Working Party on Lighting and Light-signalling | Session 75 | 5-8 Apr 2016

13. The expert from GTB informed GRE about activities of the GTB Working Group Light Sources and its plans to extend Regulation No. 128 to light sources for forward lighting applications covered by Regulations Nos. 19, 98, 112, 113 and 123 (GRE-75-14). Proposals for amendments to Regulation No. 128 would include performance-based requirements for visibility and glare as well as introduce thermal grades for light emitting diodes (LED) light sources which could be subject to heat from a combustion engine. Forward lighting Regulations Nos. 19, 98, 112, 113 and 123 would need to be amended to accept LEDs of Regulation No. 128 and their thermal grades. GRE took note that amendment proposals would be submitted to the next session. A number of experts posed questions on the thermal grade concept proposed by GTB and were of the view that a detailed clarification should be included in the justification part of future documents.

59. GRE noted that the status reports of the GTB Working Groups were presented under agenda item 4 (paras. 13 and 14 above).
