National approval and harmonized LEDr approval are not the same thing
No adopted harmonized Group 5 H7 or H4 LED replacement category sheet was identified in the official R.E.5 material reviewed as of 21 July 2026. That means a supplier should not present H7 or H4 as established harmonized UN R37 LEDr categories today.
At the same time, specific H7 and H4 LED retrofit products can be approved through national or application-specific routes in selected markets. Those approvals can be valid within their actual scope. The mistake is not using a national route; the mistake is describing that route as though it were a universal UNECE light-source category approval.
What the absence of an H7 or H4 Group 5 sheet actually means
R.E.5 Group 5 contains technical category specifications for harmonized LED replacement light sources. When a category is adopted, an exact manufactured type can seek approval against that standardized route under the applicable light-source regulation.
For H7 and H4, the reviewed R.E.5 materials do not yet show adopted harmonized Group 5 category sheets. This is a regulatory boundary, not a worldwide ban. It says the harmonized light-source route is not yet established for those categories; it does not erase national approvals that exist under separate legal mechanisms.
That distinction is essential for importers and brands because the evidence file, market scope and fitment control can look very different depending on which route the product uses.
The two routes answer different questions
| Route | What is primarily approved | How scope is controlled |
|---|---|---|
| Harmonized LED replacement category | A defined light-source type assessed against an adopted category specification | Exact approved type, configuration, marking and applicable market requirements |
| National/application-specific retrofit route | A named product under a national approval basis | Country, vehicle/headlamp applications, light function and required accessories |
A harmonized route does not approve every bulb sharing the same base. Product type approval is still required. A national route is not automatically weaker or invalid; it is narrower and usually requires more application-specific control.
This is why the first buyer question should be “Which approval route does this exact product rely on?” rather than simply “Does it have an E-mark?”
Positive lists are central to many national retrofit approvals
Public approval-holder compatibility lists show how a national H7 or H4 route can be tied to the exact vehicle, production period, headlamp approval number, light function and required accessories. A product may be approved in one headlamp application and not covered in another vehicle that uses the same nominal bulb category.
This is why physical fit is not the same as approval coverage. A bulb may plug in and illuminate while the vehicle, headlamp or accessory combination still falls outside the documented approval.
Adapters, electronics modules or replacement rear caps can also be part of the approved combination. The positive list is therefore more than a retail fitment chart; it is part of the scope-control mechanism for the named product.
One national approval does not automatically become a Europe-wide claim
National approvals operate within their legal and recognition framework. A product approved in one market should not automatically be described as “street legal in Europe” unless the actual recognition basis supports that wording.
The same caution applies in the other direction. The absence of a harmonized H7 or H4 category does not mean that every nationally approved product is illegal outside its home country. Recognition must be checked market by market against the applicable law and approval conditions.
For B2B catalogues, the safest structure is to name the route, exact product and verified market scope instead of using a single badge to cover every country.
Most misleading claims come from mixing the two routes
| Claim | Why it is risky |
|---|---|
| ECE-approved H7 LEDr | Can imply an adopted harmonized H7 LEDr category that does not currently exist in the reviewed R.E.5 material |
| H4 street legal in Europe | Turns market-specific approval into a broad regional claim |
| Fits H7, therefore approved | Socket compatibility does not prove application coverage |
| R10 approved, therefore road legal | R10 is EMC evidence, not the lighting approval route |
A precise claim may look less dramatic, but it is stronger commercially because a distributor can trace it back to the actual approval and application scope.
What to request before accepting an H7 or H4 road-use claim
- Exact product reference and regulatory type.
- The named approval route and approval holder.
- The complete approval document rather than a cropped logo or mark.
- The current compatibility or positive list where the route uses one.
- Vehicle and headlamp identification method.
- Required accessories and installation conditions.
- The destination-market basis for the sales claim.
- Change-control rules when the product or accessory set is revised.
For the engineering reasons H7 and H4 are difficult to standardize, see the dedicated H7 and H4 technical explainers rather than treating the approval route itself as an engineering specification.
H7 and H4 approval questions
Are H7 and H4 harmonized LEDr categories today?
No adopted Group 5 H7 or H4 LED replacement category sheet was identified in the official R.E.5 material reviewed as of 21 July 2026.
Can a specific H7 or H4 LED retrofit still be road legal?
Yes, where a valid national or application-specific approval covers the exact product, market and installation.
Is a positive list the same as a harmonized category sheet?
No. A positive list controls applications for a specific approval route; a category sheet defines a standardized light-source category.
Does a national approval automatically apply across Europe?
No universal assumption should be made. Recognition and market conditions must be checked separately.
Official and approval-holder sources
- UNECE, Consolidated Resolution R.E.5 register
- German Federal Motor Transport Authority, ABG definition
- OSRAM, published compatibility-list example
National approval scope must be checked against the named product, current application list, required accessories and destination market.
