This document presents the draft agenda for the 8th meeting of the GRE Task Force on Glare Prevention, scheduled for 9 June 2026 at CLEPA Headquarters in Brussels. The agenda includes welcome remarks, adoption of the agenda, approval of the previous meeting report, feedback from GRE-94, and status updates on HWT on PTI, ADB/AFS, and Regulation 48. Discussion topics cover horizontal adjustment of passing- and driving-beam and AFS-ADB, vehicle preparation for passing-beam measurement, and updates from the GTB Task Force Glare Control. Future meetings are scheduled for Tokyo in September 2026 and Brussels in December 2026.

The Homework Team on ADB/AFS status report to the GRE Taskforce “Glare prevention” documenting timeline activities from February to June 2026, including seven HWT meetings and three TFGP sessions. The team listed system descriptions, benefits, disadvantages, conducted literature review, identified elements causing glare, negative effects to ADB/AFS performance, and improvable requirements. The team drafted recommendations addressing enforcement of headlamp cleaning, reduction of 2000lm limit, manual override requirements, improved detection and camera specifications, motorway ADB usage, cleaning systems, beam pattern dimming, and adaptive beam patterns for various driving conditions.

The Homework Team on Adaptive Driving Beam/Adaptive Front-lighting Systems prepared a status report identifying elements causing glare in activated ADB/AFS systems, including wet road conditions, external objects obstructing sensors, soiled headlamps, camera positioning, and detection limitations. The report examined literature and expert inputs to determine negative performance effects and recommend improvements such as enhanced detection capabilities, stricter cleaning requirements, increased safety margins, predictive beam adjustment, mandatory motorway ADB usage, and driver instruction on manual override functions. Knowledge gaps and potential research needs were identified for consideration in draft recommendations to the Taskforce on Glare Prevention.

TFGP-08-06 (Rev. of TFGP-07-08) presents draft recommendations for GRE on glare prevention. The recommendations include:

• Consider dynamic auto-levelling for all vehicles,
• lower maximum installation height of headlamps,
• reduce the 2000lm limit for headlamp cleaning devices and make cleaning mandatory on AFS/ADB lamps,
• improve ADB requirements for latency and vehicle detection,
• introduce Motorway ADB requirements,
• define adaptive cut-off lines,
• address PTI coordination with type approval requirements,
• provide driver instructions for ADB manual override,
• improve headlamp cleaning enforcement and driver awareness,
• investigate aiming differences between production line and PTI,
• address alignment degradation within the first 10,000 km.
