UN Regulation No. 48
Installation of Lighting and Lighting-Signalling Equipment

Uniform Provisions Concerning the Approval of Vehicles with regard to the Installation of Lighting and Light-signalling Devices

Regulation No. 48 establishes minimum requirements for lighting equipment towards ensuring satisfactory levels of traffic safety, including such areas as adequate forward illumination, limits on headlamp glare, luminosity of signalling lamps, etc. The regulations considers the installation and functioning of lighting equipment as a whole to ensure compatible performance across all types of equipment and devices (headlamps, signalling lamps, markers lamps, etc.).

1 Dec 2017 1 Dec 2017 | EU’s car emission goals for 2030 stir up ‘tech neutrality’ debate Worldwide Harmonized Light Vehicles Test Procedure

This GTR prescribes a test cycle and test procedures to measure the emissions (including off-cycle) and fuel efficiency of light-duty vehicles. The GTR was adopted at the March 2014 session of the World Forum.

A supplemental "phase 1b" is underway to refine certain elements of the initial regulation. WP.29/AC.3 expects to consider a proposal for Amend. 1 to UN GTR No. 15 in November 2016 as result of Phase 1b activities.

A second phase is expected to address low ambient temperature, high altitude test procedures, and possibly durability and conformity issues.

A third phase would eventually include the addition of reference fuels, correlation across existing regional/national cycles, and introduction of emissions limits.

The latest draft version of the amended GTR is regularly updated by the WLTP informal working group.

The regulation is also supplemented by a gearshift calculation tool.
