NOTE:On vehicles equipped with High Intensity Dis-
charge Headlights (HID), when the headlights are turned
on there is a blue hue to the lights. This diminishes and
becomes more white after approximately 10 seconds, as
the system charges.
High Intensity Discharge Headlights (HID)
The headlights are a type of high voltage discharge tube.
High voltage can remain in the circuit even with the
headlight switch off and the key removed.Because of
this, you should not attempt to service a headlight bulb
yourself. If a headlight bulb fails, take your vehicle to
an authorized dealer for service.
WARNING!
A transient high tension occurs at the bulb sockets of
High Intensity Discharge (HID) headlights when the
headlight switch is turned ON. It may cause serious
electrical shock or electrocution if not serviced prop-
erly. See your authorized dealer for service.
NOTE:If High Intensity Discharge (HID) lights are not
working, recycle the headlight switch 4 times to see if it
will restrike.

License Plate Light
Twist off sockets counter-clockwise and pull out bulbs.
Replace as required.
Headlight Aiming
The headlights on your new Viper were aimed at the
factory. The factory setting was made at a no load setting.
A great increase in weight will change the aiming and it
may be necessary to readjust the headlights if you
typically carry an excessive amount of weight in the
trunk or otherwise suspect misalignment.

Aiming Check
Each headlight assembly can be adjusted up and down
only. No left to right adjustment is necessary. To check,
proceed as follows:
1. Fill the fuel tank and park the vehicle on level ground.
A driveway is not normally level. If in doubt and you
have no way to check levelness, do not attempt to adjust
the headlights.
2. Mark the position of the headlights on a wall prior to
loading the vehicle. Load the trunk with the items you
normally carry. Have someone sit in the driver's seat who
is about the same weight as the person who drives the
vehicle.3. Push down on the front and rear of the vehicle several
times to make sure that the suspension has settled.
4. Then readjust the headlights to the original position.
NOTE:If any further adjustments are necessary, contact
your dealership.
