  • Space of at least 25-feet in length.

Step 1: Leveling Your Vehicle

When you want to aim your headlights correctly, you should note that it involves measuring to get the right angling. To get it right, your car should be at the right level on a flat surface with a wall in front. In this step, remove any luggage from your vehicle, which can affect its weight. You should also ensure that your wheels are at the recommended pressure, preferably the manufacturer’s standards. Your gas tank should be half full, and if possible, there should be someone in the driver’s seat. Also, ensure that the headlight adjustment tool is at the zero mark. The car should be on level ground for the best results. You can try pushing it down to see if it is stable.

Step 2: Positioning Your Car

The next step involves positioning your car, where the front must face the wall. You now measure the distance to the ground from the headlights to ensure that they are on a flat surface. If you get varying measurements, you should reposition your car.

Step 3: Find the Headlight Axis

You have to find the headlight axis to make the right aim and angling. Turn on the regular headlights and mark the center of each lamp; a small dot will do. Be careful not to use the high beam light or fog lights as you may make errors. You should also mark the axis point on the wall with tape; a horizontal strip will do well in helping you with the plotting. Now measure the distance from the axis to the floor and transfer the measurements to the wall. Mark the right place.

Step 4: Backing Your Car and Aiming

You should now reverse the car 25-feet from the wall. Do not estimate the distance; use the tape measure instead and mark the spots on the floor. You can use a headlight aiming wall chart to help you understand most of the metrics involved in this procedure as it requires accuracy. Once you are at the correct distance from the wall, you can turn off the light and remove the ring around the headlights to find the adjustment screws.

Where are the headlight adjustment screws? Once you remove the ring from the headlight assembly, you will notice the two adjustment screws, one at the top and another on the side of the headlight. The top is for vertical adjustment, while the one on the side is for horizontal tuning.

Step 5: Adjust Each Light Separately

It is advisable to adjust each light separately. You turn on the lights and focus on one first, then the other. You can cover the different lights with a dark sheet or cloth to proceed smoothly. Use a headlight alignment tool to tackle the tuning. When tuning the lights, start vertically, where clockwise raises them, whereas counterclockwise lowers them. The top of the beam should be at the headlight axis on the wall. With the aim correct, focus on horizontal adjustments, where the intense part of the beam should be to the vertical line’s right.

Make the same adjustments for the other car light, and you are good to go. Fix ring back to the assembly and go for a test drive to see if everything is alright. This procedure is similar to aiming fog lights, meaning if your fog lights do not have a proper alignment, you can follow most of the steps highlighted in this guide.

Before adjusting the lights, make sure that you have a clean headlight. If it is not clean, the beam may appear distorted, leading to an inaccurate aim.
