Proposal to allow under specified conditions the use of logos inside the illuminating surface of a signalling lamp.

Proposal to introduce provisions:

1. For vehicles intended for use by the armed services and forces responsible for maintaining public order: the manual switching off of all lighting devices in all circumstances;
2. In the absence of a “vehicle door assistance and warning system”: the mandatory application of the hazard warning lights to reduce the safety risks in the case a door is opened to the traffic side.

Proposal to allow the manual switching off all lighting devices in all circumstances for vehicles intended for use by the armed services and forces responsible for maintaining public order.

Proposal to introduce requirements for testing the sun load impact, which can delay the perception of a signal in such a way that it may became a serious safety issue, if the sun load impact goes above a defined ratio.

Proposal to allow the use of logos inside the illuminating surface of a signalling lamp under certain conditions.

Proposal to allow the use of manufacturer logos in the internal structure of optical components and/or in the outer lens within the apparent surface of a signalling lamp.

Proposal to allow the use of manufacturer logos inside the illuminant surface of a signalling lamp.

Proposal to allow the use of manufacturer logos inside the illuminant surface of a signalling lamp.

Proposal to clarify the requirements for the installation of the foremost side-marker lamp of 3 m from the front, which cannot always be achieved in case of semi-trailers.

Proposal to introduce provisions concerning automated driving systems and driver support features based on terms “driving system” and “driving mode”.

Proposal to clarify that only light-signalling devices may incorporate an illuminated logo.

Proposal to clarify that only light-signalling devices may incorporate an illuminated logo.

Proposal to enable the use of alternate colors (per footnote 18 of Table 1 and in line with ISO Standard 2575) for certain lighting tell-tales in order to indicate light source failures in response to the proposals for light failure indicators under UN Regulations Nos. 7, 48 and 87 (GRE/2016/7, GRE/2016/12 and GRE/2016/17) as adopted by GRE. This proposal anticipates use of the same approach in response to plans for additional failure indication requirements for other lighting regulations.

Draft revision of the regulation on the installation of lighting equipment that incorporates the draft proposal for a horizontal reference document covering provisions used across other lighting regulations.

This document is also available in German.

Idea from Germany to simplify the lifetime requirements for non-replaceable light source(s) and non-replaceable light source module(s) given that the lifetime of a LED light source is much higher than the lifetime of a filament lamp.

Proposal to improve the visibility of direction indicators. The proposal modifies UN R48 and UN R148 requirements for direction indicator lamps grouped with stop lamps. Key changes include: requiring 75% of the rear direction indicator’s apparent surface to be more than 25mm from the stop lamp; positioning direction indicators at specified distances from the vehicle’s outer edge; and establishing a minimum apparent surface area of 30cm² for rear direction indicators. The justification cites existing installations showing inadequate visibility and references luminance studies supporting the 30cm² minimum area requirement.

A literature review on direction indicator visibility presents research on vehicle lighting design, visibility, and signalling. Sources include studies on overlapping and interlocking of lights, and dynamic evaluation of automobile rear lighting configurations.
