I've noticed that when I drive behind someone at night with the headlights on, my headlights vibrate, shutter & shake especially on rough roads. Not much, just enough for it to be noticable. I know the headlights adjust depending on suspension level, but this shaking cant' be normal. Is it?

My 04 C5 A6 Avant (with Xenon+) has the same thing, I think it's normal.

the sharp horizontal cutoff in your xenon lights. Completely normal.

Make sure the headlight inner assy isn't loose, or bulb may go out BTDT

...which is really hard to do with the headlight mounted to the car ...seriously.

See my sig for my oem hid upgrade....lots of related links/posts...that will be useful.
