Proposal to align the requirements in UN R48 with updated requirements in UN R149 (UN R48 currently only refers to a light source or light-emitting diode (LED) module(s) for dipped beam (paragraph 6.2.9.) and to light sources of the lighting units for an adaptive front-lighting system (AFS) (paragraph 6.22.9.) while the latest updates to the 01 series of UN R149 requires the communication form to indicate whether the total objective luminous flux of one or more light source(s) or light source module(s) for a dipped beam exceeds 2,000 lumens). This proposal replaces the term “LED module” with “Light source module” and modifies wording to adapt to the introduction of “matched pair” requirements for headlamps and AFS.
13. The experts from GTB proposed several amendments that aligned the requirements in UN Regulation No. 48 with the updated requirements in UN Regulation No. 149 (ECE/TRANS/WP.29/GRE/2024/3), that aligned the requirements for the passing-beam vertical inclination for off-road vehicles between the 06, 07, 08 series and the 09 series of amendments to UN Regulation No. 48 (ECE/TRANS/WP.29/GRE/2024/4) and that avoided exceeding the aggregate maximum intensity of the main-beam headlamps (ECE/TRANS/WP.29/GRE/2024/5 as replaced by GRE-90-10). GRE adopted these proposals in principle and decided to postpone their submission to WP.29 and AC.1, in order to combine them in the future with other amendment proposals to the same series of amendments.
