ROYAL ENFIELD 350cc and 500cc O.H.V. WORKSHOP MANUAL
Recent machines use lamps with red plastic
covers, either Type 529 (Fig. 7), which is a tail
lamp only; 525 (Fig. 8), which is a combined
stop and tail lamp; or 564 (Fig. 9), which is a
combined stop and tail lamp and reflector.
Access to the bulb is obtained by removing
the two screws which secure the plastic cover.
The correct bulb for the 529 lamp is either
Lucas No. 988 6volt 3 watt M.B.C. or No. 951
6volt 6 watt M.B.C.
The correct bulb for the stop tail lights 525
and 564 is either Lucas No. 352 6volt 3/18 watt
or Lucas No. 384 6volt 6/18 watt. The 3 watt or
6 watt filament provides the normal tail light,
while the 18 watt filament is illuminated on
movement of the brake pedal.
6 watt bulbs are now required by law in
Great Britain on machines of more than 250 c.c.
capacity.
Care must be taken that the leads to the stop
tail lamp are correctly connected, as the use of
the 18 watt filament on the normal tail light will
not only discharge the battery but could cause
trouble from excessive heat affecting the plastic
cover. At the same time, the 3 or 6 watt filament,
if used as a stop-tail light will be ineffective in
bright sunlight.
