Proposal to render optional the fitment of front position lamps where the motorcycle is fitted with automatic headlamp switching or daytime running lamps meeting certain conditions and to add provisions regarding electrical connections and the activation of simultaneous lamps (e.g., to permit activation of rear lamps before the front lamps are activated).

Proposal to align the 03 series of amendments to UN R53 (as adopted during GRE-81: GRE/2018/50, as amended by GRE/2019/12) with the latest proposals for amendments to the 01 and 02 series (as adopted by GRE but not yet in force at the time of the present proposal:

1. Add references to UN R148, R149, and R150 (WP.29/2018/104/Rev.1 as amended by WP.29-177-07, and WP.29/2018/105), implementing the change index and amending the definitions (taking into consideration informal document GRE-80-05),
2. Align UN R53 with UN R148 regarding the inward geometric visibility requirements for rear position lamps (GRE/2018/28),
3. Clarify the use of direction indicators to show the status of the device for protection of a vehicle against unauthorised use and allow exterior courtesy lamps to be fitted on motorcycles (WP.29/2019/17 as amended by para. 107 of the session report and WP.29/2019/18 as amended by para. 108),
4. Align UN R53 with UN R48 and correct a mistake in a previous amendment process (WP.29/2018/86/Rev.1 andWP.29/2018/87/Rev.1),
5. Allow the use of different stop lamp activation methods, aligning the definition of “stop lamp” with UN R48 (GRE/2018/29), and
6. Introduce requirements for light emitting diode (LED) substitute light sources (GRE/2018/41).

Proposal for corrections to UN Regulation 65 (Special Warning Lamps) based upon Supplement 10 to the original Regulation. A recent review of the content of UN Regulation 65 has revealed some long-standing editorial errors that do not affect the technical requirements but do create confusion.

Proposal from the Simplification of Lighting Regulations informal group to delete a footnote indicator and delete characters from a figure on the standard light distribution of devices.

Proposal from the Simplification of Lighting Regulations informal group to correct a paragraph reference (‘3.3.2.2’ in place of ‘3.2.3.2’) and to insert a provision from UN R3 (para. 4.1.2.) unintentionally omitted from the original text.

Proposal to require that the vehicle manufacturer’s statement regarding frequency bands, power levels, antenna positions and installation provisions for the installation of radio frequency transmitters (RF-transmitters) be added to the information document (e.g. under item 63, Annex 2A) to facilitate conformity of production and other compliance checks.

Approach for addressing LED light sources as replacements for filament light sources via amendment of UN R37 rather than via “LED retrofits” provisions under UN R128.

Guide prepared by the GRE Substitutes/Retrofits Task Force to criteria for specifying LED substitute light source categories as equivalents for corresponding fliament light source categories.

Proposal from the Simplification of Lighting Regulations informal group to delete the luminous intensities minimum requirements for the measuring point 50L (which are not in UN R112 and therefore should not be in UN R149) from Table 8 and to correct a typo in the angular position for S100RR in Table 13. Given the importance of these corrections, this proposal is simultaneously being submitted as a formal document for consideration during the WP.29 session in November 2019.

Proposal to introduce requirements for automatic switching from DRL to headlamp(s) if the maximum luminous intensity of DRL is above 700 cd and to restore the original automatic headlamp ON (AHO) requirement for vehicles not equipped with daytime running lamps (DRL) modified by the 03 series.

Proposal to

• align UN R50 and UN R53 regarding the inward geometric visibility requirements for rear position lamps;
• to allow the use of different stop lamp activation methods for powered two-wheelers as currently applicable for four-wheelers; e.g. by the application of a retarder or a similar device.
• restore the definition of “device” (because the definition under UN R53 differs from that under UN R48)
• delete the definitions of “bend lighting”, “H plane”, “sequential activation” and “emergency stop signal” (because they are identical to the definitions in UN R48), and
• introduce requirements for light emitting diode (LED) substitute light sources.
