Document GRE/2014/31 proposes to introduce requirements to avoid intentional non-approved (voltage) variation of the passing and driving beam, using halogen light sources and to harmonize it with the operating voltage requirements in Regulation No. 48. This correction seeks to improve the text by replacing the “about value” for the reference luminous flux with the exact value of 13.2V and to simplify the C.o.P. procedure.
