Headlight vibration

Hi everyone, I have a slight vibration on my pilot headlight (bixenon), I have already secured bolts and the lower part of the casing because it was a little bit loose.

I've noticed that when I smash the headlight softly with my fist, the projector is somehow loose. When I drive this vibration is very evident on the road.

Is there any adjustment that can be done inside of the casing for the projector? I don't want to mess something with the autoleveling.

Any help would be appreciated.

Well, hit it on the upper part, you know what I mean.

I misunderstood - I thought the light bulb was loose - but you are saying that the projector is loose. - I suggest taking it apart - find the DIY for angel eyes and use that info to take the light apart so you can remove the chrome shroud and check for something loose.

Thank you, will try that way!
