I am new to audi and I did a search for this but did not find anything. Is it normal for the HIDs to kind of shake a bit, like the lightbeam kind of almost vibrates? I have never had HIDs so i thought maybe this is what they do...

 

I don't know about the shaking. I dont believe mine shake unless I go over bumps. and the changing color could be bulbs burning out.

 

yeah i mean the car only has 33XXX on it so the bulbs are the right color, i have seen something about a bouncing headlight but what is considered bouncing? mine are more of a vibrate when i see it up against the wall or the car in front of me...might just be how HIDS are....i mean they work fine other then that boucing/vibrate type of action that happens
