A transient high tension (25,000 V) occurs at the
bulb sockets of the high intensity discharge (HID)
lamps when the combination light switch is turned
ON. It may cause serious electrical shock or
electrocution if you do not observe the cautions.
 Never turn on the combination light switch before fitting the HID bulbs to their bulb sockets
and completing the reassembly of the headlight
assembly.
 Do not service the headlight assembly in wet conditions, such as rain or snow, near a sprinkler
system, or when your hands are wet to prevent
electrocution.
 Do not touch the surface of the HID bulbs with your bare hands and do not stain it with any oils
and fats.
 Do not disassemble the inverter unit and the igniter fats.
 Do not turn on the HID bulb by using a power source other than the battery mounted on your
vehicle.
1. Turn the combination light switch OFF.
2. Do the battery terminal disconnection procedure (see page 22-68).
3. Remove the battery. (left side bulb) 4. Turn the cover (A) 45 ° counterclockwise to remove
it from the headlight assembly.
5. Turn the socket (A) 45 ° counterclockwise to remove it from the bulb (B).
6. Pull the retaining spring (C) away from the bulb then remove the bulb.
7. Install the new bulb in the reverse order of removal. Make sure the notches in the bulb align with the
tabs in the headlight.
8. Install the parts in the reverse order of removal.
9. Do the battery terminal reconnection procedure (see page 22-68).
