The high intensity discharge
lighting system operates at a very
high voltage. If you try to service
any of the system components,
you could be seriously injured.

technician service them.
The vehicle may have HID
headlamps. After an HID headlamp
bulb has been replaced, you may
notice that the beam is a slightly
different shade than it was originally.
This is normal.

rearward until the inner pins on
the taillamp assembly disengage
from the vehicle.
4. Turn the socket
counterclockwise to remove it
from the taillamp assembly.

from the socket.
