Head and Tail Lamps
Used on Models G, J2, " 350 Bullet," " 500 Bullet," " 500 Twin,"
"Meteor 700," 1950 onwards
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.
