How to Adjust Headlights for Your Lexus

If you are a proud owner of a Lexus automobile, you would know that most (if not all) of Lexus cars are delivered with the HIDs aimed way low. So low that, on a dark road, you can't see more than 50 feet ahead of the automobile.

The headlights abruptly come to a halt, and it's pitch black. This is not a good sign at all while driving on a highway. That’s why you need to know how to adjust headlights for your Lexus and I have you covered.

In this step-by-step tutorial, you’ll be learning to adjust the HIDs of your Lexus car at home by yourself and you won’t be costing a fortune at all.

The low and high beam headlights on Lexus vehicles have lateral and vertical adjustable knobs. They have an adjustable gauge on the headlight assembly that indicates the allowed range of direction for the beams.

This makes changing the aim of the Lexus headlights quite easy. It’s because you do not have to build your custom target or set up the necessary settings for adjusting the headlights.

Unlike you had to do with most other automobiles from the first decade of the millennium.

Things You Need to Adjust Your Lexus Headlights

  • Your Owner’s Manual: The manual you got when you purchased your vehicle, will show you where the adjustment screws are and what type of are they.
  • A Screwdriver: A Phillips flat head screwdriver would be the best for this case.
  • Dark cloth or cardboard: A piece of dark fabric or any cardboard to block the light of one headlight while adjusting the other.
  • Masking Tape or Markers: To mark the desired height level you want to reach the lights of your headlights.
  • A Measuring Tape: To measure the lines to mark your headlight heights.
  • A garage door or a wall with at least 25 feet of clearance.

Adjusting Your Headlights: A Step-by-Step Guide

Prepare Your Vehicle

Find a place that is sufficiently enough dark for you to conduct the adjustment of your headlights. Park your car facing the wall and use the measuring tape to make sure there’s 7.62 m (25 ft) of space between your Lexus and the wall.

There should be a cutoff line on the wall below which headlight beams can be detected, and above which it cannot. Also, make sure the vehicle is at a 90-degree angle with the wall.

Prepare Headlight Inspection Wall

Mark a vertical line on the wall aligning with the center of the vehicle. A horizontal line must also cross the center marks while marking them.

Check where the low beam headlights marked the beam centers and make sure the horizontal line is at the same height as that center.

You need to intersect the horizontal line at each center mark aligned with the center of the low-beam headlight bulbs with two vertical lines drawn. These marks serve as a target for the headlight beams.

Headlight Aim Inspection

Turn off the headlights. Use the dark cloth or cardboard to cover one of the headlights so that when you work on adjusting one headlight the light of the other one doesn’t interfere in the adjustment process. Open up the hood of your car. Start your engine to start the process of headlight adjustment.

Adjust Your Headlight Aim

Take your owner’s manual and locate the low beam headlight’s adjustment nuts. You’ll find that the headlight assemblies on your Lexus include two adjustment screws for lateral and vertical aim.

These screws are located at the back of the headlight assembly, but holes on the top of the assembly allow you to access them without needing to disassemble other parts of the vehicle.

Adjust the aim of the headlight by turning the aiming screw with the flat head screwdriver. When you spin the aiming screw clockwise, the headlight aim travels higher, and when you turn it counterclockwise, it moves down.

Continue to make the vertical and horizontal adjustments until the center axis of the headlight beam aligns with the marks on the wall.

Final Notes

That’s all. Now you just need to take the car for a test drive once you're satisfied with the modifications, and if one of the headlights isn't working properly, repeat the steps above.
