Proposal for new headlamp aiming tolerances from the informal group on Visibility, Glare, and Levelling.

Revised proposal, superseding document GRE/2017/11, from the Simplification of Lighting Regulations informal group to introduce references to the three new simplified Regulations (Light-Signalling Devices (LSD), Road Illumination Devices (RID) and Retro-Reflective Devices (RRD)) into Regulation No. 48.

Proposal to introduce references to the new lighting device regulations being finalized under the Simplification of Lighting Regulations program. This document is provided for information with the references to the future device regulations in brackets.

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.
