therefore, gives the driver a clear Indication that
the direction signals are working correctly.
It will be noted that in order to maintain the
desired rate of flashing (British Ministry of Transport
regulations, 60-120 per minute) the filaments of the
front and rear lamps are "pre-heated" via the
resistance wire during "out" period of the flash.
Headlamp Flasher Switch
(Later Models)
The direction indicator switch also incorporates
the switch for flashing the headlamps, this Is
achieved by moving the lever stalk towards the
steering wheel and In so doing an insulated spring
loaded plunger, operated by the Inner end of the
lever, is depressed to make switch contact so that
both headlamps Illuminate and will remain so until
upward pressure on the lever is released. When
the lever Is released the switch will return to the
OFF position under the Influence of Its spring and
the headlamps will extinguish.
Headlamp flashing can be accomplished irrespective
of the lever position, I.e., whilst using either direc
tion indicator.
CAUTION
ROOTES MANUAL WSH. 124
Section N (Elec. Equip.)
In countries where the headlamp flasher operates
on the main beam, it Is Inadvisable to use the flasher
continuously when the headlamps are already
In the "dipped" condition, as the excess heat
generated by both filaments will greatly lessen the
life of either the bulbs or lamp units, which ever is
appropriate.
When the headlamp flasher system Is functioning
correctly, each application of the switch lever In the
upward direction will illuminate both headlamps.
Should either headlamp ·fail to illuminate a check
is to be made to ensure that the connections
to the headlamp are secure, if on Inspection the
connections are found to be satisfactory the bulb
or lamp unit is to be changed for one which is
known to be serviceable.
In the event of both headlamps failing to illuminate
when the switch is operated, for the Alpine Ill and
IV, the circuit from the switch to terminal I on
the fuse unit is to be checked.
For the Rapier IV,
the circuit from the switch to the starter solenoid,
via the ammeter, is to be checked. If after test
the switch is found to be defective, it must be
renewed as the switch is irreparable.
