HEADLAMP
DESCRIPTION
The
headlamp,is of the sealed beam unit
type
and
access
is
gained to the bulb
and
bulb
holder
by'withdrawing the
rim
and
beam
unit
assembly.
To do so, slacken the
screw
at
the
top
of
the
headlamp
("8"
Fig.
H15),
and
prise
off
the
rim
and beam unit assembly.
The
bulb
can
be removed
by
first pressing
the
cylinderical
cap
"D" inwards, and turning it
anti-clockwise. The cap can then
be
with-
drawn
and
the bulb
is
free to be removed.
When
refitting a new bulb, note
that
it
locates
by
means
of a cutaway and projection
arrangement.
Also
note
that
the cap can only be replaced
one
way,
the
tabs
being
staggered
to prevent
incorrect reassembly. Check the
replacement

bulb voltage and

specification and
type
before fitting. Focusing with this
type
of
light unit
is
unnecessary and
there
is
no
provision for such.
A parking,
or
pilot bulb "E"
is
also used, being
a
"push-in"
fit
in
the reflector.
BEAM
ADJUSTMENTS
The
beam
must
in
all
cases
be
adjusted
as
specified by local lighting regulations.
In
the
United Kingdom the Transport Lighting Regu-
lations read
as
follows:-
A lighting system must be arranged
so
that
it
can
give a light which is incapable of dazzling
any
person standing
on
the
same
horizontal
plane
as
the
vehicle
at
a greater distance
than
twenty
five
feet
from the lamp,
whose
eye
level
is
not less than three feet-six inches
above
that
plane.
The
headlamp
must therefore be
set
so
that
the
main
beam
is
directed straight
ahead
and
parallel with
the
road when the motorcycle
is
fully loaded. To achieve this, place
the
machine
on
a level road pointing towards a wall
at
a
distance
of
25
feet away, with a rider
and
passenger,
on the machine, slacken
the
two
pivot bolts eitherside of the headlamp
and
tilt
the
headlamp until the beam
is
focused
at
approximately two feet six inches from
the
base
of
the
wall.
Do
not forget
that
the
head-
lamp
should
be
on "full-beam" lighting during
this
operation.
