ROYAL ENFIELD 350cc and 500cc O.H.V. WORKSHOP MANUAL
Head and Tail Lamps
Used on Models G, J and J2,
1. Headlamp
In all the above Models the headlamp
incorporates the Lucas Light Unit MCF700. This
is either fitted into a lamp shell (see Figs. 1 and
2) carried on brackets in front of the facia panel
type of fork head and housing a switch, ammeter
and parking lamp, or, on later models, is built
into the Casquette fork head which contains twin
parking lamps as well as the ammeter and
switch. On machines fitted with coil ignition the
ammeter has a red central window with the
ignition warning light beneath.
2. Lucas Light Unit
The unit incorporates a combined reflector
and front lens assembly (see Fig. 3). This
construction ensures that the reflector and lenses
are permanently protected, thus the unit keeps
its high efficiency over a long period. A
"prefocus" bulb is used, the filaments of which
are accurately positioned with respect to the
reflector, thus no focusing device is necessary.
The bulb has a large cap and a flange, which
has been accurately positioned with relation to
the bulb filaments during manufacture. A slot in
the flange engages with a projection on the
inside of the bulb holder positioned at the back
of the reflector.
A bayonet-fitting adaptor with spring-loaded
contacts secures the bulb firmly in position and
carries the supply to the bulb contacts.
The outer surface of the lens is smooth to
facilitate cleaning. The inner surface is formed
of a series of lenses which determine the spread
and pattern of the light beams.
In the event of damage to either the lens or
reflector a replacement light unit must be fitted.
