Mr. de Visser introduced a revised light sources package, updated following the 74th GRE session. This comprehensive package includes the draft simplified regulations (namely R-37, R-99, R-128 and an extensive justification), the draft resolution on the common specification of light source categories and additional documents to better understand the huge work done and the modifications made to the texts.

During the discussion of the draft resolution document (namely “SLR-07-04 – rev of GRE-2015-28 – draft resolution.docx”), the meeting agreed to move Par. 2.2.1 between Par. 3 and 3.1 and to delete Par. 2.2 as follows:
“ 2.2. General specifications
2.2.1. Luminous flux values in the light source category sheets concern white light unless otherwise specified in these sheets.
3. Light source categories and their use
Luminous flux values in the light source category sheets concern white light unless otherwise specified in these sheets
3.1. Filament light sources
… … …”

During the discussion of the draft simplified regulations, the meeting agreed to indicate the definitions of filament, gas-discharge and LED light sources in the resolution document only. Regulations will refer to them like for the R.E.3. Mr. de Visser will produce a final package for submission to the 75th GRE session (this is now available as document SLR-07-11).

This item was not discussed.

Mr. de Visser introduced document SLR-08-03 pointing out that Part A is waiting for lamp Regulations to be changed and accordingly, he will update light source regulations. Moreover he reported that Part B is already implemented for signalling lamps and will be done later for forward lighting regulations.

The participants quickly reviewed each item of Part B. The following is a list of the most significant exchanges:

Mr. Genone expressed some concerns to move the use restrictions in the Resolution because, in his opinion, the Resolution for Light Sources should only be a catalogue while the use restrictions should remain in the Regulations. Mr. Pichon shared the same opinion.

Mr. de Visser explained that “use restrictions” are an option in the lamp regulations and do not change the requirements to all lamps in a lamp regulation. He recalled that his explanation was well understood in WP.29 with his past presentation in WP.29 session in November 2015, where WP.29 reconfirmed the light sources simplification approach. Therefore he strongly recommended not to change direction at this point as such a change would make the simplification by a Resolution ineffective.

It was agreed not to change the current direction but Mr. de Visser was asked to clearly explain this issue in his presentation at GRE-75 to avoid a long discussion.

With regards to the deletion of 6V Light Sources, Mr. de Visser suggested to delete the 6V systems as those light sources are no longer allowed for new type approved lamps. Mr. Pichon observed that such a deletion would be a change of requirements and therefore it should be modified during the step 2.

It was agreed to address the deletion of the 6V systems during the 2nd step of the simplification work.
