Just so you know, the X5 comes with an uneven headlight setup. The driver's side headlight is adjusted to be slightly lower so that it doesn't blind oncoming traffic. If you shine your headlights against a wall, they will not be even.

I'm not saying that you can't set them up even. I'm just letting you know what the factory setting is so that you won't think that that your lights are not aligned correctly if you notice this.
