I would still be inclined to a bad earth which fails when asked to provide a higher current draw if possible undo the earthing mounts clean and retighten them. There is a major earth mount on the strut tower on LHS of engine bay in the early series focus.
Easiest check is to supply independent earth wire to the tail lights and see if your problem still occurs
