2007 Nuevo rear lights

I suspect there's an easy answer out there!  I don't have any details on the habitation fuses. Suspect from other posts that the rear lights are served from the habitation fuse board under the off-side bench seat.
I have fuse details in the Peugeot Boxer handbook, but rear lights not mentioned on any of the three fuse boards. 
Did remove vehicle battery to charge at home after very cold temperatures recently. Rest of lights ok, when taken for a run last weekend. Bulbs seem ok so fuse next thing to be checked, if I knew which or where it's sited. 
Thanks

If your van is fitted with the MES control panel tap the centre of the screen until you see the screen which shows front and back interior light icons and ensure both are black.
