Default 2000 ls400 auto leveling lights going too high

i checked and the rear rod is broken, but regardless where I set the arm to manually the lights still go up way too high. I lowered them some with the manual adjusters but the auto level just swings them way too high, im fully illuminating overpass signs. How can I limit how hih the auto level swins the lights up?

Mine had the same issue, I just took it to the dealership and they fixed it. Turns out mine were over an inch too high.

My rear arm broke as well.
I tried zip tieing it and the rod would work its way down while driving. Here is what I did.

With the car parked. I had mine running with the lights on. Adjust the rod to get the aim somewhat level.

Then I disconnected the the wires going to the level motors on the headlights.

Now by doing this, it will trigger a idiot light indicating a fault with the level system. So I plugged in a spare set of level motors and left them hanging.


One of these days I'll re weld the rear linkage. But for now. I don't get high beamed and no idiot light.

cool, so you actually saw the position change as you messed with the sensor?
I need to figure a way to get my hand in there to grab it, cars too low normally.

I need to get this done also since my lights are literally pointing straight down at night. I want to adjust it at the headlight but you have to do it at night and is kind of difficult to do the drivers side with the battery in the way.

I find i can do the driver decently if i remove the battery bracket. Still a little tough to get in. i know they make special wrenches for headlight alignment, super slim prolile and about 8" long. Saw a 7mm one on rockauto for 1.50, but we need 8 mm head.
On my passenger headlight, the middle manual adjuster is stripped, so you cant actually adjust it-and if you do the first big bump will disloge it and then the whole assembly shakes and flickers. I had to run a nut down so its pointed low now (at least its not up 20 feet like before. I would watch p-eoples faces cringe and melt in their side view mirror, SORRY!)
Really hoping messing with the adjuster arms I can get it to a good height. .

You probably need to make custom links that are longer/shorter than stock depending on how they are positioned.

Yeah not much room with an 8mm socket on a ratchet. Plus the wiring being in the way. I wondered if Lexus had a SST for the adjustment.
