Quick Overview

  • Thankfully, adjusting headlights on a VZ Commodore is a relatively simple DIY task that can be done with basic tools and a little patience.
  • With your car’s headlights on low beam, use a piece of tape or a marker to mark the center of your headlight beam on the wall.

The Holden Commodore (VZ) is a popular and reliable car, but like any vehicle, its headlights can become misaligned over time. This can lead to reduced visibility at night, making driving dangerous. Thankfully, adjusting headlights on a VZ Commodore is a relatively simple DIY task that can be done with basic tools and a little patience. This guide will walk you through the process step-by-step, ensuring you can get your headlights back in optimal alignment.

Why Adjust Your VZ Commodore Headlights?

Properly adjusted headlights are crucial for safe driving at night. Misaligned headlights can cause several problems:

  • Reduced Visibility: Headlights that are too low will not illuminate the road adequately, while headlights that are too high can blind oncoming drivers.
  • Increased Risk of Accidents: Poorly aimed headlights can contribute to accidents by reducing visibility and increasing the risk of not seeing potential hazards.
  • Legal Issues: In most jurisdictions, it’s illegal to drive with improperly adjusted headlights, potentially leading to fines or even vehicle inspection failures.

Safety First: Preparing for the Adjustment

Before you begin adjusting your headlights, ensure you have the necessary tools and that you’re working in a safe environment:

  • Tools: You’ll need a Phillips screwdriver, a flat-head screwdriver, a tape measure, and a marker.
  • Safe Environment: Find a flat, level surface with adequate lighting. Ideally, use a garage or driveway with a wall or a building nearby.

Step-by-Step Guide: Adjusting Your VZ Commodore Headlights

Now, let’s dive into the process of adjusting your VZ Commodore headlights:

1. Park Your Car: Park your car on a level surface, about 10-15 feet away from a wall or building. Ensure the car is facing straight ahead.
2. Mark the Headlight Beam: With your car’s headlights on low beam, use a piece of tape or a marker to mark the center of your headlight beam on the wall. Repeat this for both headlights.
3. Measure the Beam Height: Using a tape measure, measure the distance from the ground to the center of the beam mark on the wall. This measurement should be approximately 25 inches.
4. Adjust the Headlight Level: Locate the headlight adjustment screws. These are typically located on the back of the headlight assembly. Use a flat-head screwdriver to turn the screws, adjusting the height of the beam.

  • Turning the screw clockwise will raise the beam.
  • Turning the screw counterclockwise will lower the beam.

5. Fine-Tune the Adjustment: Once you’ve made the initial adjustment, check the beam height again. Repeat steps 3 and 4 until the beam height is at the desired 25 inches.
6. Repeat for Both Headlights: Repeat the process for the other headlight, ensuring both beams are aligned at the correct height.
7. Test Drive: After adjusting the headlights, take your car for a test drive on a dark road to ensure the headlights are properly aimed and provide adequate illumination.

Additional Tips for Optimal Headlight Alignment

  • Professional Adjustment: If you’re unsure about adjusting your headlights yourself, consider taking your car to a professional mechanic. They have specialized equipment and experience to ensure accurate alignment.
  • Check for Damage: Before adjusting the headlights, ensure there’s no damage to the headlight assembly or the bulbs. Replace any damaged components before adjusting the headlights.
  • Regular Maintenance: Regularly check your headlight alignment and adjust them as needed. This will ensure you have optimal visibility and maintain your car’s safety.

Final Thoughts: Ensuring Safe and Efficient Lighting

By following these steps, you can ensure your VZ Commodore’s headlights are properly adjusted, providing optimal illumination and enhancing your safety on the road. Remember, properly aligned headlights are a crucial aspect of safe driving, especially at night. If you have any doubts or concerns, don’t hesitate to consult a professional mechanic.
