Daytime Running/Headlight Question

#1
How does this work. Since the Daytime running lights run off the Healights. Is there a double filliment in the headlight or is less voltage applied to get less brightness? Reason i ask is because my headlights arent that bright and they seem pointed down. My highbeams are good, its the headlights. I replaced them thinking the other ones were originals. No difference in brightness. Also how do i adjust there hight? I was looking but couldnt see a spot to raise or lower..

Less voltage applied.

Not sure how to adjust them for your car. Usually there is a screw for it on top. You might have to remove some of the trim around the headlight to access it.
