The headlights are turned on by a switch installed on the instrument panel trim. The high and low beam headlights are on only when the ignition is on. When the ignition is switched off, only side light bulbs can be lit in the headlights. Switching the headlights from high beam to low beam is done by the lever of the left steering column switch.
To adjust the direction of the dipped beam beam, there are two screws with plastic handles on the rear wall of each headlamp. The screws allow you to change the direction of the light beam in the horizontal and vertical planes. The headlights are equipped with a hydraulic luminous flux direction corrector, which allows changing the vertical direction of the light beam from the passenger compartment in accordance with the vehicle load.
Some cars are equipped with fog lamps, which are mounted in the niches of the front bumper. The fog light switch is located in the instrument panel trim on the left side. When you turn on the fog lights, the control lamp next to the switch lights up. Headlights can be fitted with AKG 12-55-2 lamps (HI) or AKG 12-55-1 (NZ). The fog lamp relay is installed in the mounting block.
On a car not equipped with fog lamps, their installations are closed with plastic plugs.
On the outer sides of the block headlights, front direction indicators are fixed. They are equipped with A12-21-4 type lamps (PY21W) with bulbs of orange light. Turn signals are duplicated by side turn indicators (repeaters), mounted on the front fenders. Baseless lamps are installed in the side direction indicators. In this case, if the diffuser of the lamp is orange, then lamps of the A12-5-2 type are used (W5W), and if the diffuser is colorless, then - with an orange bulb type A12-5-3 (WY5W). The direction indicators are switched on by the left steering column switch.
On cars VAZ 2110 with a sedan body and VAZ 2112 with a hatchback body, combined rear lights are installed, which consist of two parts. One part - an external lamp, is installed in a niche of the rear wing and consists of two sections: the upper one - a section of a direction indicator with an A12-21-3 lamp (P21W) and lower - sections of marker and fog light. Two lamps are installed in the lower section: A12-21-3 (P21W) and A12-4-1 (T4W). The other part is an internal lamp, mounted on the cover (or doors) luggage compartment and also consists of two sections: a reverse light section with a colorless diffuser and a brake light section with a red diffuser. In both sections, the same type of lamps are installed - A12-21-3 (P21W).
On a VAZ 2111 car with a station wagon body, the interior lamp also consists of two sections with lamps A12-21-3 (P21W), but instead of a brake signal section, a fog light section is made. The outer lamp has three sections: the upper one - side light with A12-10 lamp (R10W); middle - braking signal; lower - turn signal. In the two lower sections, the same type of lamps A12-21-3 are installed (P21W).
A ceiling lamp is installed on the ceiling of the cabin. It turns on automatically when any of the side doors is opened by limit switches installed in the door openings, or by force when the diffuser of the ceiling is pressed. A lamp of type AC12-5-1 is installed in the interior lighting dome (C5W). The same lamps are used in license plate lamps, glove box and luggage compartment lamps. The license plate is illuminated by two lights. The lamps for the license plate lights and the luggage compartment light come on when the parking light is turned on. The luggage compartment lighting lamp can be forcibly extinguished, for which there is a switch on the ceiling itself. The glove box light comes on when the ignition is on and the glove box lid is open.
