To enhance the overall light of the rear lights in poor visibility conditions (for example, in the fog) the rear lights also have additional fog lamps 10 (see figure 122), which are switched on by the fog light switch 6. At the same time, the corresponding indicator lamp in the instrument cluster also lights up.
In addition to the side lights and fog lights, the rear lights also have reversing lights, brake lights and direction indicators. The reversing light is turned on by a switch located on the gearbox when reverse gear is engaged, if the ignition switch is in the "I" (Ignition) position. The brake lights are turned on by a switch installed on the clutch and brake pedal bracket when the brake pedal is pressed.
The cars are also equipped with a parking light. It can be turned on using the left lever of the steering column switch 8 (see figure 123), if the key in the ignition switch is in position "III" ("Parking"), instead of the direction indicators (which would turn on in a moving car) the parking lights on the left or right side of the vehicle are switched on.
Direction indicators. Lamps I (figure 124) turn signals in the headlights, lamps 9 in the rear lights, as well as side turn signals 2 are switched on by the left lever of the steering column switch 6 when the ignition is on. Intermittent burning of the lamps is provided by an electronic relay-interrupter of the turn signals and hazard warning lights, installed in the mounting block 3. The same relay switches on the control lamp of the turn signals in the instrument cluster 7 (left on the diagram) and the turn signal lamps are checked for proper operation. If any of the turn signal lamps do not light, the control lamp will flash at double the frequency.

The hazard warning lights are switched on by switch 8. In this case, all the direction indicator lamps light up intermittently at the same time. Flashing of the lamps is also provided by relay-interrupter 4. The operation of the hazard warning lights is monitored by a control lamp in the instrument cluster 7 (first on the diagram).
The hazard warning lights can be switched on in any position of the key in the ignition switch, since the voltage for the hazard warning lights, bypassing the ignition switch, is supplied directly from the power sources through fuse 11.
