Rear lights don't work with fogs off but do work with fogs o

[Ferg Sail]

Hey crew, 

My lights don't work when I have my fog lights off but for some reason they work when my fog lights are on. 

Has anyone else had this problem?

Is it just a wiring issue or something bigger?

Always worth inspecting the wiring in the flexible harness section between body and tailgate/boot. Wires are prone to fraction at this point. 
Perhaps you could let us know if that is the culprit or can be eliminated.

Kind regards,

Gareth.
