Proposal from the Simplification of Lighting Regulations informal group to delete the luminous intensities minimum requirements for the measuring point 50L (which are not in UN R112 and therefore should not be in UN R149) from Table 8 and to correct a typo in the angular position for S100RR in Table 13. Given its urgency, the proposal has been submitted in parallel for GRE consideration (GRE-82-02).

Proposal to reintroduce the run-up provisions for high-intensity discharge (HID) headlamps that were unintentionally omitted from the original text of UN R149.
