The Light That Tells You a Car Is Driving Itself

As automated vehicles move closer to everyday reality, SAE J3134 establishes a clear visual language to signal when a car is driving itself. The blue-green ADS marker lamp, now the only global lighting standard for automated driving, is already being deployed by Mercedes-Benz on Level 3 vehicles. Backed by years of research, growing public support, and international collaboration, standardized ADS lighting is emerging as a critical link between autonomous technology, road-user awareness, and trust in the next era of mobility.
