1.PRECAUTION OF HEADLIGHT BULB REPLACEMENT
When any defect such as deformation, cracks, dents, chipping, etc. is identified on the discharge headlight (especially, on the light control ECU), replace it with a new one.
Even if the operation seems to be normal, the fail-safe function may be defective.
Since bulbs of the discharge headlight and halogen bulbs (for headlight and fog light) have pressurized gas inside and can easily be broken if scratched or dropped, special care should be taken. When handling the bulb, hold the plastic or metal part and do not touch the glass part with bare hands.
Never touch the high voltage socket of the discharge headlight with the headlight dimmer switch ON, as this could generate 20,000 V and lead to a serious accident.
Never connect a tester to the high voltage socket of the discharge headlight for measurement, as this may lead to a serious accident because of high voltage.
When performing operations related to the discharge headlight, keep it away from water such as rain, turn off the light control switch, and disconnect the cable from the negative (-) battery terminal and the connector of the light control ECU in advance to avoid electric shock.
When performing operations related to the discharge headlight, operate it after assembling has been finished and never operate it without a bulb installed.
Only illuminate the discharge headlight using the vehicle's power source.
