OVERVIEW
Three levels of exterior lighting are available depending on vehicle specification:
Halogen headlamps
Bi-xenon High Intensity Discharge (HID) headlamps
Bi-xenon HID Adaptive Front lighting System (AFS) headlamps.
A light switch module is located in the instrument panel and allows the driver to select the appropriate operation of the
exterior lighting systems.
The rear lamp assemblies contain side lamps, stop lamps, reverse lamps, turn signal indicators and rear fog lamps. On
North American Specification (NAS) vehicles the rear lamp assembly also includes a side marker lamp. The rear lamp
assemblies require removal for bulb replacement. Two reflectors are mounted in the rear bumper.
All versions of the headlamps have impact resistant polycarbonate lens'. Removable covers at the rear of the headlamps
allow for bulb replacement. The headlamps require removal for bulb replacement.
The halogen headlamps have large complex surface reflectors to optimise the beam patterns in low beam only. A high
beam only reflector is located on the inboard side of the headlamp. Headlamp leveling on the halogen headlamps is
manually adjusted using a rotary thumbwheel located in the light switch module which operates leveling motors located in
the headlamp.
The bi-function HID headlamps and the AFS headlamps use a projector unit with a D1S xenon bulb which operates in both
low and high beam. An additional halogen high beam only reflector is located on the inboard side of the headlamp.
Headlamp leveling is automatic on the HID headlamps. Front and rear height sensors are located on the Left Hand (LH)
side of the front and rear axles. These measure the vehicle attitude and a headlamp leveling module, which is located on
the bulkhead 'A' pillar behind the glovebox, automatically controls the headlamp vertical alignment.
Headlamp powerwash is a standard fitment on HID headlamps.
Turn signal indicators and high and low beam functions are controlled from the LH steering column multifunction switch.
The turn signal indicators have a lane change feature. A single press and release of the multifunction switch in either
direction will operate the selected turn signal indicators for 3 cycles.
The exterior lighting is controlled by the CJB. The CJB is the main controlling module for vehicle body systems and is
located behind the glovebox in the instrument panel.
The CJB provides circuit protection for all exterior lighting circuits.

CENTRAL JUNCTION BOX (CJB)
The CJB receives exterior lighting related inputs from the following switches:
Light switch module
- Side lamp position
- Headlamp position
- Automatic (AUTO) position (if fitted)
- Front fog lamp switch (if fitted)
- Rear fog lamp switch
- Dimmer control
- Headlamp leveling control (if fitted).
Brake switch
LH steering column multifunction switch for turn signal indicators and high beam/headlamp flash
Hazard flasher switch
Rain/light sensor (LIN signal).
Circuit Protection
Two 60 Amp fusible links in the battery junction box protect the power feed to the CJB LH and RH lighting circuits
respectively. All exterior lighting circuits are protected by Field Effect Transistors (FETs), located in the CJB, which can
detect overloads and short circuits.
The FETs respond to heat generated by increased current flow caused by a short circuit. On a normal circuit this would
cause the fuse to blow. The FETs respond to the heat increase and disconnect the supply to the affected circuit. When the
fault is rectified or the FET has cooled, the FET will reset and operate the circuit normally. If the fault persists the FET will
cycle, disconnecting and reconnecting the power supply. The CJB stores fault codes which can be retrieved using a Land
Rover approved diagnostic system. The fault code will identify that there is a fault on a particular output which assist in
fault detection.
Alarm Indications
The exterior lighting system is used for alarm arm and disarm requests. When the driver locks or unlocks the vehicle, a
visual indication of a successful lock or unlock request is displayed to the driver by the hazard flashers operating a number
of times.
For additional information, refer to:
Anti-Theft - Active
(419-01A Anti-Theft - Active, Description and Operation).
Lights On Warning chime
When the ignition in the off (power mode 0) or auxiliary (power mode 4) mode and the lighting control rotary switch is in
the side lamp or headlamp position, a warning chime will sound if the driver's door is opened. This indicates to the driver
that the exterior lights have been left on. The chime is generated from the instrument cluster sounder on receipt of a
lights on signal, a door open signal and an ignition switch off signal from the CJB on the high speed CAN bus.
Crash Signal Activation
When a crash signal is transmitted from the Restraints Control Module (RCM), the CJB activates the hazard flashers and
the turn signal indicators in the instrument cluster. The hazard flashers will continue to operate until the ignition mode is
changed to the auxiliary power mode 4or the off power mode 0 or the RCM no longer transmits the crash signal.
For additional information, refer to:
Air Bag and Safety Belt Pretensioner Supplemental Restraint System (SRS)
(501-20B
Supplemental Restraint System, Description and Operation).
Headlamp Timer
The CJB controls a headlamp timer function which allows the headlamps to remain on for a period of time after leaving the
vehicle. This is a driver convenience feature which illuminates the driveway after leaving the vehicle.
This feature can only be activated by pulling the high beam ' flash-to-pass' on the LH steering column multifunction switch.
It can be deactivated either by timing out or by pulling the multifunction switch again.
The default setting can be changed by a Land Rover or authorized dealer . The default timing is set to 30s but can be
changed to 0s (OFF), 30s (default), 60s, 90s, 120s, 150s and 180s.

Interior illumination dimmer rotary control
The light switch module is located in the driver's side of the instrument panel and allows the driver to control the
operation of the exterior lighting system. Three variants of the module are available to cover different vehicle
specifications and market variants.
All switch operations are detected by the light switch module and sent as Local Interconnect Network (LIN) messages to
the CJB.
Lighting Control Rotary Switch
The light control module has a central rotary switch which allows the following selections:
All exterior lamps off
Side lamps on
Headlamps on
Automatic headlamps active.
Headlamp Leveling (ROW halogen headlamps only)
• NOTE: Headlamp levelling is not available on NAS vehicles with halogen headlamps.
A rotary leveling thumbwheel is located on the RH side of the light switch module. The rotary thumbwheel is connected to
a rheostat which gives a variable output to the headlamp leveling stepper motors. The motors respond to the output and
move to adjust the headlamp vertical alignment as required.
The control has no defined positions but can be adjusted as required to compensate for a drop in height at the rear of the
vehicle and avoid dazzle to oncoming drivers.
Dimmer Control
A rotary dimmer thumbwheel is located on the LH side of the light switch module. The dimmer control provides a Pulse
Width Modulated (PWM) output to control the illumination brightness of the instrument panel and other instrument panel
illumination.
The dimmer switch operates using a rotary thumbwheel which is connected to a rheostat and a high side switch. The
rheostat is a variable resistor which provides a high or low resistance according to its set position. This output is passed
to a switchable capacitor or a high side switch. The high side switch uses the output from the rheostat to determine the
switching frequency of the capacitor which provides the PW M output of between 8 and 12V to determine the brightness of
the illumination.
Fog Lamps
Two switches are provided for selection of the front and rear fog lamps. The front fog lamp switch is only fitted to vehicles
with front fog lamps.
The fog lamp switches are momentary switches, which when pressed, generate a LIN bus message from the light switch
module to the CJB. The fog lamps remain active until deselected using the applicable fog lamp switch or the headlamps
are switched off or the ignition power mode 6 is changed to the off power mode 0.
Automatic Headlamps
The automatic headlamp function is a driver assistance system. The driver can override the system operation by selection
of side lamp or headlamp on if the ambient light conditions require front and rear lighting to be active.
