I have to agree with MD on this one...why is everyone so enamored with auto headlights? Are we so freakin lazy that turning a knob is such a chore? I have it (auto headlights) on mine and never use it. I don't want the ballasts (and self-leveling motors) on my HIDs to have an early death as they flicker on/off every time I'm pulling into/out of my garage, going through overpasses, etc...
