ROYAL ENFIELD 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.
