Submission by the Working Party “Brussels 1952” (GTB) to clearly define the conditions under which voltage control gear may be used in conjunction with filament light sources.

Proposal prepared by the International Motor Vehicles Association (IMMA) and supported by the Working Party “Brussels 1952” (GTB) to introduce bend lighting for motorcycles.

Proposal to ensure that the signal requirements to indicate the activation of a failure tell-tale are not constrained to a particular type of light source. The current wording of UN R6 relates only to filament lamps; other light sources should be treated identically to avoid design restriction.

Proposal to align the cut-off requirements of UN R19 with UN R98 and R112 such that the cut-off quality (sharpness (G value) and linearity of the cut-off) are only assessed when the vertical adjustment cannot be performed repeatedly to the required position due to an unclear cut-off.

Proposal to amend the title of UN R31 by inserting “Halogen” and using the abbreviation “HSB” in order to distiguish the regulation from UN R5. In its justification, GTB also raises the “freezing” of both these regulations as they relate to outdated technologies for future consideration.

Proposal from the Working Party “Brussels 1952” (GTB) to introduce a new category of amber dual-filament light sources PY21/5W into UN R37.

Proposal from the Working Party “Brussels 1952” (GTB) to clarify color measurement requirements.

Proposal from the Working Party “Brussels 1952” (GTB) to update provisions on heat resistance tests.

Proposal from the Working Party “Brussels 1952” (GTB) to amend the requirements on light-source failures (paragraph 7.4. (“n-1 rule”)) in order to permit the introduction of new cost-efficient designs for daytime running lamps.

Proposal from the Working Party “Brussels 1952” (GTB) to revise paragraph 5.23 to clarify the requirements on the replacement of light sources approved according to UN R37.
