ECE R37 Certified H11 LEDr Bulb Manufacturer for OEM and Wholesale
Features:
- Official ECE R37 Approved H11 LEDr Bulb
The EB H11 LEDr has obtained UN Regulation No. 37 type approval for its approved LEDr category. Actual road use remains subject to the approval scope, correct installation, and applicable national rules. - Universal 12V H11 Fitment by Design
Fits 12V H11 housings by design, using the standardized PGJ19-2 base and H11 envelope. Physical and electrical fitment does not by itself determine road-use legality. Confirm the product approval scope and applicable national rules before sale or installation. - Enhanced Cool White Night‑Time Visibility
Refined cool white LED output improves night‑time visibility and road contrast, providing a brighter H11 LED headlight experience while maintaining controlled glare for on‑road safety.

What is approved for this product?
UN R37 type approval applies to a defined light source type and category. It does not automatically extend to every bulb a factory sells, every brand name, or every later product change. For the EB, the approval covers the H11 LEDr type. The certificate, approval code, category designation, and durable marking on the product must correspond.
The country number beside the E-mark identifies the authority that granted the approval. It is not a country-of-origin mark, and on its own it does not prove road legality. The current UN R37 consolidated text provides the regulatory basis.
| Category | Status | Evidence boundary |
|---|---|---|
| H11 LEDr | Effective category under UN R37 | The offered product still needs a matching type approval, marking, holder, and approval document. |
| H4 and H7 | Not effective UN R37 LEDr categories | National vehicle positive-list mechanisms used in some countries are not UN R37 light source category approvals. |
Road use is narrower than physical fit. It depends on the approval conditions, installation, the receiving lamp category, and destination-market rules. UN R37 belongs to the UNECE framework and is not an EU-only regulation. In the United States, this product is for off-road use only unless separate applicable approval evidence is available.
Which specifications can buyers verify?
The EB is designed around the H11 LEDr category. Buyers should match production measurements to the approved type and review the method, sample condition, and test environment behind each reported value.
| Parameter | EB information | Verify against |

| Base and interface | ||
| Vehicle electrical system | ||
| Luminous flux | ||
| Color and chromaticity | ||
| Power and current | ||

Production measurements support sample evaluation and quality control. They complement the type-approval reports but do not replace them.
What evidence comes with an order?
The evidence pack is organized so the relationship between the product and its documents can be checked. Buyers can request a redacted type-approval communication showing the holder, approved type, regulation, H11 LEDr category, and approval code. A matching product photograph should identify the corresponding marking on the light source.
Optical, electrical, geometry, and thermal reports should identify their samples and test conditions. Production records should use the same product identity as the approval document and approved type.
Conformity of Production is an ongoing control process. Approved products must continue to meet their marking and technical requirements. UN R37 does not prescribe one universal monthly or per-batch schedule for every company, so buyers should request the actual CoP summary and records applicable to the offered product.
R10 evidence has a separate purpose. It addresses electromagnetic compatibility and does not replace the optical, geometric, thermal, or category requirements of UN R37. A product carrying only an R10 marking is not proved to be an H11 LEDr.
What should a buyer request before ordering?
Before approving a bulk order, request the certificate index, redacted approval communication, annotated marking photograph, test-report index, and CoP summary. Check that the names and identifiers agree across the pack. If a supplier provides only an E-mark photograph, ask for the document that connects the marking to the offered type.
Order samples in the intended production specification. Record bench and installation observations for the priority vehicle platforms and target markets. Sample testing confirms what you are buying, but it does not expand the approval scope.
How does fit by design affect vehicle checks?
The EB is designed around the standardized H11 interface, including the PGJ19-2 base and category geometry. A generic retrofit may depend on a long vehicle list because its body or emitter location does not follow the category envelope.
Fit by design is not an unconditional compatibility promise and does not turn physical installation into a road-use claim. Dust-cap clearance, connector access, bulb-outage detection, and other vehicle-specific behavior should still be checked during sample testing.
How do OEM and wholesale orders work?
Private label is not a certificate-loan arrangement. When only the trademark changes and the same manufacturer produces a fully identical product, the applicable approval procedure requires documented handling before the branded product is presented as approved.
Packaging artwork and brand presentation are the normal customization areas. The approval marking, category, rated voltage, LEDr identification, applicant identity, and restricted-use information cannot be changed freely. Any change affecting optical output, base or emitter geometry, electronics, ratings, thermal behavior, or approved type identity requires an approval assessment.

Frequently asked questions
Which halogen category does the EB replace?
The EB is an H11 LEDr using the PGJ19-2 H11 interface. It replaces H11 filament bulbs in lamps approved with H11 light sources under the same category designation. It is not an H7, H4, or another category.
Where is the approval number shown on the bulb?
The bulb body carries the approval marking and category identification. Match the complete marking, approval code, H11 LEDr designation, product type, and approval holder to the approval communication. An E country identifier alone is not sufficient.
What voltage systems does the EB support?
The offered EB version is built for 12 V vehicle electrical systems. Confirm the approved rating, operating range, and test conditions in the current product specification and approval documentation before ordering.
Do I need a CANBUS decoder?
Compatibility with bulb-outage detection varies by vehicle. Test samples on priority models and confirm the exact EB electronics configuration with LEDOAUTO before approving the production specification.
Which documents come with an order?
The available evidence pack includes the redacted type-approval communication, applicable optical and electrical test documentation, the CoP summary, and R10 electromagnetic compatibility evidence. Request the current document index before ordering.
What can be customized without affecting the approval?
Brand and packaging visual content may be handled through the applicable private-label procedure for an identical product. Changes to optics, electronics, geometry, ratings, thermal behavior, or approved type identity require an approval assessment.
What is the MOQ?
MOQ depends on whether you use the standard product and packaging or require custom branding and packaging. Send the destination market, forecast, and packaging brief to receive the current MOQ and any approval-related sample requirements in writing.
What warranty applies?
Warranty and RMA terms depend on the confirmed product version and order agreement. Request the current written terms, including the coverage period, evidence required for a claim, handling of failed units, and exclusions for incorrect installation or use outside the agreed market conditions.
How do I order samples?
Send your company name, target markets, voltage requirement, priority vehicle platforms, and packaging plan. LEDOAUTO will confirm the current sample cost, lead time, available documentation, and whether the sample charge can be credited against a later bulk order.
Which markets can the EB be sold in?
UN R37 approval is relevant in markets applying UNECE regulations under the 1958 Agreement. Actual road use remains subject to the approval scope, correct installation, and destination-market rules. In the United States, market this product for off-road use only unless separate applicable approval evidence is available.
