Revised proposal to clarify the requirements for light sources in the lighting and light-signalling Regulations listed in Annex 4 to Regulation No. 0 on the International Whole Vehicle Type Approval (IWVTA) pursuant to GRE-77 discussions.

Proposal to clarify and amend the supplement concerning sequential direction indicators adopted by GRE during its 76th session based upon document GRE/2016/20 and finalized in Annex IV of the session report. The proposal would clarify and move the prohibition against the mixing of signals of two or more activation modes to UN R48 and introduces transitional provisions.

The 05 and 06 series of amendments provide for automatic adjustment of lamps based on ambient light conditions. To avoid misuse of the daytime running lamps (DRL), automatic switching between DRL and dipped-beam headlamps is preferable; however, manual switching for specific cases is still necessary. Under the transitional provisions for series 05 of amendments, only automatic switching would be permissible after 30.7.2016 (for new type of categories M1 and N1 vehicles) and after 30.1.2018 (for new type of other categories vehicles). Nonetheless, in the transitional provisions for series 06 of amendments, the same transitional period appears to have been unintentionally omitted. This proposed supplement corrects this mistake in the 06 series by deleting the alternatives to the automatic switching from the 06 series of amendments:

1. deletion of paragraphs 6.2.7.6.2 and 6.2.7.6.3;
2. merging and rewording of paragraphs 6.2.7.5 and 6.2.7.6;
3. consequent editorial adjustment in paragraph 5.11.1.3. and 6.19.7.4. to maintain acceptable the rear position lamps switching possibility allowed by the present text;
4. small editorial changes to better clarify that an automatic switching based on different factors in respect to those prescribed in paragraph 6.2.7.5. (new numbering) are allowed only as supplemental condition;
5. other editorial changes and renumbering for text and numbering coherence.
