## Discrepancy

ON APPROACH, THE GEAR HANDLE WAS SELECTED DOWN. THE 3 GEAR DOWN GREEN LIGHTS ILLUMINATED AND THE 3 RED UNSAFE LIGHTS ALSO ILLUMINATED ON BOTH THE FORWARD AND OVERHEAD PANELS.  ACFT CARRIED OUT A GO-AROUND AND ON SECOND APPROACH WHEN THE GEAR WAS SELECTED DOWN INDICATION WAS NORMAL.  IN REF TO FLEET TEAM DIGEST 737- 32-06009 THE LANDING GEAR HANDLE WAS CLEANED IAW ITEM 5 OF THE OPERATOR ACTION.  THE HANDLE WAS THEN FUNCTION CHECKED 10 TIMES AND INDICATION WAS NORMAL.
