Proceedings of the 16th International Symposium on Automotive Lighting 2025

It is a pleasure to present the Proceedings of the 16th International Symposium on Automotive Lighting (ISAL), taking place in Darmstadt, Germany, from 22–24 September 2025.

Since the first PAL conference in 1995, ISAL has grown into a leading international forum for forward-looking developments in automotive lighting. Over the years, its scope has expanded significantly, now encompassing related fields such as communication systems, sensor integration, and artificial intelligence.

The 2025 edition reflects this evolution. Contributions from around 200 authors from industry, academia, research institutes, and regulatory bodies offer deep insight into current research, trends, and future directions in the field.

This year’s symposium places particular emphasis on several key areas: the ongoing advancement of high-resolution headlamps and their integration into modern lighting functions, the increasing importance of Car2X communication and adaptive signaling made possible by modern projection technology, and the integration of camera-based lighting into advanced driver assistance systems (ADAS). Another important focus is glare and visual performance, optimizing visibility and minimizing discomfort in night-time driving. Finally, sustainability has emerged as a critical factor in the full lifecycle of lighting systems, from design through to disposal.
