Agenda Item 7. (f) Regulation No. 87
This agenda item relates to UN R87 Daytime Running Lamps.

33. GRE noted that document ECE/TRANS/WP.29/GRE/2015/33 on tell-tales was discussed together with ECE/TRANS/WP.29/GRE/2015/31 (para. 13 above).

34. The expert from Japan presented the outcome of a study on daytime running lamps (DRL) (GRE-74-20). The purpose of the study was to verify the effects of DRL on road traffic in Japan from the perspectives of other road users (glare and visibility for pedestrians and oncoming vehicle drivers) as well as to check the conspicuity of a motorcycle in front of the four-wheeled vehicle with DRL. The test conditions included different levels of sky illuminance and DRL intensity. According to the expert, the study did not identify negative effects of DRL. He also pointed out that, based on the study results, legal consultations had started in Japan with the aim to find a solution for DRL for the purposes of listing Regulation No. 48 in an annex to UN Regulation No. 0. GRE commended Japan for such a comprehensive study and welcomed its outcome.
