The International Organization for Standardization (ISO) has officially commenced the standardization process for the Open System Protocol (OSP), a communication platform for automotive lighting systems originally proposed by ams OSRAM.
Context
On February 17, 2026, the International Organization for Standardization (ISO) officially launched the process to transform ams OSRAM’s Open System Protocol (OSP) into a global automotive standard. The initiative, managed by Technical Committee TC 22, aims to establish ISO 26341-1 as a universal communication protocol for dynamic lighting and intelligent vehicle networks. This transition from a proprietary solution to an open industry standard reflects the increasing demand for interoperable technologies within Software-Defined Vehicles (SDVs) and modern zone-based electrical architectures.
Developed to solve the 'last-mile' connectivity challenge, OSP allows a single microcontroller to manage up to 1,000 intelligent nodes, including RGB LEDs, sensors, and actuators. The protocol is already utilized in series production via components like the OSIRE E3731i intelligent LED and is supported by a growing ecosystem of microcontroller and IC manufacturers. By providing a license-free, high-speed 2.4 Mbit/s interface, ams OSRAM positions OSP as a critical building block for future cabin experiences and safety-related lighting functions.
