I have back fog lights on my 2009 X5. I didn't know this until I got a car wash and was driving home pushing random buttons and the car behind me high beamed me. I was looking at her face and kept pushing it watching her face get brighter red then light.

The top left button is for the front fog's and the top left button is fro rear fogs. The pics of the rear fogs were taken in a hurry with my iPhone, and a car came during the last picture. If you want better pics let me know.
