We do not have listings in our reference materials for Peugot's, but I think we might still be able to help you out here. Although I am unable to provide a wiring diagram for you, I would double check the ground wire going to that side of the taillights. With modern vehicle's there are many electrical circuits, so many so that a lot of them share a common ground. If this ground fails then all of the electrical circuits using it will also fail. It is common for manufacturers to put all of the lights on one side and hook them all to a common ground. I have included how to inspect a ground in the diagrams down below for you. Please get back to us with what you are able to find out.
