Nissan Navara STX D40 tail light fuse

Afternoon all
I've just hooked up to a faulty trailer and blown my tail light fuse.

have check the owners manual - no help
Have check the fuse box in the clove comparment -- no blown fuses and no mention of tail light (or any other lights)
Have check fuse box on drivers side in engine comparment - no blown fuses
There is another box on passenger slide in engine camparment but that also doesn't mention fuses.

I am assuming that I am no the first to blow a tail light fuse. Does nayone have any idea wher Nissan may have hidden it
Cheers
