## Discrepancy

WHEN GEAR WERE LOWERED FOR LANDING, DID NOT HAVE 3 GREEN GEAR LIGHTS.  PILOT TRIED PRESS TO TEST OF BULBS & TURNED DIMMING OFF TO NO AVAIL.  PILOT TERMINATED APPROACH & GOT VISUAL CONFIRMATION FROM TOWER THAT GEAR WAS DOWN.  PILOT EVENTUALLY SAW ALL 3 GEAR LIGHTS WERE GREEN, BUT EXTREMELY DIM.  PILOT LANDED UNEVENTFULLY.  SUBSEQUENT INSPECTION FOUND THAT THE AMBIENT LIGHT SENSOR HAD AN INTERMITTENT FAILURE.
