Adjusting the headlights

From a headlamp aiming depends on safe driving. Incorrectly configured front optics can cause an accident, it is dangerous not only for others but for the driver. Even when purchasing a new car to test how the light of his headlamp, or it threatens unclimbed safety standards. You can seek help from professionals who in a few minutes will set up everything right, but you can take control and own. Untuned beam of light from the car driver says lack of culture. As the operation of the light from the lamps gradually dim. This may be due to a malfunction of the generator and voltage regulator. When the battery is not charging enough or, conversely, too much of it begins to boil the electrolyte. From a strong voltage light bulbs burn out faster. Another reason for the dim light - dirty or corroded reflector or plaque on the inner surface of the bulb (with the lamp more than 50 thousand km of the emission efficiency is reduced by 20%). On modern cars headlights are sealed, there does not penetrate the moisture and dust, which greatly improves the light output. And earlier with moisture, corrosive, fought pouring into the spotlight of red brake fluid. Then began to use the least harmful Plexiglas nozzles on glass, but soon from these "points" had to be abandoned because they scatter the light beams and cause heating, followed by burning of the reflector. Each vehicle, depending on the year of its release, marks, and sometimes even a model, management control starts when light is in different places. Someone in the cabin, someone under the hood, etc., from this moment must be pre-read the book, instructions for the car. Before you begin setting up, check tire pressure (if necessary disappoint wheel, after which the machine can be raised slightly), check the lights (maybe they serve you is not the first year and they should be replaced by a new and more powerful) and glass. Machine need a little shake to activate the suspension parts and put the wheel man, about equal in weight with the driver - just do a full simulation of traffic on the road. It is best to begin to adjust headlights in a darkened room (usually the garage). The light from the headlamps to be discharged on a vertical wall with a lighter and a bit of a rough surface. The machine should take a horizontal position, perpendicular to the wall. Headlights is checked in turn until checked one headlamp, the other is covered dense opaque material. Adjusting headlights reached such a direction of light, the driver could see the road and not blinded by the light traveling towards the neighbor. Machine set at a distance of 10 m from the vertical wall and the headlights on. One headlamp dense material close to its light was not visible, make a mark and repeat the same with the other headlamp. Acknowledge the materials at hand (eg chalk) the places where lights are visible centers, and carry between them a straight line. Then draw the second and third line parallel to the first, lower at 12 and 22 cm upper limit beam must not coincide with the second line. In the presence of fog lamps to light the upper limit should not coincide with the third line. A point of intersection of horizontal and inclined sections of the light must be on 12 and 22 cm below the marks the center of the headlights. Another way - to set the machine on level ground, measure out 30 yards and put a mark (eg, bricks). Insert a dim, obscure one of them. In the second adjusting screws so that the boundary of light vertically to bring to the mark. Then repeat this with the second lamp. Then you adjust headlights so that the light beams from both lamps are not forked and joined in the middle.
