With your chalk or pencil, mark the exact height in the center of the tape to represent the center of your driving lights. If you have multiple driving lights, ensure each light’s center height is clearly marked. This will serve as a target for alignment in the subsequent steps.

Step 3. Prepare Your Vehicle:

Position your vehicle directly in front of the wall or garage door on a flat surface, ensuring it’s about 25 feet away from it. Ensure the car faces straight ahead with the headlights directed towards the wall. Engage the parking brake, turn off the engine, and ensure that the fuel tank is at least half full, as the weight can affect the level of the lights. Remove heavy items from the trunk or rear seats that may unbalance the car’s posture.

Step 4. Level Your Vehicle and Lights:

Check if your vehicle is level by using a level on the hood or roof of your vehicle. Any tilt can throw off the light alignment significantly. Adjust if necessary, and ensure that the driving lights are level. This can be done by adjusting the brackets or mountings that hold the lights in place. Once your vehicle and lights are perfectly level, you can begin the aiming process.

Step 5. Turn on the Driving Lights:

Now, turn on your driving lights without turning on the headlights. The lights should be the only illumination you are using to align them. Position yourself in front of the vehicle, at the same height as the lights, and check if the beams are both level and pointing straight forward. The light beams should be concentrated on the wall, with the brightest spot corresponding to the marks you’ve made with the chalk or pencil. If the rays are not in alignment, you’ll need to adjust the lights.

Step 6. Adjust the Lights:

Locate the adjustment screws or knobs on the back or side of the driving lights. These controls allow you to move the light beams vertically and horizontally. While watching the beam’s position on the wall, carefully adjust the screws to align the lights. The top of the most intense part of the light beam should correspond with the line marked on the wall. The goal is to have the light rays hit the marks without rising above or falling below them, providing the optimal angle for visibility and safety.

Step 7. Check for Evenness:

Once the driving lights are adjusted to the marks on the wall, it’s essential to ensure they are evenly aligned. Both lights should be pointing at the same angle and height. If one light is higher or more to the side than the other, it can cause uneven illumination on the road, which can be both distracting and dangerous. Re-check the measurements and use the level to confirm that the setup is even before moving on to the final checks.

Once the driving lights are aligned and even, it’s time for a test drive. Choose a safe area to drive at night to assess the effectiveness of your adjustments realistically. Pay attention to how the driving lights illuminate your path, checking for any shadows or dark spots on the road. Be mindful of how your lights interact with oncoming traffic. If the lights are too high, they can dazzle other drivers. Adjust them as necessary to ensure you’re not impairing the vision of other road users while maintaining optimal visibility for yourself.

Step 9. Refine Your Adjustments:

After your initial test drive, minor tweaks may be needed to perfect your driving lights’ aim. Factors like uneven road surfaces or your vehicle’s load can impact light direction. If you’ve observed areas that need improvement, make the necessary refinements. Adjust the beams slightly downward or to the side to fill gaps or reduce glare for oncoming vehicles. Remember, the optimum setting for your lights will provide a clear view of the road ahead without blinding other drivers. Repeat the test drive as needed to confirm that your adjustments are precise and effective.

Step 10. Finalize and Document Your Settings:

After you’re satisfied with the placement of your driving lights following the test drives and refinements, it’s essential to finalize your settings. Tighten any adjustment screws or bolts to secure the lights in their correct position, ensuring they won’t move or vibrate out of alignment during your travels.
