Kia Forte: Head Lamps 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).
|
|
|

|
Replacement of lamp assembly
|
|
1. |
Disconnect the power connector from the lamp.
|
|
2. |
Remove and replace the lamp assembly.
|
|
3. |
Connect the power connector.
|
|
|
• |
Disconnect the head lamp power connector to avoid
high voltage.
|
|
|
• |
Other description is the same as the halogen bulbs.
|
|
2
|
Replacement of the Bulb
|
|
1. |
Disconnect the power connector from the lamp.
(head lamp, turn signal, head lamp leveling device)
|
|
2. |
Remove the lamp assembly.
|
|
3. |
Remove the ballast and dust cover.
|
|
4. |
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.
|
|
• |
Do not apply excessive force and fit it correctly.
|
|
|
3
|
Replacement of the Ballast (with built-in ignitor)
|
|
1. |
Disconnect the power connector from the lamp.
|
|
2. |
Remove the lamp and then the ballast and the dust
cover.
|
|
3. |
Remove the head lamp leveling device and then
the bulb socket.
|
|
4. |
Connect the bulb socket on the replacement ballast
and install the leveling device.
|
|
5. |
Installation is the reverse of removal.
|
|
|
• |
Disconnect the head lamp power connector to avoid
high voltage.
|
|
|
• |
Replace the ballast only and install the used
lamp.
|
|
• |
Replace the sub assembly except the ballast.
|

|
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. |
Operating input voltage : 9-16V
