Frequently Asked Questions (FAQ)

In general, headlights should be aimed so that they illuminate the road ahead without causing glare for oncoming traffic. The best way to adjust your headlights is to park your car on level ground in front of a wall or other flat surface, then measure the distance from the center of the headlight beam to the point on the wall where it hits. From there, you can adjust your headlights up or down until they are at the correct height.

There’s no need to call a mechanic every time you need to adjust your headlights. With a few simple tools, you can do it yourself in just a few minutes.

First, park your car in front of a flat surface like a garage door. Then, turn on your headlights and measure the distance between the center of the headlight beam and the ground. The ideal distance is about four inches (10 centimeters).

If your headlights are pointing too high or too low, you can adjust them using the adjustment screws on the back of the headlight assembly. To raise the headlights, turn the screws clockwise. To lower them, turn the screws counterclockwise.

It’s important to get the adjustment just right. If your headlights are pointing too high, they may blind oncoming traffic. If they’re pointing too low, you won’t be able to see the road as well at night.

With a little patience and some trial and error, you can adjust your headlights yourself without having to pay for a mechanic to do it.

You should adjust your headlights so that they shine no more than about 500 feet ahead while on a low beam. This will provide you with the best possible visibility without blinding oncoming traffic.

High beams should be aimed so that they do not shine directly into the eyes of oncoming drivers. Instead, they should be angled so that the light reflects off the road ahead, providing better visibility for the driver without causing glare for oncoming traffic.
