28. The expert from IEC introduced GRE-71-13 proposing alternatives to ECE/TRANS/WP.29/GRE/2013/62 on electronic light source control gear:
(a) Restricting the voltage range for (halogen) filament light sources, to avoid (semi-)permanent too low or too high luminous intensity of the headlamp and subsequent shorter lifetime of the filament light source and;
(b) Inserting a lower voltage limit and verifying that the headlamp performance, in terms of luminous intensity, under the normal operating conditions of the vehicle’s electrical system is still compliant with the requirements of UN Regulation No. 112.
29. A number of experts delivered remarks on this document. GRE invited other experts to transmit their comments, if any, to IEC and decided to revert to this issue on the basis of a revised document to be prepared by IEC.

Document GRE/2013/62 concerning electronic light source control gear proposed to introduce requirements to avoid intentional non-approved (voltage) variation of the principal passing beam using halogen light sources and to harmonize them with the operating voltage requirements in UN Regulation No. 48. The objective of this proposal is to restrict the voltage at headlamps equipped with (halogen) filament lamp light sources in order to avoid excessively high or low (semi-) permanent luminous intensity of the headlamp and consequently shorter lifetime of the halogen light source. This submission takes into account the positions presented in documents GRE/2013/44, GRE/2013/62, GRE-70-17, and GRE-70-34.
