Reference to Annex 8, paragraph 4, in paragraph 6.1.1. (conformity of production)
Paragraph 6.1.1. now also names Annex 8, paragraph 4. Approved road illumination devices must meet Annex 8, paragraph 4, and paragraphs 4.16. and 5. to conform to the type approved.

Q2Why it changed
- Proposed by
- Experts from the International Automotive Lighting and Light-Signalling Expert Group (GTB)
- Working party
- GRE, 92nd session (April 2025)
Reasons
GTB proposed to correct the wrong numbering of paragraph 4.11., because it could lead to misunderstandings.
Sources (2)
“Proposals A and B aim to correct the currently wrong numbering of paragraph 4.11. which could lead to misunderstandings.”
“The expert of GTB proposed correcting the numbering in paragraph 4.11.”
Paragraph 4.11.1. contained the explanation of the testing of electromechanical structures, which should also apply to sub-paragraphs 4.11.2., 4.11.3. and 4.11.4. For this reason, it was proposed that this explanation become part of the head paragraph 4.11.

“For this reason, such explanation is proposed to become part of the head paragraph 4.11.”
Annex 8, paragraph 4, describes the provisions for conformity of production for all devices (except cornering lamps) incorporating a lens of plastic material. The reference in the body text was missing. The proposal is intended to correct this by adding a reference to Annex 8, paragraph 4, in paragraph 6.1.1.
