on the approximationof the lawsofthe Member States relating to
the installation of lighting and light-signalling devices on motor
vehiclesandtheirtrailers
(76/756/EEC)
THE COUNCIL OF THE EUROPEAN COMMUNITIES,
Having regard to the Treaty establishing the European Economic
Community, and in particular Article 100 thereof,
Having regard to the proposal from the Commission,
Having regard to the opinion of the European Parliament (1),
Having regard to the opinion of the Economic and Social
Committee (2),
Whereas the technical requirements which motor vehicles must satisfy
pursuant to national laws relate inter alia to the installation of lighting
and light-signalling devices;
Whereas those requirements differ from one Member State to another;
whereas it is therefore necessary that all Member States adopt the samerequirements either in addition to or in place of their existing rules, in
order, in particular, to allow the EEC type-approval proccedure which
was the subject of Council Directive 70/156/EEC of 6 February 1970on the approximation of the laws of the Member States relating to thetype-approval of motor vehicles and their trailers (
3), to be introduced
in respectof each t ype of vehicle;
Whereas common requirements for the construction of lighting and
light-signalling devices will be the subject of further special Directives;
Whereas approximation of the national laws relating to motor vehicles
entails mutual recognition by the Member States of the checks carriedout by each of them on the basis of the common requirements;whereas, if the system is to function properly, these requirementsmust be applied from the same date,
HAS ADOPTED THIS DIRECTIVE:
Article 1
For the purposes of this Directive, ‘vehicle’ means any motor vehicle
intended for use on the road, with or without bodywork, having at least
four wheels and a maximum design speed exceeding 25 kilometres perhours, and its trailers, with the exception of vehicles which run on rails,agricultural or forestry tractors and machinery, and public-works vehi-cles.
Article 2
1. No Member State may:
— refuse, in respect of a type of vehicle, to grant EEC type-approval
or national type-approval, or
— refuse or prohibit the sale, registration, entry into service or use of
vehicles,
on grounds relating to the installation on the vehicles of the lighting
and light-signalling devices, whether mandatory or optional, listed in1976L0756 — EN — 14.12.1983 — 004.001 — 2

provisions of item 4.2.6 of Annex I shall be required only with effect
from 1 October 1984. However, where devices such as those referredto in item 4.2.6.2 are installed before that date, they must satisfy therequirements set out in item 4.2.6. Where EEC type-approval (or theissue of the document referred to in the last indent of Article 10 (1)of Directive 70/156/EEC) or national type-approval was granted after
1 October 1979 and before 1 October 1984 in respect of a vehicle
type that does not comply with the requirements referred to in para-graph 1, Member States may prohibit the first entry into service ofvehicles of that type with effect from 1 October 1987.
Article 3
A Member State which has granted EEC type-approval shall take the
necessary measures to ensure that it is informed of any modificationto any of the parts or characteristics referred to in item 1.1 of Annex
I. The competent authorities of that Member State shall determine
whether further tests should be carried out on the modified vehicletype and a fresh report drawn up. Where such tests reveal failure tocomply with the requirements of this Directive, the modification shallnotbe approved.

‘Concealable illuminating lamp’ means a headlamp capable of
being partly or completely hidden when not in use. This result
may be achieved by means of a movable cover, by displacement
of the headlamp or by any other suitable means. The term
‘retractable’ is used more particularly to describe a concealable
lamp the displacement of which enables it to be inserted within

1.6. Illuminatingsurfaceofalamp
1.6.1. Illuminating surface of a lighting device
‘Illuminating surface of a lighting device’ (1.5.7 to 1.5.10)
means the orthogonal projection of the full aperture of the
reflector in a transverse plane. If the lighting device has no
reflector, the definition of item 1.6.2 shall be applied. If the
lamp glass (or glasses) extend(s) over part only of the full aper-
ture of the reflector, then the projection of that part only is taken
into account.
In the case of a dipped-beam headlamp, the illuminating surface
is limited by the apparent trace of the cut-off on to the lens. If
the reflector and glass are adjustable relative to one another, the
mean adjustment should be used.1976L0756 — EN — 14.12.1983 — 004.001 — 6

