It was a very simple install with the switch as shown above. I purchased my switch from Tischner BMW.
I'm going to contact them to see if they can start carrying this for the X3. I might be the same switch in the new 3 so it'd be worth while.
Yes, you are correct, BMW doesn't think the US drivers know how to use rear fog lights. I have a tendancy to agree with them by all the SUV drivers I see driving around all the time with their foglights on.
Please keep us informed. This one mod I'd really like to do. Thanks
