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
99).
Removing the headlight bulbs (fig. 80-81-82-83-84)
Remove the instrument panel covers (see page 66) and
release the clamps (1) of the light cover (2) to reach the
E headlight bulbs.
L.h. Hi-beam light-bulb (fig. 81):
pull out the bulb cable (3) and disconnect the bulb from
the cable.
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.
