Replacing bulbs
Before replacing a burnt-out bulb, make sure that the new
one complies with voltage and wattage as specified on the
Electric System for that lighting device (page 70). Always
test the new lamp before refitting the parts you have
removed.
Headlight
Loosen the lower screw (1) securing the rim/reflector unit
E
to the body to gain access to the headlight bulbs.
Detach connector (2, fig. 45) from headlight bulb. Release
the clip (3, fig. 45) that holds the bulb in place and take the
bulb out of its socket.
Note
Be careful to hold the new bulb at the base only.
Never touch the transparent body with your fingers or it
will blacken resulting in reduced bulb brilliancy.
