Based on LS-1691, this document defines specifications for HB3 LED light sources. LED light sources shall not exceed the specified envelope, function in either voltage polarity, and be rotated in the measuring holder until the reference lug contacts the holder plane. Essential electrical and photometric characteristics include rated values at 12V and 13.2V, with minimum luminous flux of 2000 lm and cap temperature limits. Luminous flux measured at elevated ambient air temperature shall be at least 75% of objective luminous flux. Screen projection requirements specify box system proportions for light emitting areas and contrast limits. Normalized luminous intensity distribution shall comply with specified limits in defined C-planes when measured at test voltage.
This document defines category HIR2 LED light source specifications. The LED light source shall not exceed the envelope indicated in Figure 2, be concentric to the reference axis, and function in either voltage polarity. Essential characteristics include rated values at 12 volts DC of 26 watts power and 2000 lm minimum luminous flux. Cap temperature shall not exceed 63°C at test voltage or 100°C at elevated ambient air temperature. Luminous flux measured at elevated ambient air temperature shall be at least 75% of objective luminous flux. Light emitted shall be white. The contrast proportion of luminous flux shall be 100 minimum. Normalized luminous intensity distribution shall comply with specified limits in C-planes.
This document specifies requirements for category H10 LED light sources with PY20d caps. The light source shall not exceed the outlined envelope and shall function in either voltage polarity. Essential characteristics include rated values of 12 volts and 21 watts, with luminous flux of 1500 lm minimum at test voltage. The luminous flux measured at elevated ambient air temperature shall be at least 75% of objective luminous flux. Screen projection requirements define light-emitting area positioning using box systems. Normalized luminous intensity distribution requirements are specified in C-planes with defined test points and minimum/maximum intensity values in cd/klm.
This document defines essential dimensions, electrical characteristics, and photometrical requirements for LED light source category H9. The LED light source shall not exceed the specified envelope and shall function in either voltage polarity. Rated values include 26 watts at 12 volts and 26 watts minimum at 13.2 volts, with minimum luminous flux of 2000 lm and cap temperature not exceeding 100°C. The luminous flux measured at elevated ambient air temperature shall be at least 75% of objective luminous flux. The document specifies screen projection requirements, contrast requirements, and normalized luminous intensity distribution requirements across defined C-planes and test points.
Revision of TFSR-26-03 addresses H9 LEDr flux considerations and dual-voltage specification. The document proposes applying a single specification for H9 LEDr: 1875 lm ±10% @13.2V, representing a compromise between high-beam and low-beam applications. This luminous flux level is not critical, as high-beam measurements with H9 filament bulbs exceed legal minimums by more than 10%, and low-beam safety margins remain acceptable with limited flux increases. Additionally, a black-top limit of 50 cd/klm at control point zero is proposed for bulbs without black-top specification, and LEA sub-zone specifications (B1, B2, B3) for high-beam categories should be optimized to support beam performance.
Proposal to revise the terms of reference and rules of procedures for the Informal Working Group on Advanced Emergency Braking Systems. The IWG shall review current regulatory actions and data on Automated Emergency Braking Systems and provide recommendations on future regulatory actions including revisions to UN Regulation No. 152. The IWG shall examine current AEBS regulations worldwide, assess accident situations for passenger vehicles, draft state-of-the-art performance requirements for collision scenarios involving pedestrians at night, investigate regulatory improvements to performance requirements, and investigate feasibility to include updated requirements to avoid false activation of AEBS for light vehicles. The IWG shall deliver complete regulatory text for AEBS for passenger vehicle requirements as revision of UN Regulation No. 152 for the September 2028 session of GRVA at the latest.
The AEBS IWG held its initial meeting virtually on 22 April with about 50 attendees. Co-Chairs are Germany and Japan; Co-Secretaries are CLEPA and SAE. The IWG is requesting minor changes to its Terms of Reference. A schedule of meetings is planned from September 2026 through September 2028, including informal meetings for input from contracting parties and industry, discussion of requirements for speed reduction in nominal conditions, and investigation of false positives, with a draft regulation document planned for January 2028 and formal submission planned for September 2028.
The document requests guidance on the legal basis for provisions within UN Regulations extending beyond the End-of-Production date and which authority such provisions address. Examples include UN R171 requirements for manufacturers to demonstrate safety management systems to the Type Approval Authority every three years and report annually on Driven Coded Auxiliary System operation until production is discontinued, and UN R155 requirements for Cyber Security Management Systems to apply to the post-production phase when vehicles remain operational but are no longer produced. The document poses an additional question regarding vehicle safety when manufacturers cease operations and cannot fulfill post-deployment safety provisions.
