## Discrepancy

ALL 3 GEAR UNSAFE LIGHTS ARE INOP FROM RESPECTIVE TEST SWITCHES.  REPLACED NOSE AND RT WW LAMPS, OPS GOOD.  LT SOCKET WAS FULL OF CORROSION, CLEANED OUT SOCKET AS MUCH AS POSSIBLE AND CLEANED.  WITH CONTACT CLEANED AND REPLACED LAMP, NO HELP.  NEED TO REPLACE SOCKET.  LOWERED GEAR DOORS, CLEAN LAMP SOCKET, RAISED DOORS TWICE AND ALL DOOR WARNING (RED) LITES WORKED GOOD.
