Default Headlight Adjustment LS460, need input please

Hey everyone,

I know there are two adjustment gears on each headlamp. My pass headlight was a bit higher than the driver.

The low beams beams are dead on now after doing the vertical adjustment (the adjustment gear further down), but when I went to adjust the horizontal, the only thing I noticed was the high beam shifting left to right slightly. I did not notice the cutoff line shifting at all on the low beams with that adjustment. You can also see the high beam projector slightly moving inside the lens, but not the low beam projector AFS lens assembly.

My question is, does the horizontal adjustment (front gear toward the top) only control the high beam left to right or does it adjust the AFS movement, or both? I pretty much left that part alone since i wasn't sure what it was actually doing.

The high beams pattern that looks something like this \_/ \_/ seems even and the "V's" have the same equal spacing

Side note, before doing this adjustment, I noticed that my left headlight AFS movement is very obvious when turning left, but when I turn right, the AFS movement from the pass side lens does not seem to do the same range of motion. I know that each headlight turns so many degrees, but I would think the left turns more with a left turn and the right turns more with a right turn essentially.

Thanks in advance for your input, sorry for the long post

i don't know much details on the horizontal adjustment

but in terms of vertical, the driver side is supposed to be a bit lower than passenger side to avoid glare issue on oncoming traffic

ok, thanks!! thats what I was thinking. that explains why the beams hit at same time when bending down to look below cutoff, yet the line on the wall shows the right side of the cutoff line is a little higher. So at least that part is good to go.

Now i just gotta figure out that other adjustment

I'm pretty sure that low/high beam are adjusted vertically at the same time. I believe most cars where highs/lows in the same housing are setup like this.

that is strange. so if you back your car out on a level surface and sort of bend down looking at the beams, the cutoffs hit you at the same time? if your cutoff is even, then i wonder what is up with your high beams. Is there a chance your one of your high beam bulbs are not seated just right in the housing? I am trying to still figure out exactly what the two adjustment screws do..I wonder if anyone has some sort of tech manual that explains how to properly aim LS460 lights?

Hi Cjitty,

When you make adjustment with the headlight, which direction you turn the screw moves the headlight up (low beam). I need to move both of my low beam headlight up as it is too low right now. Also, this is the screw makes the verticle adjustment (there are two screws to adjust the headlight according to the manual). Thanks.

Guys what are the dealerships for?? Let them sweat the details. I wouldn't even waste my time trying. Thats why I personally purchased another Lexus. Its not the handling ( GHod knows), its not the looks, its not the performance........Its for the amazing customer service. Indulge in it a little and don't bother yourself imho
