Hi timzter. The lights begin to move if you're driving more than 15 clicks/hr, and they do move quite well, the passenger side for me anyways and not the driver side...hence the reason for the post :(
By the way, I just noticed that you have the 2010 ES350, I don't believe they have the AFS on your model.
Well, mine is the 2010 ES 350 with the $4,955 Nav++ package. If you go through the "Build your own Lexus" on their website, after you're done, this is what you'd see. and AFS is mentioned in the Summary, but I honestly don't really notice the headlights turning left/right as I make turns.
My appologies! I'm not sure why you don't notice the lights turning because it is quite evident on mine. There is a couple of buttons under the steering wheel that control the mechanism, maybe it has been turned off?
