I didn't do a very in depth how-to regarding this, since it had been done before. I know there's one in the how-to section, but I don't believe it details how to remove the bumper and take the fogs out.
As for adjustment, on the MS6, we have a 3-position motor that is controlled inside the car, not sure if the US built 6s have that. I don't think you can adjust any headlamps left or right, just up and down. There should be the typical mounting screw on the top of the headlight housing to adjust. Just park in front of a wall or garage door and adjust until you're happy. Keep in mind they will come pre-aimed with the drivers side slightly lower than the pass. side.
thanks. The US models have (or at least mine) two screws to aim them. And I was wondering why the driver side was a bit lower than the passender, thanks for helping me out.
