The United Nations Economic Commission for Europe (UNECE) informal working group (IWG) on Visibility, Glare and Levelling has reported back to the Working Party on Lighting and Light Signalling. The documents and reports for these groups are publicly available on the UNECE website: http://www.unece.org/trans/main/welcwp29.html. The IWG proposed to revise the headlamp aiming criteria for new vehicles but the working party did not consider their proposal to be sufficiently developed for inclusion in the regulations. As a result, it was decided that this work will continue as part of a broader review of vehicle lighting regulations.
