station wagon driver rear turn signal and brake light not working on 2007 Ford Focus

have checked bulb and fuse with no results when you try to use the signal it flashes and clicks rapidly obviously indicating a problem the front signal works but blinks rapidly backup and running lights work any suggestions

That bulb is not grounded or is defective. Replace the bulb, if no luck, repair ground circuit or replace the bulb socket!
thanks
