Headlamp: Testing and Inspection

CHECK-POINTS UPON HEAD LAMP FAILURE
1. Check the battery voltage. (Low beam will be on when the battery voltage above 9 V.)
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 15, replace the ballast and the ignitor (ballast assembly).

Service Procedure And Warning:

Service Procedure And Warning

WARNING
1. HID lamp shall not be used on other cars.(Fire may occur.)
2. Fire may occur when HID lamp initially lights due to the fact that arc-discharge generates high voltage (max. 20,000 V) and high current (12-13 A), and are different from the halogen lamp specification.
3. Install the dust cover after confirming the locking state between bulb and bulb holder.
4. When testing the HID head lamp, turn the power on or off with switch between power supply and lamp because of high voltage.
5. Do not operate the head lamp switch with the bulb not installed, because it generates spark momently
