I installed my euro switch a while back but I never had working fogs. So I could have no lights, parking lights or all lights. Today I got my fog lights working but they only come on with the headlights. When I have just the parking lights on I thought I was supposed to be able to have only the fogs on as well without the headlights. Is there something else I need to do to enable this feature? Or is it just my luck and the switch is bad?
