Proposal to introduce a new category: D8R.

Proposal to introduce a new category, ‘D9S’.

Proposal to add a new paragraph 3.6.2.4. to UN R99 in order to clarify how the run-up of dual-level high-intensity discharge (HID) light sources, as e.g. D9S, should be tested during type approval. In addition, the proposal renumbers the part of 3.6.2.2. that applies to gas-discharge light sources containing black stripes as 3.6.2.3. to make the distinction with gas-discharge light sources not containing black stripes.

The regulation of lighting includes individual regulations for specific lighting devices (headlamps, direction indicators, etc.), for light source (filament, gas, LED), and for installation (UN R48). The proposed UN R0 on the type approval of whole vehicles requires submission of approval certificates for components and systems to be included within the whole vehicle approval. Vehicle manufacturers work directly with UN R48 approvals, but lamp and device approvals are generally handled by lighting suppliers. UN R48 includes provisions for listing approvals of lighting units, but not for approvals of light sources (presently UN R37, R99, and R128). In order to avoid excessive administrative burdens, GTB proposes that the regulations covering light units include provisions to confirm their approval under the applicable light source regulations such that UN R48 approvals would represent approval of the vehicle lighting systems under both device regulations and light-source regulations.
