When I first drove the car out of the lot , I notice my light would bounce up and down over bumps. My first thought was oh *****, I have a lose headlamps. The first thing I did when I got home is google the problem and it seems to be normal on the GS because of the AFS.
However, even with the AFS turned off, the bounce is still there. What gives? The RX also have AFS and the headlamps is solid.

that's just how it is on the gs. the bounce is due to the mounting i think, not afs in action

If ure projector is good, it shouldn bounce even with afs. My headlights dont bounce of bumps.

Do you have the AFS feature? From what I understand, GS with AFS all do this because of the mounting mechanic used for AFS.

Yes i do, that happend to me when i hit a huge bump and the projector was loose. I had it replaced under warranty. A good way to check is, come up to the headlight n hammer fist bang it on top of the headlight see if it moves around, if it does you need to replace the headlight.

So is it normal for the headlights to move on bumps? I thought this is normal.

HAMMER FIST, as make a fist as a hammer and bang it on the headlight come on guys!!!!!!!!!!!!!!!!!! i seen 3gs driving behind me and when they hit bumps their lights didn't shake, nor do mine. If you have warranty have it replaced if you don't learn to live with it.

Well this thread seem to suggest that it's normal.

It's not a hard shake or anything, just the cut off beam is moving up and down. I wish more people would input in this thread.....If there's a mechanical reason for this and is normal then okay. If this is not, then Lexus should fix it.

Mine have always bounced a little when going over bumps.