▼B
▼M1
▼B
1.6.2. Illuminating surface of a signalling lamp other than a reflex
reflector
‘Illuminating surface of a signalling lamp other than a reflex
reflector’ (1.5.11 to 1.5.19) means the orthogonal projection of
the lamp in a plane perpendicular to its axis of reference and in
contact with the exterior light-emitting surface of the lamp, this
projection being bounded by the edges of screens situated in this
plane, each allowing only 98% of the total luminous intensity of
the light to persist in the direction of the axis of reference. To
determine the lower, upper and lateral limits of the illuminating
surface, only screens with horizontal or vertical edges shall be
used.
1.6.3. Illuminating surface of a reflex reflector
‘Illuminating surface of a reflex reflector’ (1.5.20) means the
illuminating surface of a reflex reflector in a plane perpendicular
to the axis of reference and bounded by planes touching the outer
edges of the light projection surface of the reflex reflector and
parallel to this axis. To determine the lower, upper and lateral
limits of the illuminating surface, only vertical and horizontal
planes shall be used.
1.6.4. Apparent surface
‘Apparent surface’, for a defined direction of observation, means
the orthogonal projection of the light-emitting surface in a plane
perpendicular to the direction of observation (see drawing in
Appendix 2) and tangential to the most exterior point of the lens.
1.6.5. Light-emitting surface
‘Light-emitting surface’ means all or part of the exterior surface
of the translucent material which helps to confer on the light its
particular photometric and colorimetric properties.
When only part of the exterior surface emits light, the light-emit-
ting surface shall, in case of doubt, be specified by the
competent authority after consultation with the vehicle and/or
componentmanufact urer.
1.7. Axisofreference
‘Axis of reference’ means the characteristic axis of the light
signal, determined by the manufacturer for use as the direction
of reference (H = 0º, V = 0º) for photometric measurements and
when fitting the lamp on the vehicle.
1.8. Centreofreference
‘Centre of reference’ means the intersection of the axis of refer-
ence with the light-emitting surface. This centre of reference is
to be specified by the manufacturer of the lamp.
1.9. Anglesofgeometric visibility
‘Angles of geometric visibility’ means the angles which deter-
mine the field of the minimum solid angle in which the
apparent surface of the lamp must be visible. That field of the
solid angle is determined by the segments of the sphere of which
the centre coincides with the centre of reference of the lamp and
the equator is parallel with the ground. These segments are deter-
mined in relation to the axis of reference. The horizontal angles
βcorrespond to the longitude and the vertical angles αto the lati-
tude. There must be no obstacle on the inside of the angles of
geometric visibility to the propagation of light from any part of
the apparent surface of the lamp observed from infinity.
If measurements are taken closer to the lamp, the direction of
observation must be shifted parallel to achieve the same accu-
racy.
On the inside of the angles of geometric visibility no account is
taken of obstacles, if they were already presented when the lamp
was type-approved.1976L0756 — EN — 14.12.1983 — 004.001 — 7
▼M1

▼M1
If, when the lamp is installed, any part of the apparent surface of
the lamp is hidden by any further parts of the vehicle, proof shall
be furnished that the part of the lamp not hidden by obstacles
still conforms to the photometric values prescribed for the
approval of the device as an optical unit (see figure below).
1.10. Extremeouteredge
‘Extreme outer edge’ on either side of the vehicle means the
plane parallel with the median longitudinal plane of the vehicle
and coinciding with its lateral outer edge, disregarding the
projection:
1.10.1. of tyres near their point of contact with the ground, and connec-
tions for tyre-pressure gauges;
1.10.2. of any anti-skid devices which may be mounted on the wheels;
1.10.3. of rear-view mirrors;
1.10.4. of side direction indicator lamps, end-outline marker lamps, front
and rear position (side) lamps, parking lamps and reflex reflec-
tors;
1.10.5. of customs seals affixed to the vehicle, and devices for securing
and protecting such seals.
1.11. Overallwidth
‘Overall width’ means the distance between the two vertical
planes defined in 1.10.
1.12. Asinglelamp
‘A single lamp’ also means any combination of two or more
lamps, whether identical or not, having the same function and
emitting light of the same colour, if it comprises devices, the1976L0756 — EN — 14.12.1983 — 004.001 — 8

