More than 500 persons gathered in Paris La Villette on 16-17 October for SIA VISION, the biennial symposium organized by SIA (Société des Ingénieurs Automobiles, the French SAE), including 41 exhibitors and more than 120 different companies, to talk about lighting and ADAS.
Gilles Vidal, head of Renault design, 10 years after Laurens van den Acker in 2014, presented his design vision and the importance of lighting:
- What is a good design?
- Less but better as was saying Dieter Rams
- Good design = Progress by Aesthetic, Function, Innovation, and Emotion
- “Just right” is not the same for every brand
- With that extra thing distinguishing it, for instance Lit logo, grille, charge indicator,..

Makers like Renault, BMW, and Stellantis presented their latest products. Illuminated grilles from BMW and Renault are below 18 Watts, and BMW announced a luminance of 2,000 cd/m2.
