Regardless of the position of the switch key 5, you can briefly turn on the main beam of the headlights by pulling the headlight switch lever 10 towards you, i.e., carry out a light signaling. This is ensured by the fact that the voltage on the light signaling contact of the switch 10 is supplied directly from the power sources, bypassing the ignition switch.
On some cars, a headlight hydraulic corrector is installed, which serves to adjust the angle of inclination of the headlight beam from the driver's seat, depending on the load on the car.
