In addition to ECE approvals, there are additional certifications and markings applied to vehicle lighting and other technical products in Europe and some other regions. Here are some of the most well-known certifications besides ECE approvals, such as the D-mark, covering various aspects of quality, safety, and environmental performance:

1. D-mark – German Certification 
   The D-mark (Deutsches Prüfzeichen) is a German certification primarily applicable to products that meet German standards for quality and safety. For vehicle lighting, this often means that products meet stringent requirements in terms of performance and reliability. This mark is voluntary but frequently requested by consumers and professionals due to Germany's strict standards.
2. CE Marking – Conformité Européenne
   The CE marking is a mandatory label for products sold in the European market, indicating compliance with EU directives on safety, health, and environmental protection. For vehicle lighting, this means it meets fundamental safety standards, but the CE marking does not test specific vehicle lighting requirements as ECE markings do.
3. E-mark – European ECE Approvals
   As previously discussed, E-markings are part of ECE standards, indicating that vehicle lighting has been approved according to European standards. The E-mark is often confused with the D-mark but covers multiple European countries and is specifically focused on vehicle components.
4. R-Label – Dutch Mark for Reflection 
   The R-label is often applied to reflectors and retroreflective materials, indicating compliance with Dutch requirements for visibility and reflection, commonly needed for vehicles and bicycles.
5. UL Mark – Underwriters Laboratories (USA)
   The UL mark is a certification widely used in North America, primarily focused on electrical safety in electronic products, and can sometimes apply to lighting exported to the North American market. UL tests for criteria such as electrical safety, durability, and fire safety.
6. SAE Marking – Society of Automotive Engineers (USA)
   SAE markings are often used in the United States and Canada, encompassing specific standards for vehicle lighting and other components. Although SAE is not required for European markets, it may apply to vehicles sold in North America.
7. RoHS Mark – Restriction of Hazardous Substances
   RoHS is a European directive limiting the amount of hazardous substances like lead and mercury in electronic devices. Although RoHS is not specifically aimed at vehicle lighting, much modern lighting meets these requirements to ensure environmental friendliness.​
8. IP Rating – Ingress Protection Marking 
   The IP rating is a classification system indicating how well a device is protected against water and dust. For vehicle lighting, a high IP rating is essential to ensure that the lamp withstands rain, dirt, and other environmental factors..​.
9. TÜV Certification – Technischer Überwachungsverein (Germany)
   TÜV is a German certification body testing a wide range of products, including vehicle lighting. TÜV certification indicates that a product has been thoroughly tested for safety and reliability, meeting German standards. The TÜV mark is recognized and trusted worldwide.
10. KEMA Mark – Certification Institute for Electrical Materials (Netherlands) 
    KEMA is a Dutch mark mainly applied to electrical equipment. Although not specifically for vehicle lighting, it can be relevant to the electrical components of the lighting system.

These additional certifications and markings can help ensure the quality and safety of vehicle lighting, especially concerning electrical safety, durability, and environmental friendliness, alongside ECE requirements.
