Toyota Yaris 2009 headlight beam shakes and is misaligned
Hello all, I don't talk much here. Lately I have this annoying problem. The driver side headlight beam shakes and appears to be protecting much higher than the passenger side.
When I adjust the projection height with the control on the dashboard, I can clearly see the difference. When I set it to 5, the passenger headlight projects really low (like usual, what it normally did before). But the driver side beam is much much higher. Like at the 0 height. When I set the control to 0, it projects really high. I have been getting complaints from pedestrians and other drivers. In addition to this, when I drive on rough surface, the driver side beam shakes up and down significantly. Its really annoying since I live in a 3rd world country and most of the road to my home is cobblestone and rough surface. I am not sure if its related or anything but a while back I noticed that my driver side parking lights was dull. When I opened the hood to check out the bulb, I saw that it didn't sit fully. I tried to tight it down but the one of the teeth that holds it in place was snapped. So I just applied a light sealer and put it back. But my curiosity kicked in I started fiddling around. I wanted to check if I could replace the main bulbs with LED ones I had bought for another car. I took out a component next to the parking light bulb and it wasn't the headlight. It was some kinda motor with a black stick thingy. I assumed it was the motor that controlled the projection height. Before I could dig further, something came up so i just put everything back and left it at that. What should I check now guys? Do you think I messed up the alignment and stuff? P. S. When I tap on the driver side headlight unit slightly I can see that I inner reflective element shakes. Edit 1: Typo Edit 2: Added more details Last edited by tamrat; 03-14-2017 at 01:50 PM.

To address the shaking issue I would check that the headlight assembly is still secured to the car. It's held on by three bolts which are attached to plastic tabs on the headlight assembly. If you car has been in an minor accident in the front the tabs can break. Also check that the headlight bulb is fully seated in the headlight assembly. The H4 bulbs have a little metal clip that locks the bulb in place.

Broken wobbly working bulb from 7" round headlamp
Broken wobbly working bulb from 7" round headlamp--metal base of the bulb had welds broken that attached it to a circular ring which located it in the lamp reflector. So it would give shaky light beams (high and low) with incorrect aim.
