How to adjust Head lights of your car?

Head Lamps or Head lights

Safe driving is dependent on our ability to react to any situation, but we can only respond to what we can see. Low beams and high beams are our first line of defense against poor visibility, but often their range falls short. Driving lights pick up the slack. They're designed to boost the intensity and range of your high beams, showering the roadway with brilliant light. When we can see clearly, we're able to rapidly respond to whatever may come our way.

If you think about it, driving lights give you the power to peer into the future. All their extra light reveals the road that lies ahead of you, and you can use that knowledge of upcoming conditions to plan your next course of action. Without the foresight that driving lights deliver, your ability to respond to hazards is greatly diminished. Because of this special characteristic, driving lights are most effective for nighttime highway driving because of the higher cruising speeds.

Driving lights generate beams that are more focused than fog lights because they're engineered to travel farther in advance of your vehicle. As such, correctly aiming them is crucial to improve your own visibility while avoiding blinding other motorists. Follow these S.A.E. tips to properly align your driving lights.

Mount your driving lights on the front of your vehicle 14"–30" up from the ground.
Park 25' away from a flat wall, like a garage door or the side of a building. Level ground gives you the most accurate results.
Measure the distance from the center of your driving light down to the pavement, and mark that distance on the wall with chalk.
Flip on the lights and find the center of the hot spot, which is the intense inner circle of the beam. Tilt the driving light so that the center of the hot spot is 1 " below the mark you made in the wall.
While there is little variation in the beam pattern, driving lights come in a number of different styles that are optimized for specific driving conditions
