To ask the Secretary of State for Transport, pursuant to the Answer of 16 April 2018 to Question 134899 on Motor Vehicles: Lighting, whether the review of the technical requirements been published.

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.
