LOOSE IN SOCKET, OR NOT CLICKED IN ALL THE WAY.  PRESS TO TEST DID WORK FINE.