▼M1
projection of whose aggregate illuminating surfaces in a given
transverse plane occupies 60 % or more of the area of the smal-
lest rectangle circumscribing the projections of those illuminating
surfaces, provided that such combination is, where approval is
required, approved as a single lamp.
This possible combination does not apply to main-beam head-
lamps, dipped-beam headlamps and frontfog lamps.
1.13. Twolampsoranevennumberoflamps
‘Two lamps’ or ‘an even number of lamps’ means a single
►M1►C1illuminating surface ◄◄ in the shape of a band
if placed symmetrically in relation to the median longitudinal
plane of the vehicle and extending on both sides to within not
less than 400 mm of the extreme outer edge of the vehicle, and
being not less than 800 mm long. The illumination of such a
surface shall be provided by not less than two light sources
placed as close as possible to its ends. The
►M1►C1illuminating surface ◄◄ may be constituted by
a number of juxtaposed elements on condition that the projec-
tions of the several individual ►M1►C1illuminating
surfaces ◄◄ on the same transverse plane occupy not less
than 60% of the area of the smallest rectangle circumscribing
the projections of those individual ►M1►C1illuminating
surfaces ◄◄ .
1.14. Distancebetweentwolamps
‘Distance between two lamps’ which face in the same direction
means the shortest distance between the orthogonal projections in
a plane perpendicular to the axes of reference of the outlines of
the two illuminating surfaces as defined according to the case
mentioned in 1.6. The distance between two lamps may,
however, be measured without determining the outlines of the
illuminating surfaces exactly, where the distance is clearly in
excess of the minimum requirements of the Directive.
1.15. Optionallamp
‘Optional lamp’ means a lamp the presence of which is left of
the discretion of the manufacturer.
1.16. Operationaltell-tale
‘Operational tell-tale’ means a light or auditory device showing
whether a device that has been actuated is operating correctly or
not.

type-approval document.
3. GENERAL SPECIFICATIONS
3.1. The lighting and light-signalling devices must be so fitted that
under normal conditions of use, and notwithstanding any vibra-
tion to which they may be subjected, they retain the
characteristics laid down in this Annex and enable the vehicleto comply with the requirements of this Annex. In particular, it
shall not be possible for the adjustment of the lamps to be inad-
vertently disturbed.
3.2. The illuminating lamps described in 1.5.7, 1.5.8 and 1.5.9 must
be so fitted that a correct setting of their alignment can easily
be performed.
3.3. For all light-signalling devices, including those mounted on the
side panels, the reference axis of the lamp when fitted to the
vehicle must be parallel with the bearing plane of the vehicle
on the road; in addition, it must be perpendicular to the median
longitudinal plane of the vehicle in the case of side reflex reflec-
tors and parallel to that plane in the case of all other signalling
devices. In each direction a tolerance of ±3º shall be allowed. In
addition, any specific instructions as regards fitting laid down by
the manufacturer must be complied with.
3.4. In the absence of specific requirements, the height and alignment
of the lamps shall be checked with the unladen vehicle placed on
a flat, horizontal surface.
3.5. In the absence of specific requirements, lamps constituting a pair
shall:
3.5.1. be fitted to the vehicle symmetrically in relation to the median
longitudinal plane (this estimate to be based on the exterior
geometrical form of the lamp and not on the edge of its illumi-
nating surface referred to in 1.6);
3.5.2. be symmetrical to one another in relation to the median longitu-
dinal plane; this requirement is not valid with regard to the
interior structure of the lamp;
3.5.3. satisfy the same colorimetric characteristics;
3.5.4. have substantially identical photometric characteristics.3.6. On vehicles whose external shape is asymmetrical, the above
requirements shall be satisfied as far as possible.
3.7. Lamps having differentfunct ions may be independentor be
grouped, combined or reciprocally incorporated in one device,
provided that each such lamp complies with the requirements
applicable to it.1976L0756 — EN — 14.12.1983 — 004.001 — 10

