COUNCIL DIRECTIVE
of 28June 1977
on the approximation of the laws of the Member States relating to
reversing lamps for motor vehicles and their trailers
(77/539/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 their reversing lamps;
Whereas these 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, inorder, in particular, to allow the EEC type-approval procedure whichwas the subject of Council Directive 70/156/EEC of 6 February 1970 onthe approximation of the laws of the Member States relating to thetype-approval of motor vehicles and their trailers(
3), to be introduced in
respect of each type of vehicle;
Whereas in Directive 76/756/EEC (4), the Council laid down the
common requirements for the installation of lighting and light-signallingdevices on motor vehicles and their trailers;
Whereas a harmonized component type-approval procedure for
reversing lamps makes it possible for each Member State to checkcompliance with the common construction and testing requirements andto inform the other Member States of its findings by sending a copy ofthe component type-approval certificate completed for each type ofreversing lamp; whereas the placing of an EEC component type-approval mark on all reversing lamps manufactured in conformity withthe approved type obviates any need for technical checks on thesereversing lamps in the other Member States;
Whereas it is desirable to take into account the technical requirements
adopted by the UN Economic Commission for Europe in its RegulationNo 23 (‘Uniform provisions concerning the approval of reversing lightsfor power-driven vehicles and their trailers')(
5) which is annexed to the
Agreement of 20 March 1958 concerning the adoption of uniformconditions for approval and reciprocal recognition of approval for motorvehicle equipment and parts;
Whereas the approximation of national laws relating to motor vehicles
entails reciprocal recognition by Member States of the tests carried outby each of them on the basis of the common requirements,

ANNEX III
PHOTOMETRIC MEASUREMENTS
1. MEASUREMENT METHODS
1.1. During photometric measurements, stray reflections shall be prevented by
appropriate masking.
1.2. Should the results of measurements be challenged, measurements shall be
carried out in such a way as to meet the following requirements:
1.2.1. the distance of measurement shall be such that the law of the inverse of
the square of the distance is applicable;
1.2.2. the measuring equipment shall be such that the angular aperture of the
receiver viewed from the reference centre of the lamp is between 10 /prime1and
1°;
1.2.3. the intensity requirement for a particular direction of observation shall be
satisfied if that requirement is met in a direction deviating by not morethan 15 /prime1from the direction of observation.
2. MEASURING POINTS EXPRESSED IN DEGREES OF ANGLE WITH
THE AXIS OF REFERENCE AND VALUES OF THE MINIMUMINTENSITIES OF THE LIGHT EMITTED
2.1. The directio nH=0 °a n dV=0 °corresponds to the axis of reference
(which, when the lamp is mounted on the vehicle, must be horizontal,parallel to the median longitudinal plane of the vehicle and oriented in therequired direction of visibility). It passes through the centre of reference.The values shown in the table give, for the various directions of measure-ment, the minimum intensities in cd.
2.2. If visual examination of a lamp appears to reveal substantial local vari-
ations of intensity, a check shall be made to ensure that no intensitymeasured between two of the directions of measurement referred to aboveis below 50 % of the lower minimum intensity of the two prescribed forthese directions of measurement.
