    1. ‘Illuminating surface of a reflex reflector’ (point 1.5.20) means the orthogonal projection of the reflecting surface of the reflex reflector in a plane perpendicular to its 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.
    2. If natural light is totally excluded, low level night lighting should be provided to allow animals to retain some vision and to take account of their startle reflex.
    3. ‘Reflex reflector’ means a device used to indicate the presence of a tractor by the reflection of light emanating from a light source not connected to the tractor, the observer being situated near the source.
    4. If natural light is totally excluded, low-level night lighting (5 to 10 lux) should be provided to allow dogs to retain some vision and to take account of their startle reflex.
    5. If natural light is totally excluded, low level night lighting (5 to 10 lux) should be provided to allow cats to retain some vision and to take account of their startle reflex.
    6. ‘Illuminating surface of a signalling lamp other than a reflex reflector’ (points 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.