3.8. The maximum heightabove ground shall be measured from t he
highest point and the minimum height from the lowest point of
the illuminating surface.
In the case of dipped headlamps, the minimum height in relation
to the ground is measured from the lowest edge of the reflector.
3.8.1. The position, as regards width, will be determined from the edge
of the illuminating surface which is the furthest from the median
longitudinal plane of the vehicle when referred to the overall
width, and from the inner edges of the illuminating surfaces
when referred to the distance between the lamps.
3.9. In the absence of specific requirements no lamps other than
direction indicator lamps and the hazard warning signal may
emita flashing light .
3.10. No red light which could give rise to confusion shall be emitted
from a lamp as defined in 1.5 in a forward direction, and no
white light which could give rise to confusion, other than from
the reversing lamp, shall be emitted from a lamp as defined in
1.5 in a rearward direction. No account shall be taken of lighting
devices fitted in the interior of the vehicle. This requirement is
considered to have been met if:
3.10.1. ►C1for the visibility of any red light ◄towards the front:
there must be no direct visibility of a light-emitting surface of a
red lamp if viewed by an observer moving within Zone 1 in a
transverse plane situated 25 m in front of the vehicle (see
Appendix 3, figure 1);
3.10.2. ►C1for the visibility of any white light ◄towards the rear:
there must be no direct visibility of a light-emitting surface of a
white lamp if viewed by an observer moving within Zone 2 in a
transverse plane situated 25 m behind the vehicle (see Appendix
3, figure 2).
3.10.3. Zones 1 and 2, as seen by the observer, are limited in their
respective planes as follows:
3.10.3.1. as regards height, by two horizontal planes which are 1 and 2·2 m
respectively above the ground;
3.10.3.2. as regards width, by two vertical planes which make an angle of
15º towards the front and rear respectively, and outside the
vehicle by reference to the median plane of the vehicle, passing
through the point (or points) of contacts of vertical planes which
are parallel with the median longitudinal plane of the vehicle,
and limiting the overall width of the vehicle.
If there are several points of contact, the one which is furthest
forward shall correspond to the front plane and the one furthest
rearward shall correspond to the rear plane.
3.11. The electrical connections must be such that the front and rear
position (side) lamps, the end-outline marker lamps if they exist,
and the rear registration plate lamp can only be switched on and
off simultaneously.
This is notvalid when using frontand rear posit ion (side) lamps
as parking lamps.
3.12. The electrical connections must be such that the main-beam and
dipped-beam headlamps, and the front and rear fog lamps cannot
be switched on unless the lamps referred to in 3.11 are also
switched on. This requirement shall not apply, however, to
main-beam or dipped-beam headlamps when their luminous
warnings consist of the intermittent lighting up at short intervals
of the main-beam headlamps or the intermittent lighting up at
short intervals of the dipped-beam headlamps or the alternate
lighting up at short intervals of the main-beam and dipped beam
headlamps.1976L0756 — EN — 14.12.1983 — 004.001 — 11

