Proposals for amendments to Regulations Nos. 4, 6, 7, 19, 23, 38, 48, 50, 77, 87, 91, 98, 112, 113, 119, 123 to clarify requirements for light sources in lighting and light-signalling Regulations listed in Annex 4 to UN Regulation No. 0. The proposed UN R0 on whole vehicle type approval requires submission of approval certificates for components and systems. 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). This set of proposed amendments introduces provisions for light-source approvals under the device regulations.

Proposal to

1. amend the provisions concerning the heat test requirements for Conformity of Production (CoP),
2. complete the deletion of distributed lighting systems (DLS) (light generators) from the regulations,
3. update the general CoP requirements,
4. reference the compliance requirements for installation contained in Regulations Nos. 48, 53, 72 and 86,
5. clarify the definition of “type”, with regard to manufacturer, trade names and marks,
6. introduce editorial improvements to the requirements for markings,
7. amend the formula for the dirt mixture used in testing to address an error introduced by Supplement 9 to the 01 series of amendments to UN R45,
8. remove the HV measurement point from the photometric stability requirements for the passing beam (HV measurement point remains valid for the driving beam),
9. clarify the photometric performance requirements, particular with reference to the movement of the cut-off line, during the heat test, and
10. harmonize requirements across Regulations Nos. 19, 98, 112, 113 and 123.
