Terms of reference adopted during the October 2018 GRE session.

European Commission and Japan joint position on the Task Force on Headlamp Switching (TFHS) proposal to introduce updated requirements for headlamps and daytime running lamps.

Proposal to delete the draft provisions that would limit the reduction of luminous intensity levels to conditions where the vehicle speed is below 20 km/h and the distance to the following vehicle(s) is less than 20 m.

Proposal to improve the text regarding LED substitute light sources. ( “If a LED substitute light source is approved to be used in a lamp installed on a vehicle type, a declaration shall be made in the communication form.”)

Proposal to enable approval of side-marker and position lamps with regard to switching requirements when mutually incorporated. Vehicles include designs where lamps wrap around vehicle corners. In cases where optional side-marker lamps are grouped with a position lamp that is reciprocally incorporated with the direction indicator, it should be possible to switch off the side-marker lamp (as can be done with the position lamp) in order to improve conspicuity of the direction indicator.

The proposal also defines specifications for the design and operation of external status indicators for Vehicle Alarm Systems (VAS), Alarm Systems (AS) and immobilizers under UN R48 pursuant to provisions of UN R97 and R116.

The proposal also corrects and clarifies the following:

• para. 5.7.2.1. editorial alignment of text with current terminology
• replace undefined “effective outlet” terminology with defined “apparent surface” reference
• reintroduction of missing reference to “transverse plane” in paras. 5.10.1. and 5.10.2.
• para. 6.2.9. and related subsequent paragraphs to clarify the application of the 2000 lumen criteria
• para. 6.26.9.2. to correct a cross-reference with UN R23
• measurement of the minimum height in relation to the ground for dipped beam headlamps (para. 5.8.2).

Proposal to improve the document GRE/2018/11 (GRE-79-31) and to introduce in R48-06 new minimum installation requirements for type approved lighting and light-signalling devices and to improve the transitional provisions for Regulations Nos. 3, 4, 6, 7, 19, 23, 27, 38, 50, 69, 70, 77, 87, 91, 98, 104, 112, 113, 119 and 123. Proposal for new minimum installation requirements for type approved lighting and light-signalling devices in R48-06. Proposal to clarify which devices may be installed on the vehicles in line with the applicable requirements as amended by the new UN Regulations on light-signalling devices, road illumination devices, and retro-reflecting devices.

Proposal to define specifications for the design and operation of external status indicators for Vehicle Alarm Systems (VAS), Alarm Systems (AS) and immobilizers under UN R48 pursuant to provisions of UN R97 and R116.

Because the new lighting device regulations (LSD, RRD, and RID) each cover multiple lighting functions (e.g. direction indicators, marker lamps, DRL in the LSD regulation), the potential exists for a change in stringency to impact some, but not all functions within the scope of each regulation. The change index is proposed in order to track the impact on each function and so restrict the need for new type approvals only to those functions impacted by a change in stringency.

Comments on the proposal from Germany and Italy for the 07 series of amendments to UN R48 and for Supplement 20 to UN R87.

Discussion document from the Netherlands and Italy to serve presenting potential new requirements for headlamp levelling, in particular regarding the vertical inclination in relation to the dipped-beam headlamp mounting height.
