Handle a halogen headlamp bulb carefully
and keep out of children’s reach. Grasp the
bulb only by its plastic base and do not touch the
glass. The oil from your hand could cause the bulb
to break the next time the headlamps are
operated.

facing upward, insert the glass end of the bulb into
the lamp assembly. You may need to turn the bulb
left or right to align the grooves in the plastic base
with the tabs in the lamp assembly. When the
grooves are aligned, push the bulb into the lamp
assembly until the plastic base contacts the rear of
the lamp assembly.
2. Install the bulb retaining ring over the plastic base
until it contacts the rear of the socket by rotating
clockwise until you feel a“stop.”
3. Connect the electrical connector into the plastic
base until it snaps, locking it into position.
4. Install the headlamp on vehicle by aligning the
lamp with the rear snap retainers, push to seat and
secure with two retainer pins.
5. Turn the headlamps on and make sure they work
properly. If the headlamp was correctly aligned
before you changed the bulb, you should not need to
align it again.
