Proposal to correct the terminology in paragraph 5.7.2.1. for consistency across all requirements and to clarify the language in paragraphs 6.2.9., 6.3.6.1.2.1. and 6.3.6.1.2.2. to promote the correct application of the 2,000-lumen limit.

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).
