How to Adjust Car Headlights: A Comprehensive Guide

“Bright headlights, long roads without worry” – This old saying still holds true today. Properly adjusting your car’s headlights not only ensures your safety but also the safety of other road users. So how do you adjust car headlights effectively? Let’s explore this in detail with XE TẢI HÀ NỘI.

Why Adjust Car Headlights?

Many drivers, especially new ones, often underestimate the importance of headlight adjustment. They think that as long as the headlights are on, it’s fine. However, this is a misconception.

Misaligned headlights can cause:

• Glare for oncoming traffic: Creating danger for both drivers and pedestrians, especially at night.
• Reduced visibility: Making it difficult for the driver to see, leading to accidents, especially on dark, foggy roads.
• Increased fuel consumption: Inefficient headlights consume more energy.

A Detailed Guide on How to Adjust Car Headlights

Adjusting car headlights is easier than you think, as long as you understand the basic steps:

1. Preparation

• Location: Choose a flat, spacious area with a wall or flat surface as a reference point.
• Tools: Marker pen, tape, measuring tape (if available).
• Time: It’s best to adjust headlights at night for better visibility.

2. Steps to Follow

Step 1: Determine the center of the headlights and the vehicle

• Stick tape on the wall, marking the center of each headlight and the center of the vehicle.
• Measure the distance from the ground to the center of each headlight and from the center of the vehicle to the center of each headlight.

Step 2: Adjust the headlight height

• Reverse the car about 7-10 meters away from the wall.
• Turn on the headlights, use a screwdriver to adjust the height adjustment screw until the light beam hits a point about 5-7cm below the center of the headlight.

Step 3: Adjust the beam angle

• Left headlight: The light beam should deviate to the right of the headlight center by about 10-15cm.
• Right headlight: The light beam should align with the headlight center.

Step 4: Recheck

• After adjusting, test drive the car at night to ensure proper alignment.

3. Important Notes

• Consult your car’s owner’s manual for the location and adjustment method of the headlight adjustment screws.
• If you’re not confident, take your car to a reputable garage for assistance.
