Standard GB 4785-2019 – CCC Certification for Headlights

5. May 2022

The use of External Lighting and Light-Signaling Devices for Motor Vehicles and their Trailers has been controlled by official regulations in China since 1984. In order to import and sell these products in the country, a valid CCC certification is mandatory by law.

For almost 15 years, GB4785-2007 has been the valid national test standard (Guobiao Standard) for this product group in China. However, it was replaced by the new version GB4785-2019 on July 1, 2020. The new standard includes important changes that may affect the certified manufacturers, the vehicle OEMs, and suppliers.

In some cases, such regulations for vehicles only come into force from a certain registration year.



The most important adjustments include changes of definitions within the certification scope. This applies to interdependent lamp systems, maneuvering lamps, cornering lamps, conspicuity markings, rear-end collision alert signals, adaptive front lighting systems and others. The term of equivalent lamps has meanwhile been completely removed from the standard. Certified manufactures, whose products were before grouped under one of the product categories listed above, now need to verify the validity of their classification.

A further update relates to the testing requirements of specific products, especially of headlamps. Moreover, the calculation of light emitting, illuminating, and apparent surface areas was modified, which must be implemented in new and existing application documents.

Last, the new standard explicitly allows the use of lamps and other exterior lighting and light-signaling devices which are not covered by its regulations under certain conditions in the static state of the vehicle.

The GB standards and product-specific Implementation Rules in China are subject to regular modifications by the authorities. Updates are usually not publicly announced, so it is the responsibility for manufacturers to closely follow updates and adjustments before the deadlines. If the new test standards or new regulations are not met by the given deadline severe consequences including problems at customs and/or cancelations of certificates may happen without prior warning.
