Just confused on how the DRL's work in conjunction with the headlights. Are the DRL's actually the LOW BEAMS, on a limited voltage? I was thinking of eventually changing out the high & low beam bulbs to a bulb with a bluish tint like the zXe Sylvania's. I guess what I am asking is, which bulb are the DRL's, 9005 or 9006?

 

9006 - Low Beam
9005 - High Beam

 

I beleive the low beams run at 75% brightness during the day . I would also be careful adding aftermarket bulbs. some draw more than OEM and will melt the headlight connectors after while.
