The expert from Germany, referring to ECE/TRANS/WP.29/GRE/2013/18, introduced a revised proposal (ECE/TRANS/WP.29/GRE/2013/62) on avoiding intentional voltage variation of a passing beam using halogen light sources. The expert from the Netherlands proposed clarifications to this proposal (GRE-70-17). The expert from IEC proposed an alternative to this proposal (GRE-70-34). The expert from France requested to simplify this proposal. The expert from Austria expressed reservations about the test procedure proposed in this proposal. The expert from Germany clarified that his proposal addressed and superseded the proposal ECE/TRANS/WP.29/GRE/2013/44 under agenda item 8 below.
