You can wire it with a relay. Why did you want to? The reason they don't do it is because people forget to turn on their headlights later on if the driving lights are on. Most people with a QX just set the lights for Auto. That's what I do wth the Mada. Also, people want the parking lights on at all times because it makes you more noticable. I've heard people wanting the driving on with the high beams. Illegal, but I understand that one.
