Paragraph 3.2.4. now refers to paragraph 2.5.1. for the definition of the illuminating surface. Before this supplement, it referred to paragraph 2.7.1. Paragraph 5.9. now refers to paragraph 2.3. for the definition of a lamp, in two places. Before this supplement, both places referred to paragraph 2.5.

This information is not necessary in the case of the rear registration plate lamp (as defined in UN Regulation No. 48).
No red light which could give rise to confusion shall be emitted from a lamp as defined in paragraph 2.52.3. in a forward direction and no white light which could give rise to confusion, shall be emitted from a lamp as defined in paragraph 2.52.3. in a rearward direction.
