Absolutely LOVE mine, and after properly adjusting the headlight beams, I get nobody flashing me. (people were flashing me BEFORE i put the HID's in because of how they are angled high from the factory.) went with 4500K color. Will do 6000K on the set I put on the Brabus. No real noticeable difference in visibility between the two, but 6000K is more blue in color. 4500K is almost pure white. Install was super easy, and in a couple of weeks I'm gonna pull the front clip off again and remount the ballasts. Will probably do my angel-eye mod at the same time, but I'm still working on the details with that setup. Trying to do something less obvious when the system is not on.
