Default Triple LED headlights shaking on bumps?

I noticed that when I hit a tiny bump or imperfection on the road, I can see the cutoff of the triple LED shake? My wife's regular RX doesn't do this.

Anyone notice similar issues?

not sure what you're saying exactly.

Simple physics means that if you go over a bump, everything else should bump with it haha.

Mine go up and down when I go over a bump

You can see the cutoff vibrate. Wife's RX with non triple led does not.
My last IS350 F-sport was bumpier than this and the cutoff never shook.

I hope I'm describing this correctly.

Hmm... Might be something loose! Open the hood, remove the plastic covering and check the housing. Jolt it with your hands it should be extremely solid. If not, something might not have been screwed in.

I tried that haha. Tightened up all the bolts I could reach and shook the housing but solid as a rock. Could the internal mechanism be causing this? This is my first forray into headlights that adjust as well.

I'm assuming its due to the auto leveling headlights so when you go up bumps it compensates because it thinks it's raised and when it lowers it moves back.
