CHECKING THE BULBS AND BULB SOCKETS
WARNING
@
Since the headlight bulb gets extremely
hot, keep flammable products and your
hands away from the bulb until it has
cooled down.
@
CAUTION:
@
• 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.
