Headlight Shake


Recommended Posts

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? <_<

I think this is pretty much normal for a car that does not have the projector beams in a fixed position. Because of the parts that make them able to move up, down, and side to side; they will be subject to extra unintentional movements on rough surfaces. My IS has the AFS system and a few times on rough surfaces, usually being a rail road track...I have experienced this. But knowing the characteristics of the system I see that as being normal operation. And as you mentioned getting "softer" tires might help absorb some of the rough terrain of the roads...but I doubt it will help much.

You may be right. However, the headlights of my RX350 (also adaptive) don't 'jiggle'.

Yeah I must admit that the jiggle over expansion joints and normal rough roads seems a little unwarranted. There may be a legit problem with his car. I only have seen it going over VERY uneven roads such as a rail road crossings.

I live outside of Boston and travel on really crappy roads sometimes. No shake whatsoever regardless of the AFS begin on or off.

Something ain't right with your set up.
