I spent something close to 400 for the ballasts, bulbs, & tsx projectors and put it in my jdm headlights. After doing the retrofit, I would say it could fit in the USDM the same or better. Even though the headlamp glass messes up the crispy cut-off line that would exist without it, this should not be the main reason to switch in the first place...the intensity and area covered with light on the road is just sooooooo much better than the blot the stockers put out, and this is just with a 35w ballast, with the "55"w the intensity would noticeably increase although shortening the bulb life.
