CHECKING THE BULBS AND BULB SOCKETS
WARNING
WARNING
Since the headlight bulb gets extremely
hot, keep flammable products and your
hands away from the bulb until it has
cooled down.
CAUTION:
ACHTUNG:
• Be sure to hold the socket firmly when
removing the bulb. Never pull the lead,
otherwise it may be pulled out of the ter-
minal in the coupler.
• Avoid touching the glass part of the head-
light bulb to keep it free from oil, other-
wise the transparency of the glass, the
life of the bulb and the luminous flux will
be adversely affected. If the headlight
bulb gets soiled, thoroughly clean it with
a cloth moistened with alcohol or lacquer
thinner.
2. Check:
