## Discrepancy

ON APPROACH, AMBER GEAR LIGHT ILLUMINATED AFTER LOWERING THE LANDING GEAR HANDLE.  RECEIVED  GREEN LEFT, NOSE, AND RIGHT LIGHTS, 'GEAR' DID NOT EXTINGUISH.  ALSO, RECEIVED GPWS BELOW 500 FEET, AMBER ALERT.  *S/D*  DOWN SWITCH IN LANDING GEAR LEVER MODULE FAILED.  GEAR WAS EXTENDED AND LOCKED.  REPLACED LANDING GEAR LEVER MODULE.
