Hi, I have a 2001 C5 Z06, and it has HID light kit with projector headlights and when my car is in idle, my headlights have vibration, when I am touching the corner of the bumper which nears of the headlights, there is also vibration on the bumper, so it is affecting the headlight and vibrating it. How can I solve it? what can I do to stop that vibration. can it be related with engine mounts? thanks..
