Review

The operation of the exterior lights is controlled by the light switch and the multifunction switch located on the steering column. The light control switch is a 3-position switch mounted on (left) side of the steering column. Sliding the switch forward to the first position turns on the power (from battery) side lights, tail lights, and license plate lights, regardless of the position of the ignition switch. Moving the light switch forward to the second position also energizes the headlight relay.

The steering column multifunction switch is located in front of the light switch on the left side of the steering column; it allows the driver to switch the headlight mode: high beam, low beam and headlight signaling. The multifunction steering column switch is powered by the headlamp relay, which is activated when the ignition switch is turned to position II.

4 position rotary headlight beam adjustment switch (with this system) installed on the instrument panel and allows the driver to raise or lower the headlight beam depending on the vehicle load. An electric motor mounted behind each headlight adjusts its position according to the movement of the switch.

The multifunction steering column switch is also used to control the direction indicators. Power is supplied to the multifunction steering column switch from the ignition switch through the hazard warning light relay. When the switch is moved to the left or right turn indicating position, its contacts are closed and power is supplied to the corresponding lights. In addition, power is supplied to the instrument panel to turn on the turn signal indicator lamp.


The hazard warning light button is located on the instrument panel; pressing it turns on / off the indicators at the same time (left) and right () turn. The hazard warning light button is continuously powered by the battery, allowing it to be used regardless of the position of the ignition switch. When pressed, the hazard warning light button provides power to the instrument panel, where the hazard warning light turns on.

The brake lights are operated by a brake light switch located at the top of the brake pedal. When the brake pedal is depressed, the switch contacts close and the brake lights are powered by the ignition switch.

The reversing light is switched on by the reverse gear switch, which is mounted on the gearbox. When reverse gear is engaged, the switch contacts close and the reversing light receives ignition power.

The operation of the fog lamp is controlled by the fog lamp control unit located under the right right-hand (RH) front seat. The control unit receives ignition power from the headlight relay on through the central fuse box (CJB). The control unit monitors the status of the fog lamp switch. When the switch is pressed, its contacts are closed and a ground loop is created. Having found a ground loop, the control unit supplies power to the rear fog lamp and to the instrument panel.

Model SVX (60th Anniversary)

The exterior lighting system on the 2008 SVX is as described above with the following differences:

• Tail lights LED type (LED)
• halogen reflector headlights with a complex surface shape and integrated position lamp
• Separate high beam headlights that work while driving
• new front direction indicators.

The headlight is a unique block for the SVX model. The headlight is a Wipac unit with a reflector divided into parabolic segments, each with a different focal length. The headlight uses an H4 60/55W halogen bulb, which is held in the back of the headlight with a wire clip. The headlight housing also houses a position lamp, which is located in a hole in the headlight lens. The position lamp uses a W5W bulb with a bayonet base, which is located in a rubber socket. The electrical connector from the side light mates with the existing side light electrical connector in the main wiring harness.

(Right) the headlight assembly is connected to the main wiring harness. (Left) the headlamp is connected to the main wiring harness with a jumper wiring harness that also supplies power to the auxiliary driving lights.

The electric motor mounted on the back of the headlight allows you to adjust the position of the headlight (with appropriate headlight).

The headlight is attached to a metal base plate with four self-tapping screws, which is attached to the fender.

The auxiliary high beam headlamp is a unique unit for the SVX model. This headlight is located in the frame of the headlight. Two metal plates are press-fit into the bezel and two axles on the headlight fit into the plates, allowing the headlight assembly to move up and down. This allows you to adjust the position of the headlight vertically using the worm gear located on it. The adjusting screw fits into a hole in the molded tab on the headlight bezel. The screw on each side of the lug has a washer that is secured with a retaining ring. Two washers and a retaining ring hold the screw in the boss, which allows the screw to rotate and set the linear movement of the headlight, thus adjusting its position. The screw can be accessed through a hole on the underside of the headlight bezel.

The auxiliary high beam uses a 65W H9 halogen bulb which is housed in an integral socket. The cartridge must be rotated to lock or remove from the back of the headlight. To gain access to the lamp, you must remove the headlight bezel.

Auxiliary High Beam Relay and Fuse

Additional headlights are connected via the connecting harness of the headlight wiring. Power is supplied to the left high beam headlight through the jumper harness, activating a dedicated auxiliary high beam relay located in the battery junction box (BJB), located next to the battery. Relay The auxiliary light circuit is protected by a 15A fuse located on the side of the relay. Activating the relay allows direct power from the battery to the auxiliary lights.

The front turn signal is a unique unit for the SVX model. The lamp is located inside the frame of the headlight, is exposed on two ledges built into the frame and is fastened with two self-tapping screws.

The headlight uses a PY21W Diadem bulb, which is located in a socket at the rear of the headlight assembly. The chuck has a built-in connector that allows connection to the main wiring harness using a short connector harness that connects the main wiring harness connector to the connector on the chuck. The cartridge must be rotated to lock or remove from the back of the headlight. To gain access to the lamp, you must remove the headlight bezel.

Rear LED lights

(LED) taillights are unique units for the SVX model. All lights look the same when off and have a white opaque diffuser. After activation (LEDs) light up in a color corresponding to the purpose of the lantern.
The two upper rear lights serve as taillights and brake lights. The interior lower lights are turn signals. On options (left) the outer rear light serves as a rear fog light, and (right) external rear light - as a reversing light. On the variant, the position of these two lamps is directly opposite.
