I have a 07 GS350 AWD with the Adaptive Lighting System. The headlights shake when I drive over expansion joints, pot holes and almost any rough pavement. Living in New England these conditions are found on every road. I have the original Dunlop RF tire which I believe is part of my problem. Dealer says every thing is fine. Turing off the system makes no difference. I haven't experience headlight shake since driving a rusted out Volvo in college! Has anyone else experienced this? Will different tires help? Any other suggestions? <_<
