The loss of a definitive cut-off is pretty typical for both HID and LED replacement bulbs. In my own case, beam pattern control was the worst with HID's and acceptable with LED's. Your color match with the turn signal switchbacks looks pretty good too.
I have a couple of questions for you...first, was a spacer supplied in the kit so that the retaining spring could properly secure the bulb? And second, do you use the stock rubber boot to seal the opening?
