Peugeot 207 rear lights not working

I have a Peugeot 207, 57 plate. The rear lights and rear side lights have stopped working. All other lights in cluster are working. Brake,fog,indicator and reverse are all fine. Checked bulbs and replaced, also changed any fuse that relates to lights as there doesnt appear to be a specific fuse for either rear cluster or rear lights. Just ran a voltage test on all terminals in rear cluster, all seem fine and getting power to them. Although side light is running at appox 9v. Earth connections have been checked, and also ran a self made earth to see if that helped but no luck. Ive also reset the bsi as id seen a suggestion it maybe that, but still nothing.

Does anyone know what maybe causing this before I spend out on an auto electrician??
Any help greatfully received

 

Update......
Helps if you change the right bulb, and have a mrs' like mine lol.
Job done.
