Proposal from Poland to introduce performance-based distance and glare criteria for headlamps, making automatic levelling provisions independent of the luminous flux of the light source.

Presentation of the Polish Motor Transport Institute in support of the proposal to replace fixed values for headlamp aiming and tolerances with performance-based specifications.

Revised version of Poland’s proposal (GRE/2012/21) to introduce performance-based distance and glare criteria for headlamps, replacing the fixed 2000 lm luminous flux condition as a criterion of the automatic leveling requirement.

Submission from Poland to replace the artificial 2,000 lm borderline and LED automatic levelling requirements with performance-based distance and glare criteria for headlamps.

Poland’s response to comments submitted by OICA (document GRE-68-20) regarding document GRE/2012/27 concerning the influence of headlamp initial aiming and leveling tolerances on road illumination distance.

Submitted by Poland to replace document GRE/2012/27 proposing an alternative set of requirements for the initial aiming of dipped-beam headlamps and allowing to remove the artificial 2,000 lm borderline and Light Emitting Diode (LED) automatic levelling.

Proposal to introduce an alternative set of performance-based requirements for the initial aiming of dipped-beam headlamps and allowing removing the artificial 2,000 lm borderline and Light Emitting Diode (LED) automatic leveling. This document supersedes document GRE/2013/15.

Revised presentation in support of document GRE/2013/57 proposing to introduce an alternative set of performance-based requirements for the initial aiming of dipped-beam headlamps and allowing removing the artificial 2,000 lm borderline and Light Emitting Diode (LED) automatic leveling.

Text prepared by Poland to introduce an alternative set of performance-based requirements for the initial aiming of dipped-beam headlamps and allowing removing the artificial 2,000 lm borderline and Light Emitting Diode (LED) automatic levelling.

Proposal to introduce type-approval provisions for lamps intended to provide supplemental lateral illumination of the road on the driver-side of the vehicle as a means to reduce the impact of glare from on-coming vehicle headlamps on driver vision and road visibility.

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.

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

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.

Comments on the VGL informal group draft justification of its headlamp glare requirements.

Examples of loading situations and their influence on headlamp inclination cut-off.

Additional questions from Poland to OICA for clarification the expectations concerning 1.6% cut-off inclination limits range as a result of non-repeatability of vehicles according Reg. 48 load/pitch test (Annex 5 and 6).

Proposal for changes to the discussion document presenting potential new requirements for headlamp levelling, in particular regarding the vertical inclination in relation to the dipped-beam headlamp mounting height.

Supporting data justifying the headlamp aiming and cut-off points diagrammed in the proposal for a new series of amendments (GRE-81-13).

Proposal to align UN R48 with provisions in UN R4 by introducing parameters for luminance levels, maximum gradient value, angles of visibility and light incidence angle which are necessary to determine the geometric position of devices in relation to the rear registration plate.

The IWG-VGL group proposed that the CoP requirements would be the same as for the type-approval. Therefore, Poland will not support the proposal to extend them by another 0.4%.

Proposal to add a reference to the installation parameters of the licence plate illumination lamps determined during their type approval process. Every type-approved device or pair of devices have their own geometrical position in relation to the rear registration plate which is determined based on the illumination levels, maximum gradient value, angles of visibility and light incidence angle. This proposal would introduce a reference to these parameters in UN R48.

Proposal to introduce new requirements for headlamp levelling, in particular on the vertical inclination in relation to the dipped-beam headlamp mounting height, and to allow manual levelling only for off-road vehicle. Amendments to ECE/TRANS/WP.29/GRE/2020/8/Rev.2; new series of amendments

The document analyzes separating direction indicators and stop lamps. It examines how drivers recognize lighting functions through visual perception and notes that irregular lamp shapes increase reaction time. The document states that “apparent surface”, currently defined only through manufacturer drawings, lacks perceptual grounding because it ignores luminance distribution and edge contrast. It recommends minimum lamp sizes and distances based on visual acuity, minimum luminance requirements, and a 3:1 luminance contrast between functions when spatially merged in one lamp.
