LIGHTING SYSTEM PRECAUTION

PRECAUTION FOR HID HEADLIGHT SYSTEM

1. When any defects such as deformation, cracks, dents, chipping, etc. are identified on the High Intensity Discharge (HID) headlight (especially, on the light control ECU), replace it with a new one.

2. Even if the operation of the lights seems to be normal, the fail-safe function may be defective.

3. Since an HID headlight bulb has 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.

4. When the HID headlights illuminate, a high voltage (approximately 20000 V) is applied momentarily to the bulb sockets. Never connect a tester to the high voltage socket of an HID headlight for measurement, as this may result in a serious accident because of high voltage.

5. When servicing an HID headlight, do not allow the HID headlight to come into contact with water. 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 shocks.

6. When performing an operation related to an HID headlight, only operate it after assembly is complete. Never turn on the HID headlights without a bulb installed.

7. Do not turn on the HID headlights using a power source other than the vehicle battery.

8. The light color emitted by the HID headlight bulb varies across the ages.

PRECAUTION FOR HEADLIGHT BULB REPLACEMENT

1. If even a thin film of oil is left on the surface of an HID headlight bulb or a halogen bulb, its service life will be shortened because the light will burn at a higher temperature. When replacing a bulb, be sure to hold the flanged part of the light so that your hand does not contact the glass part of the bulb.

2. Due to the high internal pressure of HID headlight bulbs, they may explode and shatter if dropped, hit or damaged.

3. Always prepare a new bulb for immediate replacement. While replacing the bulb, the lens may attract dust and moisture if removed from the vehicle for a long time.

4. Always replace a bulb with another bulb of the same wattage.

5. If only replacing the bulb on one side, differences in brightness and lighting color between the right and left sides may occur.

6. Securely install the socket after bulb replacement. The lens may become cloudy or the light cavity may be filled with water through gaps around the socket if it is not installed securely.

7. Do not break the HID headlight bulb when disposing of it as shards of glass may fly off and cause injuries.

8. It is not possible to determine if an HID headlight bulb is defective by checking it visually. Check the bulb by replacing it with a known good one.
