The headlights should therefore be properly aligned so as not to dazzle other drivers, which can cause very severe road accidents or reduce visibility on the road. The aim should be checked at least once per year and when changing headlight or doing front-end body work. Lending makes a temporary rebound until a specialist fits the corrections. For models from 1996 and earlier, there are two spring-loaded adjusting screws: one attached at top for the up and down movement and another one attached at side for left and right movement. Subsequent models have a bubble level for the scope to make it easier to aim. To adjust them, first, park the car in front of a blank wall at a distance of 25 feet and make sure that the car's floor is horizontal. The vehicle centerline and the centerlines of the two headlights should be indicated using masking tape and a horizontal tape across the middle of the car's width should also be made for balancing purpose. It should be stationary and ideally not pulling a trailer, or towing any object, and the fuel tank should be between half-full and half-empty. For low beam adjustment at the center on the target wall, the high-intensity area is two inches below the horizontal line and two inches to the side of the headlight vertical line, from the path of the oncoming vehicles, while turning the screws. In the case where high beams are on, the high-intensity zone should lie just a little below the horizontal line. When the compromise is made, let it be in favor of the drivers, keeping low beam functioning. The headlights should also be aligned as soon and as often as possible, the best people to do this are technicians from the service department or station.
