Proposal to supersede the current guidelines for regulatory procedures and transitional provisions for UN Regulations (document WP.29/1044 and its Revision 1) with updated general guidelines for establishing or amending UN Regulations, including for the definition of scope, administrative and transitional provisions, use of alternative requirements, and cross-referencing with other regulations. This proposal aims to

1. Streamline future work without superseding provisions of the 1958 Agreement and the existing UN Regulations,
2. Clarify rulemaking procedures pursuant to Revision 3 of the 1958 Agreement, and
3. Ensure “good regulatory practice” through clarifications to avoid divergence between the interpretation of Revision 3 and the application to UN Regulations.

Correction to align the French text with the English and Russian versions.

Request for guidance regarding interpretation of UN lighting rules:

1. Is it allowed that the shape of the apparent surface can be the logo of the manufacturer brand or other brand-identifying figures?
2. Is it allowed that the shape of the apparent surface can be the same as an evocative/suggestive figure? Even as an informative figure such as road traffic
   signs?
3. Is the advertising lighting allowed at the national level in the Contracting parties, regarding to its influence on road safety and distraction?
4. Do we have to consider an apparent surface, whose shape is the logo of a brand manufacturer or other brand-identifying figures, as a advertising lighting?

Proposal to delete footnote ¹⁸ of Table 1 regarding telltale no. 1 (Master lighting switch) when it is combined with telltale no. 19 (Position, side marker, and/or end-outline marker lamps). The footnote is redundant and potentially confusing since UN R121 already refers to paragraph 5. of ISO 2575-2004 which states, “A given symbol may be shown in more than one of the colours specified in 5.1 in order to convey a change in the operating condition.”

Proposal to insert Footnote 18 for Tell-tale 1 (Master lighting switch) stating, “Symbol may be shown in other colours than specified in column 5 in order to convey different meanings according to the general colour coding as proposed in paragraph 5. of ISO 2575-2004.”
