Headlight adjustment Riga-Latvia

What is headlight alignment?

Correct headlight alignment is essential. The headlamp leveling is designed to ensure the correct dispersion of the headlights. So that the light does not blind the drivers of oncoming traffic and correctly illuminate the road.

Typically, headlight adjustment changes slightly during operation. However, when the vehicle is heavily loaded, the headlights must be adjusted, otherwise they will “illuminate the trees” in the high beam and blind oncoming drivers in the near beam.

Every driver knows that it is safe to drive in poor lighting conditions, such as late hours of the day or different weather conditions, only with properly adjusted headlights. If the headlights are incorrectly adjusted or completely absent, you can dazzle the drivers of cars who are moving towards you with the light flux. In this situation, there is a high probability of a collision of cars, as well as poor-quality operation of the headlights, which reduces the visibility zone, increasing the risk of an accident. Therefore, the driver is obliged to do everything to ensure that he has a full view of the road.

Car headlights are a very important part of the entire vehicle. They provide the good visibility you need at night. Every car enthusiast needs to check the serviceability of signal lights from time to time. Be sure to pay attention to each lamp and the cleanliness of the glass.

What is headlight adjustment for?

While driving, the car cannot avoid collisions with various road defects. Because of this, after a certain period of time, the factory setting of the optics is violated and requires the elimination of the breakdown.

It is also necessary that the angle of inclination of the headlights be able to be adjusted in the event of any of the following situations:

  • Mounting of fog lights;
  • Change of tires or discs;
  • Adding new suspension parts or making repairs;
  • Renewal of a lamp, headlight or its reflector;
  • Breakage of the headlight range control;
  • Replacement of lamp types – from incandescent lamp to LED or xenon headlight;
  • In the event of an accident, if, as a result, there was damage to the front half of the car body.

Types and types of headlights in the car

Lighting system

The lighting system ensures the operation of the car at night. It ensures the safety of the vehicle and has a brake light, direction indicator and reverse warning light. All parts of the lighting and light signaling system are powered by a storage battery or generator and are connected by wires.

Depending on the location of the headlights, there are front and rear, but it is the former that are considered priority. By their functionality, they are divided into several classes:

  • high beam headlamps capable of providing comfortable light at a distance of up to 300 meters, even at high speeds;
  • low beam optics, which shine brightly (up to 50 meters), but only in a limited space;
  • fog lights, which are additional lamps used in bad weather conditions; their main disadvantage is that such car headlights, the types of which may be different in design, when used with dipped beam headlights, greatly blind other drivers;
  • daytime running lights – they help to additionally mark the car in poor visibility conditions;
  • side lights installed both front and rear.

According to the principle of operation, car headlights are divided into 3 groups –

  • halogen
  • xenon
  • LED.


This type of automotive optics is considered the most popular due to the simplicity of the principles of operation and the large range of prices per kit. That is, you can pick them up for any budget, which is very popular with car owners. For this reason, they are often equipped with cars directly on the conveyor, although in terms of color temperature and brightness, halogens are inferior to more modern LED and xenon headlights.

The name of the headlights comes from the light source, which is a lamp filled with halogens of various gases. That is, in essence, it is simply an improved version of the incandescent lamp used for side lights and headlights. As for the head optics, there are several of its varieties – combined and divided. The divided one uses 2 halogen lamps with one filament, allowing you to switch the light from low to high and vice versa. In the second case, there are two incandescent filaments, but one lamp. However, this also allows you to effectively switch lighting modes.

Now in car dealerships you can buy halogen headlights with increased light output achieved by adding xenon to the gas mixture. Moreover, you can generally replace halogens with xenon optics, since the two types of optics have universal bases. However, it is not worthwhile to carry out such alterations on your own, since in the absence of appropriate documentation, the owner of the car faces a fine.


These types of car headlights have a large number of constituent elements, but they have improved characteristics. However, to install xenon, you need a lot of space under the hood, and this should be taken into account. Probably for this reason, such optics are mainly mounted on premium cars, and the high price for a standard kit also plays a role. But in comparison with halogen, xenon has its own advantages:

  • low power consumption;
  • different color temperatures, from standard yellowish-white light to bright blue;
  • extended operational period – over 3500 hours;
  • the possibility of using a plastic diffuser, since this type of headlights practically does not heat up.

Among the few disadvantages of using xenon optics is the mandatory use of washers and correctors. If you do not follow this rule, then the light will be of poor quality, and a trip in the dark will be dangerous. In addition, the headlamp requires an ignition unit for operation, although this, in general, cannot be considered a disadvantage. It’s just that this fact complicates the design of xenon optics, and the more components it contains, the greater the risk of breakage. Finally, the xenon kit requires skilled installation along with painstaking adjustments.


Such headlights have appeared relatively recently, but they have already won recognition among motorists as the best lighting elements. But they are not installed by all car manufacturers as head optics, although the principle of operation of lamps is the same for all. Moreover, it should be borne in mind that LED headlights and LED lamps are not exactly the same thing. The difference is very simple: the lamps have a base that fits many car models, but the headlights do not. Accordingly, if the headlights break, you will have to order a new kit, which is not cheap at the moment. True, the price of these products is gradually decreasing, but not as quickly as many car owners would like.

Unlike halogen and xenon lamps, LEDs do not dazzle oncoming drivers, although they shine in a bright white color. In addition, the level of energy consumption is several times lower in comparison with analogs. Plus, thanks to the waterproof and shockproof design, the LED bulbs can last over 10,000 hours. Finally, each LED has its own reflector that is positioned at a precise angle. And this leads to the fact that the light beam is not scattered to the sides, as is the case with halogen headlights.

  • The purpose of the fog lights can be understood from their name. This lighting is used to create visibility in bad weather conditions such as rain or fog. Another type of lighting will not help in this case, so the presence of fog lights provides a full view of the path in bad weather.
  • In order to improve the view of objects located at a distance of 120-150 meters, high beam headlights are used. They are necessary to see road markings or signs from afar. This type of lighting is forbidden to be used in settlements, as the light from it is too bright.
  • The low beam headlights are designed to illuminate the path in front of the vehicle at a distance of 20-40 meters. They need to be adjusted so as not to dazzle drivers who are moving towards you. This type of lighting is most often used, since the use of high beam headlights is prohibited in some settlements.

The lighting system also includes:

  • sidelights,
  • taillights,
  • instrument panel lighting lamps,
  • interior lighting of the cab or body, main and foot switches,
  • dashboard and cockpit lamp switches, fuses and wires.
  • in some cars, in addition to the headlights, a spotlight is installed in front, which allows you to direct the beam of light in the required direction
