Best option I have spec'd for the car, the Xenons make me dribble sex wee. That trick that they do with the side movement and up/down movement at start up is well good, and as Gizzy says you do get lots of looks.
I can confirm mine do move as I'm turning corners and dip etc as i go up and down hills. I didnt have to set anything in the MFD maybe mine were already set.
