## Discrepancy

THE GREEN NLG LIGHT DID NOT ILLUMINATE WHEN GEAR WAS EXTENDED ON FINAL APPROACH TO CLE.  THE NLG RED UNSAFE LIGHT EXTINGUISHED NORMALLY.  A GO AROUND WAS PERFORMED AND THE GEAR WAS RECYCLED.  THE NLG GREEN LIGHT CAME ON AND A NORMAL LANDING WAS MADE.  MAINTENANCE REMOVED AND REPLACED THE NOSE GEAR DOWNLOCK SWITCH AND OPERATION CHECKED GOOD IAW MM 32-60-1.
