Side lamp bulb holder
The headlamp is a unique unit to the SVX model. The headlamp is a Wipac unit with a reflector divided into parabolic
segments, with each segment having a different focal length. The headlamp uses a H4 60/55W halogen bulb which is
retained in the rear of the headlamp with a wire clip. The headlamp also houses the sidelamp which is located in a hole
in the headlamp lens. The side lamp uses a W5W bayonet fitting bulb which is located in a rubber holder. A harness
connector from the side lamp connects into the existing side lamp connector in the main wiring harness.
The RH headlamp unit is connected into the main wiring harness. The LH headlamp is connected to the main harness
via a link harness which also supplies power to the auxiliary driving lamps.
Where fitted, an electric motor mounted on the rear of the headlamp allows for the electrical adjustment of the
headlamp alignment.
The headlamp is secured to a metal mounting plate, which is attached to the fender, with 4 self-tapping screws.

Alignment adjustment screw
The auxiliary high beam lamp is unique to the SVX model. The lamp is located within the headlamp surround. Two metal
plates are a press fit into the surround and 2 pivot pins on the lamp locate in the plates which allow the lamp unit to
pivot up and down in a vertical direction. This allows the vertical aim of the lamp to be adjusted using a worm and
screw mechanism located on the lamp. The adjustment screw locates in a hole on a moulded boss on the headlamp
surround. A washer is fitted to the screw on each side of the boss and are secured with circlip. The two washers and the
circlip retain the screw in the boss, which allows the rotary motion of the screw to be transferred to linear movement of
the lamp allowing the alignment to be adjusted. The screw is accessible through a hole in the underside of the lamp
surround.
The auxiliary high beam lamp uses a H9 65W halogen bulb which is located in an integral holder. The holder is rotated
to lock or remove in the rear of the lamp unit. Access to the bulb requires removal of the headlamp surround.
Auxiliary High Beam Lamp Relay and Fuse
The auxiliary lamps are connected via the headlamp link harness. A high beam feed from the LH headlamp is supplied
from the link harness and activates a dedicated auxiliary high beam lamp relay which is located in the battery junction
box (BJB), adjacent to the battery. The relay and auxiliary lamp circuit is protected by a 15 Amp fuse located on the
side of the relay. Activation of the relay allows a direct battery feed to power the auxiliary lamps.