Appendix 5
Measurement of the variation of dipped beam inclination as a function of
load
1. SCOPE
This Appendix specifies a method for measuring variations in motor
vehicle dipped beam inclination, in relation to its initial inclination,
caused by changes in vehicle attitude due to loading.
2. DEFINITIONS
2.1.Initialinclination
2.1.1.Statedinitial inclination:
the value of the dipped beam initial inclination specified by the motor
vehicle manufacturer serving as a reference value for the calculation of
permissible variations.
2.1.2.Measuredinitial inclination:
the mean value of dipped beam inclination or vehicle inclination
measured with the vehicle in condition No 1, as defined in Appendix
1, for the category of vehicle under test. It serves as a reference value
for the assessment of variations in beam inclination as the load varies.
2.2. Dipped-beam inclination may be defined:
— either as the angle, expressed in milliradians, between the direction
of the beam towards a characteristic point on the horizontal part of
the cut-off in the luminous distribution of the headlamp and the
horizontal plane,
— or by the tangent of that angle, expressed in percentage inclination,
since the angles are small (for these small angles, 1 % is equal to
10 mrad).
If the inclination is expressed in percentage inclination, it can be calcu-
lated by means of the following formula:
h1/C0h2
l/C2100
where:
h1is the height above the ground, in millimetres, of the abovemen-
tioned characteristic point, measured on a vertical screen
perpendicular to the vehicle longitudinal median plane, placed at a
horizontal distance 1;
h2is the height above the ground, in millimetres, of the centre of refer-
ence (which is taken to be the nominal origin of the characteristic
pointchosen in h1);
l is the distance, in millimetres, from the screen to the centre of refer-
ence.
Negative values denote downward inclination (see Figure 1).Positive values denote upward inclination.
Figure 1
DippedbeamdownwardinclinationofacategoryM1vehicle1976L0756 — EN — 14.12.1983 — 004.001 — 35
▼M2
Notes:
1. This drawing represents a category M1vehicle, butt he principle
shown applies equally to vehicles of other categories.
2. Where the vehicle does not incorporate a headlamp levelling system,
the variation in dipped beam inclination is identical with the varia-
tion in the inclination of the vehicle itself.
3. MEASUREMENT CONDITIONS
3.1. If a visual inspection of the dipped beam pattern on the screen or a
photometric method is used, measurement shall be carried out in a
dark environment(for example, a dark room) of sufficientarea t o allow
the vehicle and the screen to be placed as shown in Figure 1. Headlamp
centres of reference shall be at a distance l from the screen of at least
10 m.
3.2. The ground on which measurements are made shall be as flat and hori-
zontal as possible, so that the reproducibility of measurements of
dipped beam inclination can be assured with an accuracy of ± 0·5 mrad
(± 0·05 % inclination).
3.3. If a screen is used, its marking, position and orientation in relation to
the ground and to the median longitudinal plane of the vehicle, shall
be such that the reproducibility of the measurement of the dipped
beam inclination can be assured with an accuracy of ± 0·5 mrad
(± 0·05 % inclination).
3.4. During measurements, the ambient temperature shall be between 10 and
30 ºC.
4. VEHICLE PREPARATION
4.1. Measurements shall be carried out on a vehicle which has travelled a
distance of between 1 000 and 10 000 km, preferably 5 000 km.
4.2. Tyres shall be inflated to the full-load pressure specified by the vehicle
manufacturer. The vehicle shall be fully replenished (fuel, water, oil)
and equipped with all the accessories and tools specified by the manu-
facturer. Full fuel replenishment means that the fuel tank must be filled
to not less than 90 % of its capacity as indicated in the information
document, a model of which appears in Annex I to Directive 70/156/
EEC.
4.3. The vehicle shall have the parking brake released and the gearbox in
neutral.
4.4. The vehicle shall be conditioned for at least 8 h at the temperature
specified in Item 3.4.
4.5. If a photometric or visual method is used, headlamps with a well-
defined dipped beam cut-off should preferably be installed on the
vehicle under test in order to facilitate the measurements.
Other methods may be employed to obtain a more precise reading (for
exemple, removal of the headlamp lens).
5. TEST PROCEDURE5.1.General
The variations in either dipped beam or vehicle inclination, depending
on the method chosen, shall be measured separately for each side of the
vehicle. The results obtained from both left and right headlamps under
all the load conditions specified in Appendix 1, shall be within the
limits set out in Item 5.5. The load shall be applied gradually without
subjecting the vehicle to excessive shocks.
5.2.Determinationofthemeasuredinitial inclination
The vehicle shall be prepared as specified in Item 4 and laden as speci-
fied in Appendix 1 (first loading condition of the respective vehicle
category).
Before each measurement, the vehicle shall be rocked as specified in
Item 5.4.
Measurements shall be made three times.1976L0756 — EN — 14.12.1983 — 004.001 — 36

