UN R128: Proposal for Supplement 10
Document WP.29/2020/31
30 December 2019

Proposal to insert a minimum luminance gradient as an alternative criteria. The current text requires a certain “asymmetry” of the Light Emitting Area (LEA) in order to ensure a “minimum worst-case gradient”; however, this requirement has been deemed too design-restrictive.

20. The expert from GTB proposed amendments to light source categories L1A/6 and L1B/6 in the Consolidated Resolution on the common specification of light source categories (R.E.5), together with an associated amendment to UN Regulation No. 128 (ECE/TRANS/WP.29/GRE/2019/15, ECE/TRANS/WP.29/GRE/2019/16). GRE adopted both proposals and requested the secretariat to submit them, as appropriate, to WP.29 and AC.1 for consideration at their March 2020 sessions as draft amendment 5 to R.E.5. and Supplement 10 to the original version of UN Regulation No. 128.
