35. The expert from the Republic of Korea introduced a proposal (ECE/TRANS/WP.29/GRSG/2024/4 and amendment GRSG-127-38) to clarify that indicators, their identifications and the identifications of controls need not be illuminated when the driver intentionally deactivates illumination and the electric vehicle is not in driving conditions. The expert from the Netherlands requested a study reservation for further development. The expert from the United Kingdom questioned the need of amending the UN Regulation to provide this allowance and proposed to discuss it with the type approval authorities of his country and with all other interested parties to resolve this matter. GRSG agreed to resume consideration on this subject at its October 2024 session based on a revised proposal. At the same time, all interested parties were invited to liaise with the expert from the Republic of Korea to further develop the proposal.

25. The expert from the Republic of Korea introduced GRSG-128-07, to update GRSG on the discussion of a proposal (ECE/TRANS/WP.29/GRSG/2024/4) he had introduced during the April session of the Working Group. He reminded GRSG that the proposal aimed to clarify that indicators, their identifications and the identifications of controls need not be illuminated when the driver intentionally deactivates illumination and the electric vehicle is not in driving conditions. However, during an online session of interested parties, held on 3 September 2024 it was agreed that no amendment was not needed. He added that further discussion was needed on the safety concepts related to warning signals for battery use, mandatory telltales based on vehicle status, and the definitions of vehicle states (driving mode and parking mode). Finally, GRSG agreed on the above-mentioned conclusions and agreed to leave the text of the UN Regulation unchanged on this subject. It was expected that discussion would continue at the GRSG April 2025 session on above-mentioned safety concepts.

22. The expert from the Republic of Korea withdrew ECE/TRANS/WP.29/GRSG/2024/4 and GRSG-128-07. The expert from the Kingdom of the Netherlands introduced GRSG-129-15, that updates the ISO standard by taking into account new features and associated symbols. GRSG adopted GRSG-129-15, as reproduced in annex VI to the report and requested the secretariat to submit it as the proposal of supplement 7 to the 01 series of amendments to UN Regulation No. 121 for consideration and vote at the November 2025 sessions of WP.29 and AC.1.
