POBC - help !! Lights

[HendrixsWhiteStratReturns]

Hi all

MOT tomorrow and weird lights issue. All working fine earlier but one fog light out so I swapped bulb and now both fog lights out and passenger side tail light won't work ( but worked fine before and works as a brake light). 

have tried swapping bulbs but nothing ... anyone know which fuse it is (fog lights) under the dash mine is a 1990 Xflow 1700 Supersprint standard spec

electrics not my forte so any advice much appreciated as I scrabble about in a freezing garage ..... thank you

Fuse layout sent.

And I'll try and talk you through the diagnosis if that would help.

Fog lights should only work when headlight dipped beams are on.

I don't know whether it applies to a 1990 car, but this is the fuse layout from the 1995 Owners Manual:

Sometimes there are problems with lights due to poor Earth connections.

Thanks to all for reply - all fixed... dodgy earth on one fog and the unit crumbled when touched so luckily I had a wiper knocking around so chucked it on and also a blown fuse ( that looked on first inspection to be okay).

Thanks again and Jonathan you're a gent chap thank you

Wiper might confuse the MOT man
