According to european Z forums a substantial group of owners are having troubles with their tail lights. Replacement is hard to get and the plans of the Z8 Club are on the back burner ( I think) To avoid problems in the future I ordered last week a complete (left/right) set. Today I got the message that the right light is available at the end of the year and the left light is getting there "some day". The prices have increased ( about 20%) and according to BMW NL, BMW AG is waiting for enough orders to do a new production run. So if you want a spare set just order them now :-)
