Proposal 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. This document supersedes document WP.29/2013/18.

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.

Brief presentation raising question over the necessity to have triangular reflectors on the rear of large trailers and seeking greater flexibility in such rear reflectors.
