## Discrepancy

DURING APPROACH,  FLIGHT NOSE GEAR SAFE LIGHT WOULD NOT ILLUMINATE AND TOO LOW GEAR AURAL WARNING SOUNDED.  FOLLOWED EMERGENCY CHECKLIST AND DIVERTED.  LANDING WAS UNEVENTFUL.  MAINTENANCE REMOVED AND REPLACED THE NLG DRAG BRACE DOWN LOCK SWITCH. A SUCCESSFUL OPERATIONAL CHECK FLIGHT WAS PERFORMED. AIRCRAFT WAS RETURNED TO SERVICE.
