UN R48 — 07 series of amendments

Paragraph 2.7.6. now gives "Definitions with regard to switching and activation". "Switch ON" means to manually or automatically operate an illuminating or signalling function to effectively emit light (para. 2.7.6.1.). "Switch OFF" means to do so to stop emitting light; both apply irrespective of whether the function is operating correctly or not. "Activate" and "Deactivate" mean to manually or automatically enable or disable such a function, irrespective of whether light is emitted or not. In many paragraphs, "activated", "lit" and "switched on" now read "switched ON", and "switched off" now reads "switched OFF". Many paragraphs also say "propulsion system" instead of "engine", for example paragraph 6.7.7.2.

The emergency stop signal is now mandatory on motor vehicles and optional on trailers. Before, the entry read "Optional". Paragraphs 6.23.7.3. to 6.23.7.3.2. now say "switched ON" and "switched OFF" instead of "activated" and "deactivated". Paragraphs 6.23.7.3.1. and 6.23.7.3.2. now say "UN Regulations Nos. 13 and 13-H" instead of "Regulations Nos. 13 and 13-H".

Under paragraph 5.11., the lamps it lists can only be switched ON and OFF simultaneously. Paragraph 5.11.1. now says this requirement does not apply while one or more of four listed conditions exist. New condition (c) is "Daytime running lamps are switched ON". Paragraph 5.11.1.3., "When light-signalling system operates according to paragraph 6.19.7.4.", is deleted. The rule that a direction indicator "capable of being activated in different modes (static or sequential)" must not switch between modes once activated is deleted. The rule on the mode of two optional lamps (category 2a or 2b) on vehicles in categories M2, M3, N2 and N3 is also deleted.

In paragraphs 6.4.7.2., 6.20.7.2. and 6.26.7., the speed limits of 10 km/h are now 15 km/h. Devices fitted on the side of the vehicle (para. 6.4.7.2.) may be switched ON for slow forward manoeuvres up to 15 km/h, under listed conditions. One condition is that they are switched OFF automatically if the forward speed exceeds 15 km/h, regardless of the separate control position. Cornering lamps switched ON with the reversing lamp must be switched OFF when it is switched OFF, or when the forward speed exceeds 15 km/h. Manoeuvring lamps must be switched ON automatically for slow manoeuvres up to 15 km/h, if one of the listed conditions is fulfilled. They must be switched OFF automatically if the forward speed exceeds 15 km/h, and remain OFF until the switch ON conditions are met again.

Except for intermittent luminous warnings at short intervals, main-beam headlamps may now be switched ON only in two cases (para. 6.1.7.1.). These are when the dipped-beam headlamps are manually activated, or when the conditions for automatic switching ON of dipped-beam headlamps exist. The main-beam headlamps must be switched OFF automatically when the dipped-beam headlamps are manually deactivated or those conditions cease to exist. Daytime running lamps may be switched OFF manually, provided they switch ON automatically above 15 km/h or after more than 100 m (para. 6.19.7.2.). The proviso also requires that they remain ON until deliberately switched OFF again. Before, the speed in this proviso was 10 km/h, and manual switching OFF was allowed "when the vehicle speed does not exceed 10 km/h".

New paragraph 2.10.11. defines the "V plane". It is a vertical plane parallel to the median longitudinal plane of the vehicle and containing the center of reference of the lamp. Former paragraphs 2.10.11. to 2.10.17. are renumbered as 2.10.12. to 2.10.18. Paragraph 2.3.11.2., the trailer part of the "Park condition of a vehicle" definition, is deleted. The sentence "Before making any measurement wait until the vehicle has assumed its final attitude with the engine running." is deleted. The 2,000 lumen conditions for headlamp cleaning devices and for vertical inclination no longer say "for each headlamp".

The first two digits of the approval number are now 07 (para. 4.2.), and the Annex 2 approval mark examples refer to the 07 series. From 6 July 2022, Contracting Parties applying this Regulation need not accept approvals to the preceding series first issued after 5 July 2022 (para. 12.6.2.). Until 6 July 2024, they must accept approvals to the preceding series and extensions thereof, first issued before 6 July 2022 (para. 12.6.3.). From 7 July 2024, they are not obliged to accept approvals, including any extensions, to the preceding series without emergency stop signal installed (para. 12.6.4.). Notwithstanding paragraph 12.6.4., they must continue to accept approvals to the preceding series for vehicle types not affected by the 07 series changes (para. 12.6.6.). WP.29 amended paragraphs 12.6.2. to 12.6.4. when it recommended the text to AC.1; the text GRE adopted had 1 June 2022 and 1 June 2024.
