LAMPS

Headlamps

The lamps have the reflector
and glass sealed as a unit.
The bulb has a " pre-focus "
cap accurately located and
correctly positioned relative to
the reflector, thus no adjust-
ment to focusing is required
when a replacement bulb is
fitted..
It is not possible with these
types of lamps to alter the
direction of dip entirely by
fitting bulbs of the opposite dipping characteristics, as some of the dip effect
is produced by the shape of the glass in the lens.

Bulb Replacement

Remove the Snap-on rim by inserting the end of the special tool (provided
in the kit) behind the lower edge of the rim and levering sideways as shown
on Fig. 41. Press in the lamp unit against the tension of the three adjusting
screw springs and turn in an anti-clockwise direction until the key-slot holes
in the rim line up with the screw heads. The lamp unit can then be drawn off.
Do not rotate any of the screws, as this will affect the alignment of the
reflector when assembled.
Rotate the adaptor anti-clockwise and pull off, then the headlamp bulb can
be removed. (See Fig. 38). Care should be taken to see that the .bulb does not
drop out.

Lamp Alignment

The lamp must be set to ensure that the beam is not projected above the
horizontal, taking into account road inequalities and the normal loading
of the car.
