Introduction
Modern cars are equipped with a large number of electrical devices that require high-quality service and correct operation. Sources and consumers of electric power in conjunction with wires and switching elements (switches and switches) constitute a system of electrical equipment intended for ignition of the working mixture in the cylinders of the engine starter motor starter, the luminous signals, ensuring traffic safety, road lighting, cab and body, sound alarm, supply of instrumentation accessories.
At present an increasing number of items of electrical and electronic equipment is used in vehicles. The engine ignition systems, lighting systems and road signaling vehicle maneuvers cannot work and start without them. The supervision of individual units and units of the car are unthinkable without them. A growing number of products are used to create comfort, electrical circuits become more complex.
The lighting system has a special place in the electrics of car, as the effectiveness of the autonomous lighting and alarm systems in the conditions of growth of motorization and the increasing role of road transport essentially determines traffic safety in the dark. Naturally, the standards for lighting characteristics are determined by the requirements of security and the existing traffic conditions either.
The lighting system is designed for operation of the vehicle in the dark. It includes headlights, sidelights, tail lights, taillights fog light, light of the license plate and trunk, interior lights, engine compartment lamp, instrument panel lighting lamp, head and foot switch, breakers and fuses.
Key words: lighting system, AVTOVAZ, lamps, electrics, switch, beam.

Since 1920, electric lights were used. Lights with incandescent lamps were spotlights that blind oncoming drivers. At the junction with the oncoming car driver had to tilt the lights down, using for this purpose a special lever with cable or hydraulic mechanism. Another way to reduce the glare was based on reducing the intensity of the glow lamps by reducing the heater current using the rheostat. But all these tricks distracted the driver, and did not allow to install the lights after the change to the starting position.
Individual lights and dipped beam were installed on more expensive machines. The power of these lights was different: for low beam was 30 W, for driving 50 watts. Angle dipped headlights beam was installed to illuminate the road ahead by 15-20 meters, while the distant light - 40-60 meters. This allows the driver to switch the headlights to the desired lighting mode that is much more convenient.
The power and range of light could be increased by using the development of Ivan Petrovich Kulibin in a parabolic reflector. Thus, light having a parabolic reflector and lens could cover a few hundred meters.
In future, manufacturers began to complicate the design of lamps. In 1925 Bosch first began to produce double-stranded lamp filament, one strand of which is used for the low beam and the other for long. The massive use of halogen lamps was having better performance and greater reliability. Since it became possible to reduce the weight of the batteries due to the appearance in the generator car, which carried the power of high-power light bulbs, and removed the need to recharge the battery problem at stations.
Changes in lighting accompanied by the introduction of new lighting regulations. In 1957 in Europe, asymmetrical light has been legitimized in which the light from the driver is closer than the light on the passenger side. This reduces the risk of blinding oncoming drivers and increases safety.
Conclusion
Lighting and light-signaling system is designed to illuminate the road, the transmission of information on the overall dimensions of the car, or alleged to maneuver, to illuminate the license plate, cab, body interior, instrumentation, trunk, engine compartment, etc.
Automotive lighting devices are required to provide necessary information in a wide range of distances and in all kinds of weather conditions, do not dazzle drivers in the dark either.
Every motorist should perform daily visual inspection of light-vehicle devices. This simple procedure allows early detection of failure of lights, "indicator" or other light device. If you find faults, it is necessary to carry out diagnostics of external light devices for troubleshooting.
