34. The expert from GTB presented a study on energy saving opportunities in automotive lighting (GRE-91-19), based on statistics from Germany. GRE experts considered that the most efficient options would be replacing traditional halogen lamps with LEDs, as well as introducing adaptive daytime running lamps (DRL) and adaptive low-beam headlamps. GRE also noted the differences between elderly and young drivers in their perception of road illumination, which should be taken into account for road safety.

34. The expert from GTB presented a report on energy saving opportunities in automotive lighting (GRE-92-06), including reduction of the daytime running lamps (DRL) – passing-beam switching threshold, both DRL and passing beam adapted to the ambient illumination. The expert from GTB pointed out that an initial proposal would be submitted to the next session. GRE took note of the report and invited GRE experts to provide feedback on the identified energy saving opportunities.
