Pacifica V6-3.8L VIN L (2005)
Headlamp Bulb: Description and Operation
Quad headlamps are standard equipment on this model. They are halogen headlamps, both low and high beams.
Hid System Components
This vehicle may be equipped with optional High Intensity Discharge (HID) low beams. The HID type lamp is used in place of the conventional halogen
low beam lamp. High beam lamps remain the same halogen type.
HID lamps get their name from the intense white light produced by the electrical discharge. The light produced by the HID lamps appears as a white
color as opposed to the yellow color of the standard halogen lamps.
HID lighting provides about three times the light output of standard halogen lamps while using less energy. The lamps are also designed to last 10 times
longer than standard halogen lamps.
To turn on the headlamps, turn the left end of the Multi-Function Lever to the first detent for parking lamp and instrument panel lamp operation. Turn to
the second detent for headlamp, park lamp and instrument panel lamp operation.
High Intensity Discharge Headlamps (HID) rely on an AC (alternating current) electrical charge to ignite xenon gas contained in a sealed beam lamp.
The HID lamps are similar in operation to common vapor filled street headlamps. Instead of using a filament to produce light, the gas inside the lamp is
ignited by creating an arc between two electrodes.
The color of the light source is classified as its color temperature. As the color temperature increases, the color of the light moves from yellow to
blue-white to white. The light produced by the HID lamps appears as a white color as opposed to the yellow color of the standard (halogen) lamps. HID
lamps provide light as a higher color temperature than standard halogen lamps.
Color Temperature
For the color temperature of different lamp types, refer to the COLOR TEMPERATURE table. As a point of reference, typical sunlight at noon has a
color temperature of 4977° C (8990° F).
There are three components to each of the HID headlamps:
