The headlamps form a unit with the front turn signal lamps and the side lamps. They are made entirely of plastic and can only be replaced as a whole unit.
The motors for the electric headlamp leveling system are integrated in the headlamp unit.
The reflectors are free shape reflectors. The free shape technology allows the full reflector to be utilized.
In this technology, every point of the freely calculated reflector is allocated to illuminating a certain part of the road in front of the vehicle. As a result it is possible to optimize the light distribution through the form of the reflector alone.
The plastic cover is only there for protection.
Conventional H4 bulbs are used in the main headlamps.
The turn signal lamps are yellow and have a special base in order to prevent any confusion.
Glass base bulbs are used for the side lamps.

The turn signal lamps are integrated in the headlamps and have their own reflector with a yellow plastic cover. Colorless bulbs are used.
Glass base bulbs are used for the side lamps.
The headlamp must be removed in order to replace the bulbs.
Front fog lamps
As well as the rear lamps, the rear lamp clusters incorporate all rearward facing lights with exception of the license plate lamp and the additional high-mounted stoplamp.
The rear lamps can only be replaced as a complete unit.
They incorporate a bulb carrier with the bulb sockets.
The bulb carrier is connected to the wiring harness via a compact connector.
The rear lamp cluster should be detached from the vehicle before replacing any bulbs.
Side lamp
The side lamp is a combined bulb which also includes the stoplamp.
Stoplamp
The additional high-mounted stoplamp is mounted in the middle of the tailgate above the rear window and also incorporates the washer nozzle for the rear window. A glass base bulb is used.
The stoplamps are switched on via the stoplamp switch on the brake pedal as soon as the brake pedal is actuated.
Turn signal lamps
The turn signal lamps serve as direction indicators and for the hazard warning lights. A yellow bulb is used.
The function of the turn signal lamps is controlled by the GEM, as a result of which the conventional turn signal/hazard warning relay is no longer required.
The sound generator for the acoustic turn signal check is integrated in the multifunction switch.
Reversing lamp
The reversing lamp serves to illuminate the road when reversing and is switched on by the reversing lamp switch when reverse gear is engaged.
There is only a reversing lamp on the passenger side of the vehicle, i.e. on the right-hand side for a LHD vehicle and on the left-hand side for a RHD vehicle.
Rear fog lamp
The rear fog lamp serves for greater visibility of the vehicle from behind for following road users and can only be switched on when at least the side lamps are switched on.
This is achieved via the mechanical design of the light switch, which will only allow the lever to be pulled if it was moved to at least "P" beforehand.
The rear fog lamp is always installed on the driver's side, i.e. on the opposite side to the reversing lamp
Rear lighting - Fiesta built from 08/2005
The rear lamps can only be replaced as a complete unit.
They contain individual holders for the bulbs.
The holders are connected to the wiring harnesses via individual connectors.
The rear lamp cluster should be detached from the vehicle before replacing any bulbs.
Autolamps - vehicles built from 08/2005
The combined rain sensor/light sensor is attached to the windshield, near to the interior rear view mirror.
The ambient light sensor determines the general light intensity. For this purpose, it records the light over as wide an angle as possible, without taking the direction of incidence into account.
The front light sensor determines the light intensity directly in front of the vehicle.
If both the ambient light sensor and the front light sensor detect a sudden reduction in light intensity at the same time, then an algorithm-based calculation is used to determine the fact that the vehicle has entered a tunnel.
In this case the request for switching on the external lighting and the indicator lamp in the instrument cluster is transmitted to the GEM.
If the sun is shining and the vehicle is suddenly thrown into the shade by a large truck, the two sensors will register different light intensities. In this case, the algorithm-based calculation will not result in the lights being switched on.
