COUNCIL DIRECTIVE
of 28 June 1977
on the approximation of the laws of the Member States relating to
rear fog lamps for motor vehicles and their trailers
(77/538/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 rear fog lamps;
Whereas these requirements differ from one Member State to another;
whereas it is therefore necessary that all Member States adopt the same
requirements either in addition to or in place of their existing rules, in
order, in particular, to allow the EEC type-approval procedure which was
the subject of Council Directive 70/156/EEC of 6 February 1970 on the
approximation of the laws of the Member States relating to the
type-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-signalling
devices on motor vehicles and their trailers;
Whereas a harmonized component type-approval procedure for rear fog
lamps makes it possible for each Member State to check compliance with
the common construction and testing requirements and to inform the
other Member States of its findings by sending a copy of the component
type-approval certificate completed for each type of rear fog lamp;
whereas the placing of an EEC component type-approval mark on all rear
fog lamps manufactured in conformity with the approved type obviates
any need for technical checks on these rear fog lamps in the other
Member States;
Whereas it is desirable to draft the technical requirements so that they
have the same aim as the work being carried out on the subject in the UN
Economic Commission for Europe;
Whereas the approximation of national laws relating to motor vehicles
entails reciprocal recognition by Member-States of the tests carried out
by each of them on the basis of the common requirements,
HAS ADOPTED THIS DIRECTIVE:
Article 1
1. Each Member State shall grant EEC component type-approval for
any type of rear fog lamp which satisfies the construction and testing
requirements laid down in Annexes 0, II and III.
2. The Member State which has granted EEC component type-approval
shall take the measures required in order to verify that production models
conform to the approved type, in so far as this is necessary and if need be
in cooperation with the competent authorities in the other Member
States. Such verification shall be limited to spot checks.!B

Article 2
Member States shall for each type of rear fog lamp which they approve
pursuant to Article 1, issue to the manufacturer, or to his authorized
representative, an EEC component type-approval mark conforming to the
model shown in Annex II.
Member States shall take all appropriate measures to prevent the use of
marks liable to create confusion between rear fog lamps which have been
type-approved pursuant to Article 1, and other devices.
Article 3
1. No Member State may prohibit the placing on the market of rear fog
lamps on grounds relating to their construction or method of functioning
if they bear the EEC component type-approval mark.
2. Nevertheless, a Member State may prohibit the placing on the
market of rear fog lamps bearing the EEC component type-approval
mark which consistently fail to conform to the approved type.
That State shall inform the other Member States and the Commission
forthwith of the measures taken, specifying the reasons for its decision.
Article 4
The competent authorities of each Member State shall within one month
send to the competent authorities of the other Member States a copy of
the component type-approval certificates, an example of which is given
in Annex I, completed for each type of rear fog lamp which they approve
or refuse to approve.
Article 5
1. If the Member State which has granted EEC component type-appro-
val finds that a number of rear fog lamps bearing the same EEC
component type-approval mark do not conform to the type which it has
approved, it shall take the necessary measures to ensure that production
models conform to the approved type. The competent authorities of that
State shall advise those of the other Member States of the measures taken
which may, where there is consistent failure to conform, extend to
withdrawal of EEC component type-approval. The said authorities shall
take the same measures if they are informed by the competent authorities
of another Member State of such failure to conform.
2. The competent authorities of Member States shall inform each other
within one month of any withdrawal of EEC component type-approval,
and of the reasons for such a measure.
Article 6
Any decision taken pursuant to the provisions adopted in implementation
of this Directive, to refuse or withdraw EEC component type-approval
for a rear fog lamp or prohibit its placing on the market or use shall set
out in detail the reasons on which it is based. Such decision shall be
notified to the party concerned, who shall at the same time be informed
of the remedies available to him under the laws in force in the Member
States and of the time limits allowed for the exercise of such remedies.
Article 7
No Member State may refuse to grant EEC type-approval or national
type-approval of any vehicle on grounds relating to its rear fog lamps if
these bear the EEC component type-approval mark and are fitted in
accordance with the requirements laid down in Directive 76/756/EEC.!B1977L0538 — EN — 01.01.1981 — 001.001 — 3
Article 8
No Member State may refuse or prohibit the sale, registration, entry into
service or use of any vehicle on grounds relating to its rear fog lamps if
these bear the EEC component type-approval mark and are fitted in
accordance with the requirements laid down in Directive 76/756/EEC.
Article 9
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 km/h, and its
trailers, with the exception of vehicles which run on rails, agricultural or
forestry tractors and machinery and public works vehicles.
Article 10
Any amendments necessary to adjust the requirements of the Annexes to
take account of technical progress shall be adopted in accordance with
the procedure laid down in Article 13 of Directive 70/156/EEC.
Article 11
1. Member States shall bring into force the provisions needed in order
to comply with this Directive within 18 months of its notification and
shall forthwith inform the Commission thereof.
2. Member States shall ensure that the texts of the main provisions of
national law which they adopt in the field covered by this Directive are
communicated to the Commission.

appropriate masking.
2. The measurements shall be carried out in such a way as to meet the
following requirements:
2.1. the distance of measurement shall be such that the law of the inverse of
the square of the distance is applicable;
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 ’and
