If your headlights are improperly aligned, they can either blind oncoming drivers or fail to illuminate the road effectively. To determine if your headlights are too high or too low, you can conduct a simple test and make adjustments as needed. Properly aligned headlights enhance visibility and ensure safety on the road.

How to Check if Your Headlights Are Aligned Correctly

To ensure your headlights are properly aligned, follow these steps:

1. Find a Level Surface: Park your car on a flat, level surface facing a wall or garage door, about 10 to 15 feet away.
2. Mark the Headlight Center: Use masking tape to mark the vertical and horizontal center of each headlight beam on the wall.
3. Back Up: Reverse your car straight back about 25 feet while keeping your car aligned with the wall.
4. Check Alignment: Turn on your headlights and observe the beam pattern. The top of the brightest part of the beam should be at or just below the horizontal line you marked.

Signs Your Headlights Are Too High or Too Low

• Too High: If the beam is above the marked line, your headlights are likely too high, which can blind other drivers.
• Too Low: If the beam is well below the line, your headlights might not illuminate the road sufficiently.

How to Adjust Headlights

Step-by-Step Headlight Adjustment

1. Locate Adjustment Screws: Open the hood of your vehicle and find the headlight adjustment screws. These are typically located on the top and side of the headlight housing.
2. Adjust the Vertical Aim: Use a screwdriver to turn the vertical adjustment screw. Adjust until the top of the beam is even with or slightly below the marked horizontal line.
3. Adjust the Horizontal Aim: Turn the horizontal adjustment screw to center the beam with the vertical line.
4. Test Your Adjustments: Drive your vehicle to ensure the headlights are properly illuminating the road without causing glare to oncoming traffic.

Why Proper Headlight Alignment Matters

Proper headlight alignment is crucial for several reasons:

• Safety: Misaligned headlights can reduce visibility, increasing the risk of accidents.
• Compliance: Many regions have regulations regarding headlight alignment. Improper alignment can lead to fines or failed vehicle inspections.
• Driver Comfort: Properly aligned headlights reduce eye strain and improve night driving comfort.

Common Causes of Misaligned Headlights
