Proposal to refine the requirements for lamps equipped with several light sources, including in systems fitted with an operating tell-tale that indicates the failure of any one of these light sources. In the case of failure of any one light source in a single lamp containing more than one light source, either the light intensity must comply with the minimum intensity required in the table of standard light distribution in space or, for lamps used in systems where a tell-tale indicates the failure of any one of the light sources, the light intensity in the axis of reference must be at least 50 per cent of the minimum intensity required.
