Using the right bulbs
Replacement bulbs are specified in the chart below. Headlamp bulbs
must be marked with an authorized “D.O.T.” for North America and an
“E” for Europe to ensure lamp performance, light brightness and pattern
and safe visibility. The correct bulbs will not damage the lamp assembly
or void the lamp assembly warranty and will provide quality bulb burn
time.

Replacing front parking/cornering/turn signal lamp bulbs
To remove the parking/cornering/turn signal lamp bulbs:
1. Make sure the headlamp switch is in the off position, then open the
hood.
2. Remove the three pin type retainers and the radiator shield.
3. Remove two nuts from the back
side of the lamp assembly, then pull
the lamp assembly away from the
vehicle.
4. Rotate the bulb socket
counterclockwise and remove it
from the lamp assembly.
5. Carefully pull bulb straight out of
the socket and push in the new
bulb.
6. To install, reverse the order of
the removal procedure.
Note:The parking lamp/turn signal bulbs should not be removed from
the lamp until just before a replacement bulb is installed. Removing the
bulb for an extended period of time may affect headlamp bulb
performance. Contaminants may enter the headlamp where they can
settle on the lens and reflector. Never turn the lamps on with the bulb
removed.
Replacing tail lamp/brake/turn lamp bulbs
The tail lamp, the brake lamp and the turn signal lamp bulbs are located
in the tail lamp assembly. Follow the same steps to replace either bulb.
