I have spent 2 times using the standard rx pictures as to where the screws are 1 is as shown the other is in the back of the light assembly.
the diagrams I have seen online show one in a completely different place.

Happy New Year!

I'm hoping to adjust my headlights for better night time driving. I bought my 2007 recently and I think the headlight adjustment is different from what is described in the manual. One of the previous owners had replaced them after a minor front accident. Does anyone recognize these lights?


On the backside, there is something that looks like an adjustment screw/nut (circled):


My low beams currently point too low. If that is the adjustment screw, which direction do I turn to raise the lights?
Thanks much.

Here is a paraphrasing of the instructions from Lexus on how to do this, for anyone looking to do it themselves:

1) prep the vehicle (make sure tire pressures are within spec, all fluids at the correct level, make sure the spare tire and tools are in the trunk, make sure the care doesn't have a bunch of heavy stuff in the trunk or in the interior, make sure there is 150lb in the front seat - use a friend, bounce the suspension up and down to settle it)

2) park the car on level ground, squared up to a flat wall. Make sure the dot on the headlight lens (the plastic housing - there is a little dot on it, the measurements are from THAT point, and not the bumper or something) is 25ft from the wall

3) using the dot as a reference, use something to make marks on the wall: one down the centreline of the car, vertically. Make two vertical lines (on the wall) directly in front of the headlight dots on either side, and one horizontally at the level of the dots.

4) obscure the headlight on one side of the car such that only one may shine on the wall. You must adjust them independently.

5) start the engine, and turn the headlights on

6) make sure the upper part of the stepped cutoff line of the left headlight is on the horizontal line, and to the left of the centre line, and below and to the right for the right headlight

7) if they are out of spec, get a philips No. 02 screwdriver using the aiming screws on the upper corners of the backs of the headlight housings accessible from inside the engine compartment. Clockwise moves it up, anti-clockwise moves it down. Make sure your final turn of the screwdriver is in the clockwise direction to take any slack out of the adjustment.

How much do you turn it? Full turn or numerous turns

It only needs to be turned enough to line up headlight beam with the marks you make on the wall. There is no “standard” number of turns. Your headlights may still be correctly aimed, or maybe just one of them is out of spec, for example. There is no way to tell without this elaborate setup with distances and marks on a flat wall on level ground.

Thank you for the instructions. Unfortunately, I realized my car has some cheap aftermarket lights that a previous owner put in, so has a totally different, and limited, adjustment capability. I took it to 2 very experienced mechanics and neither could adjust them properly. We minimize driving at night in areas without street lights and/or use high beams. Fortunately we do have a 2nd car. Sigh.
