A single lamp definition
A single lamp means:
(a) A device or part of a device having one lighting or light-signalling function, one or more light source(s) and one apparent surface in the direction of the reference axis, which may be a continuous surface or composed of two or more distinct parts; or
(b) 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) The projection of their apparent surfaces in the direction of the reference axis occupies not less than 60 per cent of the smallest quadrilateral circumscribing the projections of the said apparent surfaces in the direction of the reference axis; or
(ii) The distance between two adjacent/tangential distinct parts does not exceed 15 mm when measured perpendicularly to the reference axis; or
(c) Any assembly of two independent retro-reflectors, whether identical or not, that have been approved separately and are installed in such a way that:
(i) The projection of their apparent surfaces in the direction of the reference axis occupies not less 60 per cent of the smallest quadrilateral circumscribing the projections of the said apparent surfaces in the direction of the reference axis; or
(ii) The distance between two adjacent/tangential distinct parts does not exceed 15 mm when measured perpendicularly to the reference axis. or
(d) Any interdependent lamp system composed of two or three interdependent lamps providing the same function, approved together as type "Y" and installed so that the distance between adjacent apparent surfaces in the direction of the reference axis does not exceed 75 mm when measured perpendicularly to the reference axis.
A single lamp means:
(a) A device or part of a device having one lighting or light-signalling function, one or more light source(s) and one apparent surface in the direction of the reference axis, which may be a continuous surface or composed of two or more distinct parts; or
(b) Any assembly of two lamps marked "D", whether identical or not, having the same function; or
(c) Any assembly of two independent retro-reflectors, whether identical or not, that have been approved separately; or
(d) Any interdependent lamp system composed of two or three interdependent lamps marked "Y" approved together and providing the same function."
A single lamp means a device or part of a device, having one function and one apparent surface in the direction of the reference axis (see paragraph 2.8. of this Regulation) and one or more light sources.

More Definitions of A single lamp
A single lamp means a device or part of a device, having one function and one apparent surface in the direction of the reference axis (see paragraph 2.6. of this Regulation) and one or more light sources. For the purpose of installation on a vehicle, a "single lamp" also means any assembly of two independent or grouped lamps, whether identical or not, having the same function, if they are installed so that the projection of their apparent surfaces in the direction of the reference axis occupies not less than 60 per cent of the smallest rectangle circumscribing the projections of the said apparent surfaces in the direction of the reference axis. In such a case, each of these lamps shall, where approval is required, be approved as a type "D" lamp. This possible combination does not apply to driving beam headlamps and passing beam headlamps.
A single lamp means:
(a) a device or part of a device having one lighting or light-signalling function, one or more light source(s) and one apparent surface in the direction of the reference axis, which may be a continuous surface or composed of two or more distinct parts, or
(b) any assembly of two independent lamps, whether identical or not, having the same function, both approved as type "D" lamp and installed so that the projection of their apparent surfaces in the direction of the reference axis occupies not less than 60 per cent of the smallest quadrilateral circumscribing the projections of the said apparent surfaces in the direction of the reference axis.
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, the 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.
A single lamp means a device or part of a device having one lighting or light- signalling function, one or more light source(s) and one apparent surface in the direction of the reference axis, which may be a continuous surface or composed of two or more distinct parts.
A single lamp means a device or part of a device having one lighting or light- signalling function, one or more light source(s) and one apparent surface in the direction of the reference axis, which may be a continuous surface or composed of two or more distinct parts, or any assembly of two independent lamps as defined by an applicable regulations of a Contracting Party.]
A single lamp means:(a) a device or part of a device having one lighting or light-signalling function, one or more light source(s) and one apparent surface in the direction of the reference axis, which may be a continuous surface or composed of two or more distinct parts,; or(b) Any assembly of two lamps marked "D", whether identical or not, having the same function, or(c) Any assembly of two independent retro-reflectors, whether identical or not, that have been approved separately; or(d) Any interdependent lamp system composed of two or three interdependent lamps marked "Y" approved together and providing the same function. 2.15. "Distance between two lamps" which face in the same direction means the shortest distance betweenthe two apparent surfaces in the direction of the reference axis.
