HEADLAMP (Continued)
• Igniter - The lamp assembly contains an igniter
(Fig. 25) that controls the voltage applied to the lamp
electrodes. The igniter uses the voltage supplied by
the ballast and momentarily steps up the voltage to
25,000 volts to start the lamp. Once ignited, it will
reduce the voltage to 85 volts.
• Lamp - The lamp (Fig. 25) contains electrodes
and xenon gas. The lamp takes about 10-15 seconds
of warm-up time to reach full operation. The light
appears blue during warm-up and then turns to
white.
