Brake Light Fuse Which One Is It

[concalmum]

Hiya, first post here so be gentle. I am actually posting for my cousin, they have a xsara think it a Y reg. The brake lights have gone and they have checked the bulbs they are fine so reckon it must be the fuse. Only problem is they don't know which fuse it is as no indication on the cover which one to replace. does anyone have a pic I could show them of which one it is or and help as to how to go about finding out which one. they bought a haynes manual and that no help.

thanks in advance.

Try F12 in the cabin fuse box under the steering column
