GRE/2012/26 is a proposal from the Working Party “Brussels 1952” (GTB) to update provisions on heat resistance tests. This correction from GTB provides an improved justification for the proposed amendments.

Document GRE/2012/39 ( a proposal to introduce interdependent lamps (“Y” Lamps) into UN R87) did not take into account document WP.29/2012/78 submitted for adoption by WP.29 at its 158th (November 2012) session. Therefore, GTB proposes this new document to replace GRE/2012/39.

GRE/2012/40 is a proposal from the Working Party “Brussels 1952” (GTB) introducing a new category LW2 into the new draft Regulation for LED light sources [UN R127] and introducing some editorial amendments to the existing text. GTB proposes this correction to better align its wording with UN R37.

GTB presentation on the potential ramifications of the electronic type-approval database (DETA) on lighting markings and regulations. GTB plans to discuss these issues at its Oct 29- 1 Nov 2012 assembly in Seattle (USA).

UN R7 has no requirements concerning changes in luminance of a lamp. Therefore, certain lamps which could not be installed in accordance with UN R48 could nonetheless obtain type approval and be sold in the aftermarket. This proposal would prevent such an occurrence.

Proposal to delete the exemption for category M1 and N1 vehicles from the requirement for a minimum distance between the inner edges of two adjacent lighting surfaces.

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.

Presentation of Polish opinion poll results in support of document GRE/2012/27, the proposal to replace the artificial 2,000 lm borderline and LED automatic leveling requirements with performance-based distance and glare criteria for headlamps.

Additional supporting arguments for the proposal to modify the photometric performance requirements of front position lamps integrated with front fog lamps and of rear position lamps integrated with rear fog lamps (analogous to the treatment of position lamps integrated into headlamps).

Presentation with additional refinements to the submission from Poland to replace the artificial 2,000 lm borderline and LED automatic leveling requirements with performance-based distance and glare criteria for headlamps.

Presentation concerning China proposal to clarify definitions concerning testing of “resistance to atmospheric agents”.

Presentation reviewing flasher signals and technological advances in support of developing clearer parameters within UN R6 and R48 to govern variations of light signals.

Review of a study on driver perceptions of direction indicator performance.

Presentation on the GTB’s Coordination of Automotive Visibility and Glare Studies (CAVGS) task force activities.

Presentation on GTB survey of literature related to glare and visibility issues including accident data, visual acuity research, lamp aiming, etc.

Update on the CAVGS task force activities.

SAE comments on the Chinese proposal to update the ‘resistence to atmospheric agents’ test by applying the spectral energy distribution of sunlight as defined in CIE Publication No. 85:1989, Table 4.

Report of the Working Party on Lighting and Light-Signalling on its sixty-eighth session held in Geneva during 16-18 October 2012.