5.2.1. If none of the three measured results differs by more than 2 mrad (0·2 %
inclination) from the arithmetic mean of the results, that mean shall
constitute the final result.
5.2.2. If any measurement differs from the arithmetic mean of the results by
more than 2 mrad (0·2 % inclination), a further series of 10 measure-
ments shall be made, the arithmetic mean of which shall constitute the
final result.
5.3.Measurementmethods
Any method may be used to measure variations of inclination provided
that the readings are accurate to within ± 0·2 mrad (± 0·02 % inclina-
tion).
5.4.Treatmentofvehicle ineachloadingcondition
The vehicle suspension and any other part likely to affect dipped beam
inclination shall be activated according to the methods described below.
However, the technical authorities and manufacturers may jointly
propose other methods (either experimental or based upon calculations),
especially when the test poses particular problems, provided such calcu-
lations are clearly valid.
5.4.1.M1category vehicles with conventional suspension
With the vehicle standing on the measuring site and, if necessary, with
the wheels resting on floating platforms (which must be used if their
absence would lead to restriction of the suspension movement likely to
affect the results of measurements), rock the vehicle continuously for at
least three complete cycles; for each cycle, first the rear and than the
frontend of t he vehicle is pushed down.
The rocking sequence shall end with the completion of a cycle. Before
making the measurements, the vehicle shall be allowed to come to rest
spontaneously. Instead of using floating platforms, the same effect can
be achieved by moving the vehicle backwards and forwards for at least
a complete wheel revolution.
5.4.2.M2,M3andN category vehicles with conventional suspension
5.4.2.1. If the treatment method for category M1vehicles described in Item
5.4.1 is not possible, the method described in Item 5.4.2.2 or 5.4.2.3
may be used.
5.4.2.2. With the vehicle standing on the measuring site and the wheels on the
ground, rock the body by temporarily varying the load.
5.4.2.3. With the vehicle standing on the measuring site and the wheels on the
ground, activate the vehicle suspension and all other parts which may
affect the dipped beam inclination by using a vibration rig. This can
be a vibrating platform on which the wheels rest.
5.4.3.Vehicles with non-conventional suspension, where the engine has to be
running
Before making any measurement wait until the vehicle has assumed its
final attitude with the engine running.
5.5.Measurements
The variation of the inclination of the dipped beam shall be assessed for
each of the different loading conditions in relation to the measured
initial inclination determined in accordance with Item 5.2.
If the vehicle is fitted with a manual headlamp-levelling system, the
latter shall be adjusted to the positions specified by the manufacturer
for given loading conditions (according to Appendix 1).
5.5.1. To begin with, a single measurement shall be made in each loading
condition. Requirements have been met if, for all the loading condi-
tions, the variation in inclination is within the calculated limits (for
example, within the difference between the stated initial inclination
and the lower and upper limits specified for approval) with a tolerance
of 4 mrad (0·4 % inclination).
5.5.2. If the result(s) of any measurement(s) does (do) not lie within the toler-
ance indicated in Item 5.5.1 or exceed(s) the limit values, a further
three measurements shall be made in the loading conditions corre-
sponding to this (these) result(s) as specified in Item 5.5.3.1976L0756 — EN — 14.12.1983 — 004.001 — 37
▼M2
5.5.3. For each of the above loading conditions:
5.5.3.1. If none of the three measured results differs by more than 2 mrad (0·2 %
inclination) from the arithmetic mean of the results, that mean shall
constitute the final result.
5.5.3.2. If any measurement differs from the arithmetic mean of the results by
more than 2 mrad (0·2 % inclination), a further series of ten measure-
ments shall be made, the arithmetic mean of which shall constitute the
final result.
5.5.3.3. If a vehicle is fitted with an automatic headlamp-levelling system which
has an inherent hysteresis loop, average results at the top and bottom of
the hysteresis loop shall be taken as significant values.
All these measurements shall be made in accordance with Items 5.5.3.1
and 5.5.3.2.
5.5.4. Requirements have been met, if, under all loading conditions, the varia-
tion between the measured initial inclination determined in accordance
with Item 5.2 and the inclination measured under each loading condi-
tion is less than the values calculated in Item 5.5.1 (without safety
margin).
5.5.5. If only one of the calculated upper or lower limits of variation is
exceeded, the manufacturer shall be permitted to choose a different
value for the stated initial inclination, within the limits specified for
approval.1976L0756 — EN — 14.12.1983 — 004.001 — 38

The controls for the headlamp-levelling devices referred to in Items
4.2.6.2.2ofAnnexI
1. SPECIFICATIONS
1.1. Downward inclination of the dipped beam must in all cases be produced
in one of the following ways:
(a) by moving a control downwards or to the left;
(b) by rotating a control in a counterclockwise direction;
(c) by depressing a button (push-pull control).
If several buttons are used to adjust the beam, the button which gives the
greatest downward inclination must be installed to the left or below the
button(s) for other dipped beam positions.
A rotary control which is installed edge-on, or with only the edge visible,
should follow the operating principles of controls of types (a) or (c).
1.1.1. This control must carry symbols indicating clearly the movements corre-
sponding to the downward and upward inclination of the dipped beam.
1.2. The ‘0’ position corresponds to the initial alignment according to Item
4.2.6.1 of Annex I.
1.3. The ‘0’ position which, according to Item 4.2.6.2.2 of Annex I, has to be
a ‘stop position’, need not necessarily be at the end of the scale.
1.4. The marks used on the control must be explained in the owner's hand-
book.
1.5. Only the following symbols may be used to identify the controls:
or
 and
Symbols employing five lines instead of four may also be used.
