CHECKING THE BULBS AND BULB SOCKETS
CHECKING THE CONDITION OF THE BULBS
The following procedure applies to all of the bulbs.
1. Remove:
• bulb
Since the headlight bulb gets extremely hot, keep
flammable products and your hands away from
the bulb until it has cooled down.
•
Be sure to hold the socket firmly when
removing the bulb. Never pull the lead,
otherwise it may be pulled out of the terminal
in the coupler.
•
Avoid touching the glass part of the headlight
bulb to keep it free from oil, otherwise 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:
• bulb (for continuity)
(with the pocket tester)
