GB/T 32482-2024 in English

The National Standardization Administration Committee has released the standard GB/T 32482-2024, which specifies requirements for color sorting of white light-emitting diodes (LEDs) used in motor vehicles. This standard is set to take effect on July 1, 2025, and aims to ensure uniformity and quality across the automotive lighting industry by establishing criteria for assessing and categorizing the chromatic properties of LED components employed in vehicle headlights, taillights, and other critical illumination systems.

The document outlines detailed methods for evaluating LED color consistency, including parameters such as correlated color temperature (CCT), color rendering index (CRI), and spectral purity. It provides guidelines for manufacturers to test and classify LEDs according to specific standards, ensuring that vehicles equipped with these components meet safety and performance benchmarks.

In addition, the standard emphasizes the importance of ongoing monitoring and quality control throughout the supply chain, from LED production to vehicle assembly. By adopting this new norm, automotive suppliers and original equipment manufacturers (OEMs) can enhance product reliability, reduce warranty claims related to lighting defects, and contribute to a safer driving environment through improved visibility.
