Headlights shake when hitting a bump

Is that normal? The beams just seem to shake or jiggle just a bit when I hit bumps in the road. Was wondering if it was on purpose to keep them from breaking. Any idea?

I think I've noticed this too. So it's probably normal.

It's normal. Mine does it too. It's due to the active headlights, because they swivel when you turn, there is a little movement when they take a jolt. Or at leas this is what I was told when I asked about it.

It's probobly partly because of the auto leveling feature as well. Sense xenons make such a crisp light line on the car in front of them sometimes you can see when they are slightly readjusting up and down to bumps or dips in the road or u hitting the breaks. It's a series of slight notches up an down and if you look hard enuf u will notice it. Not sayin that this is the reason for what u c but could be part of it.

It IS normal. After some miles... they will wiggle less. I think its the sensors being new and tight that causes the sensors to "bind" when new.

Thanks guys. I seem to notice it when I hit a "wash board" type of bump, not in gradual dips, so I assumed it was OK (i.e. hoped it was OK). I drove my wife's Acura with Xenons (not adaptive) and saw no movement over the same wash board, so it had me a little concerned.

It's normal but weird that I didn't notice this with my past BMWs that had adaptive xenons

Happens here too, and to speak towards ^; my previous BMWs with adaptive bixenons have all done it to some degree.

Try going over bumps with coilovers
It's normal. Don't worry too much about it
