Left headlamp (663FL)
Right headlamp (663FR)
The headlamp is comprised of the following components:
The task of the headlamps is to provide main beam, dipped beam, parking lights and direction indicators to the front of the car and to regulate beam length with a stepper motor.
The headlamp housing contains bulbs for direction indicator, dipped beam, main beam, and parking light as well as a stepper motor for headlamp levelling. The light sources are protected by one clear plastic lens.
There is a screen in front of the dipped beam bulb, the position of which can be adjusted with a knob to change the dipped beam light image between right-hand and left-hand traffic.
The direction indicator is located out along the long side of the car. It consists of a 21 W amber-coloured bulb and a reflector.
A projector headlamp is located in the centre. It has a light opening diameter of 70 mm. The projector headlamp is used for dipped beam. The bulb is type H7 55 W.
An additional headlamp located closest to the centre of the car is used for main beam and main beam flash. The bulb is type H7 55 W. The parking light bulb is also situated in this headlamp.
A small electric motor with corresponding electronics for manual headlamp levelling is integrated in each headlamp.
