Kia Optima: Inspection
| 1. |
Check-points upon head lamp failure
(HID)
| (1) |
Check the battery voltage.
(Low beam will be on when the battery voltage above 9V.) |
| (2) |
Check the fuse and relay. |
| (3) |
Check the polarity of
ballast. (If the polarity are changed, low beam doesn't lighten) |
| (4) |
Check the bulb connector
securely. |
| (5) |
Visually bulb checking
(no filament): damaged glass, damaged for upper parts and lower
parts of glass tube. |
| (6) |
After (1)~(5), replace
the ballast and the ignitor. (ballast assembly).
|
If a headlamp goes out after a period of operation but will
immediately relights when the headlamp switch is cycled
it is likely the HID lamp needs to be replaced. |

|
Replacement of the Bulb
|
| 1. |
Disconnect the
power connector from the lamp. (head lamp, turn signal,

Remove the bulb
socket and replace the bulb. |
| 5. |
Installation
is the reverse of removal. |
|
| •
|
Disconnect the
head lamp power connector to avoid high voltage. |
| •
|
Be careful not
to damage the bulb and use genuine bulbs only. |
| •
|

|
Others
|
| 1. |
Power supply
should be according to the rated capacity. |
| 2. |
Use the rated
fuse and wire. |
| 3. |
Bulb socket shall
be free from moisture or dirt. |
| 4. |
Do not apply
the ballast severe shock, water, or extreme |
|
| •
|
All parts should
be serviced only at specified service centers. |
|
| •
|
HID lamp should
not be installed on other cars (Dangerous, fire may occur.) |
|
|
HID lamp shall not be used on other cars.(Fire may occur.) Fire
may occur when HID lamp initially lights due to the fact that arc-discharge
generates high voltage (max. 30,000V) and high current (12-13A),
and are different from the halogen lamp specification.
|
|
| 3. |
Understanding of color change
by replacement of HID bulb.
| (1) |
The cause of HID color
change. (Change of color is HID feature)
| A. |
The change of
color occur during mixing three Elements in the HID bulb.
|
| B. |
Color Coordinates
by Lifetime
|
| C. |
Chemical compounds
in an arc tube : |
| 1. |
Xenon gas(an
inert gas , protection of arc tube) |
| 2. |
Mercury( increase
voltage, protection of arc tube, blue in the first 3 second
) |
| •
|
Natrium(Yellow)
: 0.12mg |
| •
|
Scandium(Blue)
: 0.06mg |
| •
|
Iodine(Halogen)
: 0.02mg |
|
| (2) |
Change of Color by Lighting
Up Time
| A. |
It needs 4 seconds
at least for stabilization. At first, you can see the
blue for 3 seconds because of Mercury.
|
| B. |
After stabilization,
change of color occur by metal halide. |
| •
|
0 Hour : Yellow(
Na is more than Sc. ) |
| •
|
10 Hour : Bright
Blue (Na and Sc are similar ratio.) |
| •
|
1000Hour more
: Blue ( Sc is more than Na.) |
| C. |
The end of lifetime
: When HID used up Natrium and Scandium, a beam of light
will be dark suddenly. so you can see the red, purple
and turn on and off.

|
Characteristic
| 1. |
Durable for vibration as there
is no filament. |
| 2. |
HID lamp had a more long life
than halogen lamp. |
| 3. |
Does not operate if polarity
is changed. |
| 4. |
