14. The expert from GTB recalled the outcome of the GTB study on visibility and glare (GRE-71-32) and presented a first draft of amendments to Regulation No. 48 addressing the visibility distance and glare issues (GRE-72-07). This proposal received comments by the expert from Poland (GRE-72-23-Rev.1). Various experts generally agreed that the current requirement for automatic levelling in Regulation No. 48 (2,000 lm luminous flux of the light source) should be replaced by other deciding factors for headlamp glare, such as the vehicle pitch angle, loading conditions and initial headlamp aiming. However, no consensus was reached on exact replacement criteria. The expert from UK suggested that an informal group be established to speed up the finalization of the amendment proposal. The experts from France, Germany, Italy and the Netherlands were of the view that GTB should be tasked to submit a concrete proposal to the next session of GRE. GRE invited GTB, OICA and interested Contracting Parties to organize a meeting with the aim to elaborate a revised proposal. The experts from France, Germany, Italy, Netherlands, Poland and UK expressed their interest in participating in this meeting.
