I got the xenon lamps and they sort of adjust up and down when you turn the ignition on but I have not seen them point towards the road when I go over a speed bump. I dont know about slight bumpssince it is hard to tell, but they dont focus on the road when going over big ones.

When you go over a ripple in the road, something that would make the nose of the car move upwards, your lights also move upwards. With the xenons, that bright white light can be blinding to the other driver. The self leveling feature keeps the beam pointed straight as the nose of the car "bobs" up and down. Did you get these on your car?

I've just read as much as I could find Xenon headlights on the web. But what the heck does the "self-leveling" mean/do. What is the purpose of "self-leveling"?

Thanks!
