Interesting that in the UK DRL's are required to dim with headlights, on full stop. This makes perfect sense in the case of oncoming traffic when you would be using dipped headlamps, but is the dimming necessary on full beam without oncoming traffic? I believe some countries adopt this ruling which makes more sense to me.
Also of interest is the DRL dimming kit that CBS sell (or did). Looking at their wiring diagram the trigger feed is from from headlamp low beam, supporting above thoughts.
