Proposal to introduce new criteria on the automatic leveling of headlamps based on GTB glare and visibility studies. This proposal is for formal consideration and advice from Contracting Parties, with the expectation that a finalized text will be submitted for adoption at the seventy-fourth session of GRE.

Proposal to introduce provisions for “side-illuminating lamps” that aim to improve the driver’s visibility over the opposite side of the road (on-coming traffic side) and its buffer zone to mitigate the impact of glare from on-coming vehicles.

Proposal to delete the requirement for automatic leveling devices for all headlamps with light emitting diode (LED) light sources based upon the results of the GTB glare study. The proposal argues that the restriction discriminates against LED light sources based upon an erroneous understanding of light-source relevance to driver glare.

Proposal to introduce provisions for “side-illuminating lamps” that aim to improve the driver’s visibility over the opposite side of the road (on-coming traffic side) and its buffer zone to mitigate the impact of glare from on-coming vehicles. This submission supersedes the earlier formal document GRE/2015/6.

Proposal to reduce glare problems for drivers by deleting the exemption in Regulation No. 48 that allows manual leveling for dipped-beam headlamps, effectively mandating automatic leveling.

Comments on the proposal to introduce new requirements for automatic leveling systems as a means to reduce driver glare (document GRE/2015/5).

Comments on document GRE/2015/6 proposing to introduce provisions for “side-illuminating lamps” that aim to improve the driver’s visibility over the opposite side of the road (on-coming traffic side) and its buffer zone and to mitigate the impact of glare from on-coming vehicles.

Proposal to improve the applicability of paragraph 5.7.1.3.1. (concerning the separation of grouped direction indicator and stop lamps in order to avoid “signal mix”). To improve the present requirements of paragraph 5.7.1.3.1.on the basis of the colour changes concept, three alternative approaches for a suitable separation of direction indicator lamps and stop lamp are proposed:
a) the improved test of the existing paragraph 5.7.1.3.1. clarifies its application to lamps composed of more than one part and deletes the concept of “adjacent” parts of the lamps (that in the past led to different interpretations) in favour of a description of the condition of application of the requirement;
b) the unchanged text of the following paragraph 5.7.1.3.2.;
c) a new paragraph 5.7.1.3.3. to provide for specific electrical connections of the involved functions, in conjunction with the requirements of paragraph 5.9.2.

Discussions have arisen within GRRF concerning failure warnings for trailer direction indicators and brake lights. This paper alerts GRE to the absence of a standardized approach to communicating such lighting failures for trailers which may be a subject for consideration under UN R48.
