Headlights shake or flicker with even the slightest bump in the road. It will even do it if you close your door hard. GM is aware of the issue on all their trucks but has no fix nor do they plan to. They simply blame it on the HID bulb but I have other cars with HID bulbs that do not do this. I have also been in several cars with HID bulbs and none of them do this.
