I'm just interested in this particular function here

If i'm not wrong when the switch is pulled out and that light is on the rear fogs should light up? I'm guessing that means the driver side taillight shines a lot brighter than usual. When I pull that switch out and that little light comes on nothing happens at the back. No fog light. Does that mean somethings wrong or did australian cars not come with rear fogs, just like they dont have front fogs usually? If this is the case its weird theyd put a switch with that function
