Headlights, sidelights, reversing lights, lamps for interior lighting, engine compartment, trunk, glove box, license plate and open door lights, fog lights, direction indicators - this is not a complete list of them,
Naturally, each of them has a specific purpose and it is necessary to ensure that none of the devices is idle.
Remember. Improperly adjusted headlights dazzle oncoming drivers and do not provide good illumination of the roadbed.
A young inexperienced motorist can drive for a long time with such headlights, believing that everything is in order.
There are a number of factors that affect the location of the headlights: tire pressure, the condition of the coil springs of the front suspension, the difference in the forces of the front and rear suspension springs. These factors are variable, so the position of the headlights must be constantly checked and adjusted if necessary.
The headlights are adjusted by setting the car on a flat area. In this case, the tires must have normal pressure. For this operation, you need a screwdriver and a special screen, which does not cost anything to do it yourself on a wall, a sheet of plywood or cardboard. The screen is marked depending on the model of the car (see «Vehicle instruction manual»). The headlights of VAZ-2101, VAZ-2102, VAZ-21011 cars are adjusted on one screen. One screen for both VAZ-2103 and VAZ-2106. Vehicles must have their own screens VAZ-2121, VAZ-2105 and VAZ-2107.
All other lighting and signaling devices are checked by inspection, preferably together, since, sitting in a car, it is difficult to see what is happening behind, in front or on the side, where the lighting and signaling devices are located.
