Global Automotive Relay Market Overview
The Global Automotive Relay Market was valued at USD 17.36 billion in 2023 and is projected to reach USD 24.72 billion by 2030, growing at a steady CAGR of 5.18% from 2024 to 2030. This growth is fueled by the increasing integration of electronic components, safety systems, and advanced driver assistance technologies in modern vehicles.
Automotive relays play a critical role in vehicle electrical systems, allowing a low-current circuit to control a high-current load safely and efficiently. They are widely used across passenger cars, commercial vehicles, and electric vehicles, enabling the operation of headlights, horns, anti-lock braking systems, car stereos, intermittent wipers, alarms, antennae, and more. By allowing multiple circuits to operate from a single output, relays help optimize performance, safety, and vehicle reliability.
