Blo ..... n (uses
A blown fuse is indicated by the failure of all the
units protected by It, and is confirmed by examination
of the fuse, which can easily be withdrawn from the
spring clips In which It fits. If it has blown, the fused
state of the wire will be visible inside the glass tube.
Before renewing a blown fuse, Inspect the wiring of the
units that have failed for evidence of a short circuit or
other faults which may have caused the fuse to blow,
and remedy the cause of the trouble. This is essential
or the fuse Is liable to blow again on replacement.
Always use a fuse of the correct fusing value

THE HEADLAMPS
Each headlamp Incorporates a Lucas light unit,
which consists essentially of a reflector and front glass
assembly.
The bulb, which Is a Lucas pre-focus
type, Is located accurately in the reflector and Is
secured by a bayonet-fixed back shell which also pro-
vtdes the contact to the bulb. The design of the bulb
and of its holder Is such that the bulb Is correctly
positioned In relation to the reflector and no focusing
is
required when a replacement bulb is fitted.
It Is to be noted that the block-type lenses fitted
to later models are different on LHD models from
those on RHD models and that it is essential to fit
correct replacement glasses if the beam formation is
to be retained.

the dipping switch. Operation afthe dip switch extln-
gulshes the right-hand lamp and simultaneously

headlamps are fitted with double-filament bulbs.
Operation of the dlp-swttch extinguishes the main
driving beam in each headlamp and brings the dlpplng

SETTING THE HEADLAMPS
Lucas beam setter
All lucas Service Depots and many service agents
now include among their special testing facilities an
apparatus known as the Lucas Beam Setter. This is
a specially designed instrument by means of which
headlamps can be set with extreme accuracy, thereby
ensuring the maximum efficiency from the lamps.
You
