Here is a picture that shows what these lights look like when you use a more powerful bulb. Also this would be the first position on the light switch and would be used during poor light, but not dark enough for dipped headlights, i.e. the second position. Also this is the same light that lights when you select the parking lights with the indicator stalk and lock the car.
What's show above is (I believe) the non Angel Eyes DRL lights. However, when using powerful LEDs instead of the crappy 5W incandescent weak bulbs you get a similar but much whiter effect. Notice that the indicators are not lit.
