I recently achieved this very look with my euro lights. I ran pin 4 (dim setting) from the side marker wiring assembly to pin 58 in the 6-pin wiring assembly for the euro headlamp assembly. This now powers my city lights in light switch position 1.
If you don't have euro lights, you could simply disconnect pin 4 in the side marker wiring assembly. However, this would result in NO lighting up front unless the headlights are on.
