This issue is on my '08 400h. So I am convinced that my right headlight does not turn while driving around a right turn. I see it perfectly on a left turn. The right light mechanism does the alignment when the lights turn on. The dealership says there is no issue. I drove my in laws '12 350 and within 5 minutes I saw the right headlight move on a turn. I believe there is an issue has anyone seen this or know of a test that the dealership overlooked. I know the right doesn't move as much as the left lamp but I swear it doesn't move while driving.

 

Mine doesnt move very noticeably during a right turn either. I think it`s just the way they are. If there was a fault in the system, it would flash the afs or some kind of light to let you know.

 

The left one moves more than the right one...

 

... because the light pattern is biased to the right, so the visibility to the right - even in the absence of movement of the right headlight - is better than to the left.

 

If you trade up to a Gen III or just test drive one at night, you'll notice a big difference. There is a light more turn angle from the right light at speeds above 20mph.

 

So i guess that is why I see it on my in laws but not on mine

 

I forget the exact amount (it's in my service manual and I'm not at home) but the left moves something like 15 degrees, vs 5 degrees for the right.

I had a 2010 RX350 as a loaner when the tranny was replaced in my 2006 RX400h, and the right swivels a lot more on the current generation than the previous.
