common problem on these as Pedal says, look on top of the wiring connector on rear bulb strips for rust/ corrosion, a fix is to solder a wire onto the earth on the bulb holder and join it to the earth wire after the connector by- passing any bad connection there,either that or clean up the connector itself if it`s not too bad, good luck.

Failed earth connection somewhere between the bulbs in one or both rear clusters and the bodywork.
