Purpose: Activating the turn signals causes the fog light on the side toward which you’re turning the steering wheel to turn on when traveling at speeds below 50 km/h. This feature is also known as “cornering lights.” Once this feature is activated on your Golf MKV or Golf MKVI, the fog light on the side of the turn will turn on! It’s super handy on narrow roads or in roundabouts.
