LIGHTING
HEADLIGHTS
General
The headlights are built into the front sheet. The left and
right headlight inserts are identical and freely interchangeable. The headlight bulbs have two filaments for high and
low beam respectively; the beam elevation is controlled
by the combined headlight dimmer/flasher and direction
indicator control lever on the steering column. A light on
the instrument panel glows blue when the headlights are
on at high beam. The standard version is fitted with asymmetric headlights with the beam canted to the right; export models destined for certain markets have asymmetric
lights canted to the left or sealed beam headlights.
As from model 1976, the distribution of light from the
headlights has been improved. For this improvement to
be fully realised additional care must be taken in adjusting
the headlight beams.
As from chassis Nos. 99752023575 and 99756007714,
the headlights on cars for the Swedish market have an
additional function, namely, town lights.
As from chassis nos. 99752023575 and 99756007714
respectively the day-lights are integrated into the headlight unit in the form of a reduced dipped beam. On the
1978-1979 models the day:light is part of the combination light unit. The town lights are designed to make the
car more readily visible during the day when visibility conditions are generally poor as during rain, fog, at twilight,
when there are bright oncoming lights, during snow, etc.
The town lights should not be used for driving at night
when there is no adequate street lighting.
To safeguard against the driver forgetting to switch the
headlights to full power, the headlights are connected in
such a way that high beam can only be obtained with
the headlight switch on.
For details of their functioning refer to section 364 .

Changing headlight inserts
1. Open the hood and pull off the bulb connector.
2. Close the hood without locking it.
3. Remove the grille (see Group 8).
4. Undo the four headlight retaining screws and lift out
the headlight complete with mounting frame.
5. Slacken the adjusting screws until they can be freed
from the retainer lugs on the insert, and then separate
the insert from the retainer plate.
Install in the reverse order.
CHANGING A HEADLIGHT
NOTE
The headlight beam alignment must always be
checked after a headlight insert or bulb has been
exchanged.
BULB, HALOGEN TYPE
NOTE
If the bulb is wrongly oriented in the reflector, the
throw of the beam will be wrong.
Aligning right and left asymmetric beams
Headlight beams are normally adjusted with the help of
special apparatus, but can also be made against a marked
panel or a wall.
REMOVING THE HEADLIGHT
Changing headlight bulbs
The halogen bulbs have almost unchanged light output
during the whole time of burning.
It is also essential that the reflectors are undamaged and
that the wiring terminals make proper contact.
1. Open the hood and remove the contact housing and
rubber sealing cap from the h~adlight.
2. Push in the bulb retainer and twist it counter-clockwise; the bulb can then be withdrawn.
3. Fit the new bulb. Do not touch the glass with your
fingers. Note the three guide lugs and make sure that
the bulb comes in its proper position.
4. Fit the bulb retainer. Make sure that the spring locates
the bulb securely in its correct·position.
5. Push on the connector. Fold down the edge of the
sealing cap, making sure that it fits snugly round the
bulb retainer and that-the drair:i_hole is at the bottom.

Adjustment with beam aligning apparatus
1. Check the tire pressures and load the car as it would
normally be loaded and place the car at right angles
to the apparatus.
Set the lens of the apparatus to the correct height relative to the headlight and to the correct lateral position relative to the asymmetrical part of the headlight
glass.
CAUTION
If the lateral position is set incorrectly this can completely prejudice the alignment work.
a. When the apparatus is suspended from above:
Place the left hand wheels of the car along the line.
A maximum deviation of 1.2 in. (3 cm) in the distance of the front and rear wheels from the line is
permitted.
b. When the beam aligning apparatus is equipped with
an aperture:
Place the apparatus in front of one of the headligh1s,
switch on the beam light and turn the apparatus until the beam strikes the same point on the front
fenders (measured frpm the front edge).
2. Switch on the headlight at low beam.
a. Adjust the height relative to the left-hand (left
asymmetric light: the right-hand) horizontal line.
Adjust the vertical alignment using as reference the
light-dark border which is between 0 and 1.18 in.
(0 and 30 mm) to the left (to the right for left

b. Adjust the lateral setting of the headlight in such a
way that the zone with the highest intensity of
light (A, see illustration) comes as near the centre
as possible. The tolerance band (B) for the lightdark border can be used to obtain the optimum
setting.

Adjustment against panel or wall
1. Check the tire pressures and place the car, loaded in
the same way as ·normally, on a flat surface and at a
distance of 16 ft. 6 in. (5 m) from the panel.
2. Mark the height of the headlight center above the
ground on the panel.
3. Switch on the headlights with the beam dimmed and
mask one Iight.
4. Check and adjust the beam so that the horizontal part
of the dividing line between light and darkness lies
2.0" (50 mm) below the measured dead center of the
headlight and to the left of the center (or to the right
in the case of a left asymmetric beam) - see illustrations. The sloping part of the light-dark dividing line
should lie fully to the right of the mark (to the left
for a left asymmetric beam) and s'iould thus meet the
horizontal part immediately below the dead center.
5. Check the beam of the other light in the same way.
6. Check that the high beam has an even spread. If the
light pattern is irregular or if any difficulty is experi'enced in setting the dimmed beam correctly, check
that the bulb is properly mounted or, if necessary, fit
a new bulb.

PARKING, BRAKING, BACK-UP, DIRECTION INDICATOR AND NUMBER PLATE LIGHTS
General
The front parking lights are recessed in the front fenders
and are combined with the direction indicator lights. As
from model 1977 two new functions are included in the
housings. The upper part holds the direction indicators.
The lower part of the front light contains parking light
and cornering light in the same lampholder by means of a
two-wire lamp. The lower part of the rear lights holds
the side reversing light on the Saab 99 GLE and 99 EMS.
In the rear lights, lamps for rear light, number plate light,
brake light, back-up-light and direction indicators are
mounted.
The brake light switch is mechanical and actuated by the
twist rod between the brake pedal link and the servo assist.
