HEADLAMP
DESCRIPTION
Headlamps on the Ram Pick-Up are modular in
design. The turn/park lamp module is incorporated
into the headlamp module. The module contains two
bulbs; a dual filament headlamp bulb, and a dual fil-
ament turn/park bulb. The Sport headlamp module
has two separate bulbs for the headlamp illumina-
tion.
OPERATION
Headlamps and parking lamps are controlled by
the headlamp switch. The multifunction switch
mounted on the steering column controls the high
beam function, and the turn signal function.

DIAGNOSIS AND TESTING - HEADLAMP
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.
Always begin any diagnosis by testing all of the
fuses and circuit breakers in the system. For com-plete circuit diagrams, refer to the appropriate wir-
ing information. The wiring information includes
wiring diagrams, proper wire and connector repair
procedures, details of wire harness routing and
retention, connector pin-out information and location
views for the various wire harness connectors, splices
and grounds.

ADJUSTMENTS
LAMP ALIGNMENT SCREEN PREPARATION
(1) Position vehicle on a level surface perpendicu-
lar to a flat wall 7.62 meters (25 ft) away from front
of headlamp lens (Fig. 20).(2) If necessary, tape a line on the floor 7.62
meters (25 ft) away from and parallel to the wall.
(3) Up 1.27 meters (5 feet) from the floor, tape a
line on the wall at the centerline of the vehicle. Sight
along the centerline of the vehicle (from rear of vehi-
cle 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 head-
lamp 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.

VEHICLE PREPARATION FOR HEADLAMP
ALIGNMENT
(1) Verify headlamp dimmer switch and high beam
indicator operation.
(2) Verify headlamps are set for low beam opera-
tion.
(3) Correct defective components that could hinder
proper headlamp alignment.
(4) Verify proper tire inflation.
(5) Clean headlamp lenses.
(6) Verify that luggage area is not heavily loaded.
(7) 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.
HEADLAMP ADJUSTMENT
Headlamps can be aligned using the screen method
provided or alignment tool C-4466±A or equivalent
can be used. refer to the instructions provided with
the tool for proper procedures.
A properly aimed low beam headlamp will project
top edge of high intensity pattern on screen from 50
mm (2 in.) above to 50 mm (2 in.) below headlamp
centerline. The side-to-side outboard edge of high
intensity pattern should be from 50 mm (2 in.) left to
50 mm (2 in.) right of headlamp centerline. (Fig. 20)
The preferred headlamp alignment is 1º down
for the up/down adjustment and 0 for the left/
right adjustment.The high beam pattern should be
correct when the low beams are aligned properly.
To adjust headlamp aim, rotate alignment screws
(Fig. 21) to achieve the specified high intensity pat-
tern.

TAIL LAMP
DESCRIPTION
There are two types of tail lamp modules used on
the Ram Truck. One type is integrated into the
pick-up bed, The other is a bracket mounted module
used on the Ram Truck Cab and Chassis. The Cab
and Chassis module is made up of a housing, lens,
and two bulbs. This type of module has license plate
illumination built into the lens. The integrated pick
up module contains a housing, lens, and two bulbs. A
dual filament bulb is used for tail, stop, and turn sig-
nal operations. A separate bulb is used for back-up
illumination.
OPERATION
Tail lamp functions are controlled by the headlamp
switch. Turn signal operations are controlled by the
multifunction switch. Stop lamp functions are con-
trolled by the stoplamp switch. The back-up lamps
are controlled by the back-up lamp switch on the
transmission.
REMOVAL
CHASSIS CAB
