Rear-registration-plate illuminating devices and retro reflectors shall likewise be regarded
as lamps;
2.6.1. "Equivalent lamps" means lamps having the same function and authorized in the
country in which the vehicle is registered; such lamps may have different characteristics
from those of the lamps with which the vehicle is equipped at the time of approval on
condition that they satisfy the requirements of this Regulation;
2.6.2. "Independent lamps" means devices having separate apparent surfaces in the
direction of the reference axis, separate light sources, and separate lamp bodies;
2.6.3. "Grouped lamps" means devices having separate lenses and separate light sources,

electrical differences), totally or partially common apparent surfaces in the direction of
the reference axis and a common lamp body;
2.6.6. "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 the bodywork;
2.6.7. "Lamps of variable position" means lamps installed on the vehicle which can move in
relation to the vehicle, without being detached;
2.6.8. "Main-beam headlamp" means the lamp used to illuminate the road over a long
distance ahead of the vehicle;

distributed lighting or light-signalling system not having a built-in outer lens.
2.6.29. "Interdependent lamp system" means an assembly of two or three interdependent
lamps providing the same function.
2.6.29.1. "Interdependent lamp" means a device operating as part of an interdependent lamp
system. Interdependent lamps operate together when activated, have separate apparent
surfaces in the direction of the reference axis and separate lamp bodies, and may have
separate light source(s).
2.7. "Illuminating surface" (see Annex 3)
2.7.1. "Illuminating surface of a lighting device" (Paragraphs 2.6.8., 2.6.9., 2.6.10., 2.6.11.
and 2.6.25.) means the orthogonal projection of the full aperture of the reflector, or in the
case of headlamps with an ellipsoidal reflector of the "projection lens", on a transverse
plane. If the lighting device has no reflector, the definition of Paragraph 2.7.2. shall be
applied. If the light emitting surface of the lamp extend(s) over part only of the full
aperture 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 lens are adjustable relative
to one another, the mean adjustment should be used;
2.7.2. "Illuminating surface of a light-signalling device other than a retro reflector"
(Paragraphs 2.6.12. to 2.6.20., 2.6.23. and 2.6.24.) 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 to verify the distance to the extreme edges
of the vehicle and the height above the ground.
For other applications of the illuminating surface, e.g. distance between two lamps or
functions, the shape of the periphery of this illuminating surface shall be used. The
screens shall remain parallel, but other orientations are allowed to be used.
In the case of a light-signalling device whose illuminating surface encloses either totally
or partially the illuminating surface of another function or encloses a non-lighted surface,
the illuminating surface may be considered to be the light emitting surface itself (see e.g.
Annex 3).

2.12. "Extreme outer edge" on either side of the vehicle means the plane parallel to the
median longitudinal plane of the vehicle and touching its lateral outer edge, disregarding
the projection:

parts; or
Any assembly of two independent lamps, whether identical or not, having the
same function, both approved as type "D" lamp and installed so that:
(i)
(ii)
The projection of their apparent surfaces in the direction of the reference
axis occupies not less than 60% of the smallest quadrilateral circumscribing
the projections of the said apparent surfaces in the direction of the
reference axis; or
The distance between two adjacent/tangential distinct parts does not
exceed 15mm when measured perpendicularly to the reference axis; or
