When comparing professional warning lights, ECE R65 Class 1 and Class 2 are often presented as if one were simply a higher-grade version of the other. The actual distinction is more specific: under UN Regulation No. 65, Class 1 warning lamps have one approved level of luminous intensity, while Class 2 warning lamps have two.
What is UN / ECE Regulation No. 65?
UN Regulation No. 65 covers type approval of special warning lamps used on specified vehicle categories. The approval distinguishes warning lamps by factors including their optical system, emitted colour, light source and whether they operate with one or two intensity levels.
The key distinction for buyers is:
- Class 1: one level of luminous intensity.
- Class 2: two levels of luminous intensity.
Class 2 therefore does not simply mean “twice as bright” or “better quality”. It means the approved lamp has two intensity levels within the approved configuration.
Why can two intensity levels be useful?
Many Class 2 products use the two approved levels as a day/night function: a higher output can be used when more warning intensity is needed, while a reduced level can help limit glare in darker conditions.
The switching method is product-specific. Depending on the lamp and installation, the second level may be controlled through wiring, a controller or another defined method. Buyers should check the product’s installation documentation rather than assume that every Class 2 lamp changes intensity automatically.
For example, reviewed VASA-Shop X9 approval evidence identifies two intensity levels, while the corresponding technical information describes day/night operation with reduced output in night mode.
How do Class 1 and Class 2 appear in approval markings?
R65 approval documents commonly show a colour/category code together with the class number. Examples from the reviewed VASA-Shop document library include:
Class 1 examples
- ANT-PRO: XA1 amber and XB1 blue.
- C12MAG: TA1 amber and TB1 blue.
- X6: XA1 amber and XB1 blue.
Class 2 examples
- FIN6: XA2 amber, XB2 blue and XR2 red.
- F6S: XA2 amber and XB2 blue.
- Instructor Air: TA2 amber and TB2 blue.
- Loki: reviewed Class 2 amber and blue approvals.
- MU Pro: reviewed Class 2 approvals for the current amber and blue configurations.
- NR6: XR2 red is verified for a current sold configuration.
- X8: XA2 amber and XB2 blue.
- X9: XA2 amber and XB2 blue.
These markings should always be checked against the actual approval certificate for the exact product type, colour and configuration being purchased. A code printed on an old brochure is not a substitute for the current homologation document.
Is Class 2 always better than Class 1?
No. Class 2 provides two approved intensity levels, which can be useful on vehicles operating in both bright and dark conditions, but the correct choice still depends on the vehicle, installation position, required colour, intended use and applicable national rules.
A Class 1 product can therefore be the correct choice for a particular application. The R65 class is one part of the specification, not a universal quality ranking.
R65 is not the same as R10
R65 and R10 address different requirements. R65 concerns the approval of the special warning lamp and its warning-light performance/configuration. R10 is a separate electromagnetic-compatibility approval.
A product may carry both R65 and R10 approvals, but “R65 Class 2” does not automatically include R10. For a compliance-sensitive purchase, check each approval separately for the relevant product configuration.
Does R65 approval mean a lamp can be used anywhere in Europe?
R65 type approval does not by itself answer every national rule governing use. National requirements can still determine which operators or vehicle types may use particular warning-light colours or configurations, and under what circumstances.
For procurement, a safer process is to:
- Confirm the exact R65 approval class and colour for the product variant.
- Confirm any separate approvals required for the product or installation, such as R10 where applicable.
- Check the national rules governing the vehicle type, operator and warning-light colour.
What should buyers check before ordering?
- Is the certificate for the exact product type or model?
- Is the approved colour the same as the colour being ordered?
- Does the approval show Class 1 or Class 2?
- If it is Class 2, how is the second intensity level controlled in the actual installation?
- Is a separate R10 approval available where required?
- Are there country-specific restrictions on the colour or vehicle use?
Frequently asked questions
What is the main difference between R65 Class 1 and Class 2?
Class 1 has one approved intensity level. Class 2 has two approved intensity levels.
Does Class 2 mean twice as bright?
No. The class designation is based on the number of approved intensity levels, not a simple “twice as bright” rule. Photometric requirements should be checked in the regulation and the relevant product approval.
Is Class 2 always required for police or emergency vehicles?
There is no universal answer. Requirements depend on the country, vehicle, use case, colour, installation and, where relevant, the tender specification.
Does R65 include EMC approval?
No. R10 is a separate electromagnetic-compatibility regulation.
Can I rely on a product brochure instead of the certificate?
For a compliance-sensitive purchase, the approval certificate for the exact configuration is the stronger evidence. Product literature can help explain features, but it should not replace the relevant approval document.
