Discussion document on tell-tale requirements in Regulation No. 48 versus Regulation No. 121 and consideration of establishing a task force to further discuss the issues involved. Pursuant to discussions at the previous two GRE sessions concerning the use of the term “failure tell-tale” in relation to daytime running lamps and adaptive front lighting systems (AFS) in UN R48 and the potential impact on UN R121 concerning the “location and identification of hand controls, tell-tales and indicators”, the Netherlands proposes the formation of a special task force to study the issues and propose draft amendments for lighting regulations as warranted.
15. The expert from the Netherlands recalled the GRE considerations, at its sixty-ninth and seventieth sessions, of tell-tale requirements and the possible need for aligning UN Regulation No. 48 with relevant requirements contained in UN Regulation No. 121. Given the complexity of the issue, he suggested continuing with more in-depth discussions on these issues in a smaller group of interested experts (GRE-71-11). Following this request, GRE consented to establishing a taskforce on tell-tale requirements, for which the expert from the Netherlands would act as Chair and OICA as secretary. GRE decided to keep this issue on the agenda and requested the task force to report on its findings at the next session of GRE.
