The E-mark certification for car lights is a mandatory certification for car light products based on regulations developed by the United Nations Economic Commission for Europe (ECE). The E-mark certification aims to ensure that vehicle lighting products comply with the safety, environmental, and performance requirements of Europe and other countries that recognize this regulation. The following is a detailed explanation of the E-mark certification for car lights:

 

Scope of Application
E-mark certification applies to various types of vehicle lights, including:

Headlights: low beam, high beam, front fog lights, etc.

Rear headlights: taillights, brake lights, rear fog lights, reverse lights, etc.

Turn signal: front turn signal, rear turn signal, side turn signal, etc.

Position lights: front position lights, rear position lights, etc.

Other car lights: license plate lights, interior lighting, etc.

 

Certification regulations
The specific regulations for E-mark certification of car lights depend on the type and function of the car lights, and common regulations include:

Headlights:

ECE R112: Used for LED headlights.

ECE R113: Used for halogen headlights.

ECE R98: Used for gas discharge lamps (such as xenon lamps).

Rear headlight:

ECE R7: Used for front and rear position lights, brake lights, turn signals, etc.

ECE R38: Used for rear fog lights.

ECE R77: Used for reversing lights.

Other car lights:

ECE R4: Used for license plate lights.

ECE R87: Used for daytime running lights (DRL).

ECE R119: Used for turn signal lights.

 

Certification requirements
The requirements of E-mark certification for car lights mainly include the following aspects:

Optical performance:

The brightness, light type, and color of the car lights must comply with regulatory requirements.

For example, the light pattern of the headlights needs to ensure sufficient illumination range and not produce glare.

Mechanical properties:

The structural design of car lights must meet requirements such as waterproof, dustproof, and anti vibration.

The installation method of the car lights needs to ensure stability and adjustability.

Electrical performance:

The electrical system of the car lights must meet the requirements of voltage, current, power, etc.

For example, the driving circuit of LED headlights needs to meet electromagnetic compatibility (EMC) requirements.

Environmental adaptability:

The car lights need to work normally in environments such as high temperature, low temperature, and humid heat.

For example, car lights need to undergo high and low temperature cycling tests as well as humidity and heat tests.

 

Durability:

The headlights need to maintain stable performance even after prolonged use.

For example, car lights need to undergo lifespan testing and vibration testing.

certification process
Product Design:

Design car lights according to relevant regulations to ensure compliance with optical, mechanical, electrical, and other requirements.

Pre testing:

Conduct pre testing before formal certification to ensure that the product meets regulatory requirements.

Formal testing:

Conduct a complete set of tests in an accredited laboratory, including optical performance, mechanical performance, electrical performance, etc.

Document preparation:

Prepare technical documents, including product specifications, test reports, circuit diagrams, user manuals, etc.

Application for certification:

Submit an application to the certification body and provide relevant documents.

Factory audit:

Certification bodies conduct audits of production factories to ensure that the production process meets quality control requirements.

Obtain certificate:

After passing the audit, obtain the E-mark certification certificate, and the product can be affixed with the "E-mark" logo.

 

E-mark logo
Car lamp products certified by E-mark can be affixed with the "E-mark" logo.

The logo consists of the letter "E" inside a circle and a number, where the number represents the country code issuing the certificate (e.g. E1 represents Germany, E4 represents the Netherlands).

 

importance
Market Access:

E-mark certification is a mandatory requirement for automotive lighting products to enter the European market.

safety

Ensure that the headlights provide reliable illumination during vehicle operation to ensure driving safety.

competitive power:

Certified products are more likely to gain customer trust and enhance market competitiveness.

 

summary
The E-mark certification of car lights is an important certification to ensure that car light products comply with European and other national safety, environmental, and performance requirements that recognize this regulation. Manufacturers should fully consider relevant regulatory requirements during product design and development to ensure smooth certification and entry into the market. Automotive lighting products certified by E-mark not only meet regulatory requirements, but also enhance brand image and market competitiveness.
