## Discrepancy

LANDING GEAR GREEN DOWNLOCK LIGHTS DID NOT ILLUMINATE AFTER GEAR EXTENSION.  ALSO, UNSAFE LIGHTS WERE OUT.  CREW PERFORMED GO-AROUND PROCEDURES AND VERIFIED VISUALLY THROUGH PERISCOPE THAT GEAR WAS DOWN AND LOCKED.  MAINTENANCE FOUND RIGHT MAIN DOWNLOCK SWITCH CONNECTOR LOOSE.  CLEANED AND RESECURED CONNECTOR, OPERATIONAL CHECK NORMAL ON GROUND.
