Proposal to:

  • Align UN R48 with updated requirements in UN R149 with regard to light sources and total objective luminous flux
  • Replace the term “LED module” with “Light source module”
  • Modify wording to adapt to the introduction of “matched pair” requirements for headlamps and AFS
  • Align the requirements for off-road vehicles passing-beam vertical inclination across UN R48 series
  • Allow the projection of a pattern for predicted trajectory
  • Amend failure detection and signalisation requirements to reflect technological progress in multiple light sources.

Status: Formal WP.29 review

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.
