Each vehicle is equipped with various lamp assemblies. A good ground is necessary for proper lighting
operation. Grounding is provided by the lamp socket
when it comes in contact with the metal body, or
through a separate ground wire.
When changing lamp bulbs check the socket for
corrosion. If corrosion is present, clean it with a wire
brush and coat the inside of the socket lightly with
Mopar Multi-Purpose Grease or equivalent.
SAFETY PRECAUTIONS
WARNING: EYE PROTECTION SHOULD BE USED
WHEN SERVICING GLASS COMPONENTS. PERSONAL INJURY CAN RESULT.

When it is necessary to remove components to service another, it should not be necessary to apply
excessive force or bend a component to remove it.
Before damaging a trim component, verify hidden
fasteners or captured edges are not holding the component in place.
DAYTIME RUNNING LAMP MODULE
PL vehicles built for use in Canada are equipped
with a Daytime Running Lamp (DRL) system. The
DRL system operates the headlamps at 50% illumination with the headlamp switch OFF, park brake
released and the ignition ON. The DRL system is
controlled by the Daytime Running Lamp Module.
The DRL module overrides the headlamp switch
when the headlamps are turned OFF. The headlamps
operate normally when the headlamps are turned
ON.
CAUTION: Do not touch the glass of halogen bulbs
with fingers or other possibly oily surface, reduced
bulb life will result.
Do not use bulbs with higher candle power than
indicated in the Bulb Application table at the end of
this group. Damage to lamp can result.
Do not use fuses, circuit breakers or relays having greater amperage value than indicated on the
fuse panel or in the Owners Manual.
DIAGNOSIS AND TESTING
DIAGNOSTIC PROCEDURES
When a vehicle experiences problems with the
headlamp system, verify the condition of the battery
connections, charging system, headlamp bulbs, wire
connectors, relay, high beam dimmer switch and
headlamp switch. Refer to Group 8W, Wiring Diagrams for component locations and circuit information.

DIAGNOSIS AND TESTING (Continued)
HEADLAMP DIAGNOSIS
Always begin any diagnosis by testing all of the
fuses and circuit breakers in the system. Refer to
Group 8W, Wiring Diagrams.
Conventional and halogen headlamps are interchangeable. It is recommended that they not be
intermixed on a given vehicle.

GENERAL INFORMATION
HEADLAMP ALIGNMENT
Headlamps can be aligned using the screen method
provided in this section. Alignment Tool C4466-A or
equivalent can also be used. Refer to instructions
provided with the tool for proper procedures. The
preferred headlamp alignment setting is 0 for
the left/right adjustment and 0 for the up/down
adjustment.
SERVICE PROCEDURES
HEADLAMP ALIGNMENT PREPARATION
(1) Verify headlamp dimmer switch and high beam
indicator operation.
(2) Inspect and correct damaged or defective components that could interfere with proper headlamp
alignment.
(3) Verify proper tire inflation.
(4) Clean headlamp lenses.
(5) Verify that luggage area is not heavily loaded.
(6) Fuel tank should be FULL. Add 2.94 kg (6.5
lbs.) of weight over the fuel tank for each estimated
gallon of missing fuel.
ADJUSTMENTS
HEADLAMP ADJUSTMENT USING ALIGNMENT
SCREEN
ALIGNMENT SCREEN PREPARATION
(1) Position vehicle on a level surface perpendicular to a flat wall 7.62 meters (25 ft) away from front
of headlamp lens (Fig. 1).
(2) If necessary, tape a line on the floor 7.62
meters (25 ft) away from and parallel to the wall.
(3) From the floor up 1.27 meters (5 ft), tape a line
on the wall at the centerline of the vehicle. Sight
along the centerline of the vehicle (from rear of vehicle forward) to verify accuracy of the line placement.

(4) Rock vehicle side-to-side three times to allow
suspension to stabilize.
(5) Jounce front suspension three times by pushing
downward on front bumper and releasing.
(6) Measure the distance from the center of headlamp lens to the floor. Transfer measurement to the
alignment screen (with tape). Use this line for
up/down adjustment reference.
(7) Measure distance from the centerline of the
vehicle to the center of each headlamp being aligned.
Transfer measurements to screen (with tape) to each
side of vehicle centerline. Use these lines for left/
right adjustment reference.
HEADLAMP ADJUSTMENT
A properly aimed low beam headlamp will project
the top edge of low beam hot spot on the alignment
screen from 50 mm (2 in.) above to 50 mm (2 in.)
below the headlamp centerline. The side- to-side left
edge of low beam hot spot should be from 50 mm (2
in.) left to 50mm (2 in.) right of headlamp centerline
(Fig. 1). The preferred headlamp alignment is 0
for the up/down adjustment and 0 for the left/
right adjustment. The high beams on a vehicle
with aero headlamps cannot be aligned. The high
beam pattern should be correct when the low beams
are aligned properly.
To adjust headlamp alignment, rotate alignment
screws to achieve the specified low beam hot spot
pattern.
FOG LAMP ALIGNMENT
Prepare an alignment screen. Refer to Alignment
Screen Preparation paragraph in this section. Disengage the wire connectors from the back of the headlamp bulbs to disable the headlamps. This will allow
a more accurate projection reading of the fog lamps.
Turn on the headlamp switch and actuate the fog
lamp switch. A properly aligned fog lamp will project
a pattern on the alignment screen 100 mm (4 in.)
below the fog lamp centerline and straight ahead
(Fig. 2).
