# Commission Implementing Decision (EU) 2020/1339 of 23 September 2020 on the approval pursuant to Regulation (EU) 2019/631 of the European Parliament and of the Council of efficient vehicle exterior lighting using light emitting diodes as an innovative technology for reducing CO2 emissions from certain light commercial vehicles in relation to the Worldwide Harmonised Light Vehicle Test Procedure (Text with EEA relevance), Division 2: TESTING CONDITIONS

Extent: E+W+S+N.I.

In the case of NOVC-HEVs, the maximum available voltage level on board shall not exceed 60 Volt.
The testing conditions shall fulfil the requirements of UN/ECE Regulations Nos 4, 6, 7, 19, 23, 38, 48, 91, 100, 112, 119 and 123. The power consumption shall be determined in accordance with point 6.1.4 of UN/ECE Regulation No 112, and points 3.2.1 and 3.2.2 of Annex 10 to that Regulation.
For the low beam adaptive front lighting system (AFS) falling within at least two of the Classes C, E, V or W as defined in Table 1 of UN/ECE Regulation No 123, the power consumption measurements shall be done at the LED intensity of each class (Pk), where k corresponds to each class specified at Table 1 as defined in UN/ECE Regulation No 123.
If it is agreed with the technical service that Class C is the representative/average LED intensity for the vehicle application, power consumption measurements shall be done in the same way as for any other exterior LED light included in the combination.
Table 1
Classes of Low beam AFS
Activation speeds shall be checked for each vehicle application in accordance with UN/ECE Regulation No 48 Section 6, Chapter 6.22, paragraphs 6.22.7.4.1 (class C), 6.22.7.4.2 (class V), 6.22.7.4.3 (class E), 6.22.7.4.4 (class W).
