What is the importance of aiming the headlights correctly on 2004 Nissan Xterra?

Question

Accepted Answer

The way you set up your Frotiner and Xterra headlights matters because it stops you from hurting oncoming drivers' eyesight while helping you see better on the road. Your headlights need adjusting at least once a year, or after installing new headlights or fixing collision damage up front. Most models have two adjustment screws, one for moving each headlight side to side and the other to move them up or down. Later models may just have this simpler setup for just moving each lamp up or down. You need a flat, empty space with a blank wall to properly adjust your headlights. Place masking tape to show the center of your vehicle, both headlights, and a clean wall's horizontal line. Make sure the car is 25 feet from the wall, level, with half-full gas tank, and empty of any heavy cargo. For setting low beam headlights, position the bright portion two inches below the straight horizontal line and two inches left of the vertical headlight marking. To work headlights at their best, make sure the bright area focuses directly under the horizontal line. When you need to make a balance choice, pick low beam lights to ensure drivers stay safe. Getting new headlights carefully aligned at the dealership service center right away is the smart thing to do.
