End October, GRE held its 85th session. Important decisions were taken:
The first step for road projections was approved (document GRE-85-33) and will be submitted to the WP.29 session in June 2022 for final adoption. These road projections are part of the ADB and a new annex in R48 has been created to list which symbols and patterns are allowed. This is a great news and an important first step. We shall thank GTB and its members from Working Group Front Lighting and Working Group Installation for this great achievement after much workover the last 2 years. This text will open new doors for the future with the possibility to extend to other road projections and signalling projections (GTB Working Group Signal Lighting presented also a document GRE-85-38 to explain on what they are working and how it could help safety).
A lot of comments were received, showing the interest for this topic.
After more than 2 years of discussion, the final text that opens the possibility to have lit logo was approved during the GRE session (GRE/2020/5/Rev.2 as amended by GRE-85-26). Final adoption by WP.29 will also be in June 2022. Lit logos will be allowed with some limitations (size, number, position, part of only certain functions) but will create some new era for designers and car makers, without too much light pollution and advertising, really a good compromise that could explain the duration between the first discussions and the final text.
01 series of R148, R149 and R150 (device regulations) were finally approved after an intensive work done by the SLR group with monthly meeting, with significant modifications and improvements. Especially new photometrical grids for passing-beam and driving-beam with new headlamp classes have been approved.
GTB presented also a document (GRE-85-37) about the willingness to investigate how the lighting community could reduce power consumption in relation with legal requirements. GRE noted with interest this document and GTB will start investigations with universities to see what could be changed in existing lighting functions without reducing safety, especially in some specific conditions (city with street light, traffic jam, platooning, ..)
Discussion still continues about autonomous vehicles and their need for specific light-signalling requirements. GRE is in close contact now with GRVA about this topic. A synthesis was done by the chairman of the AVSR task force (GRE 85-34).
The ongoing debate about Mandatory Automatic Headlamp Levelling continues. GRE did not reach a decision and deferred to the next session in April 2022.
