OEM and aftermarket describe supply contexts; neither label alone proves that a part fits an installation or meets a particular requirement. Compare the exact specification, evidence and order conditions.
New vehicle integration and replacement sourcing
A new vehicle project starts from the vehicle builder’s interfaces and validation requirements. A replacement enquiry starts from the installed system and its condition. Both routes need a clear product identity, installation review and agreed supply scope.
LEILI model references and identification
LEILI SKU references identify its own products or layout forms. They are not OE-number cross-references. For a replacement, provide photographs, the label or LEILI reference if known, dimensions and electrical details. For a new system, provide the windshield and mounting drawing with the required arrangement.
Compare the offer rather than the label
| Question | Check |
|---|---|
| Fitment | Dimensions, shaft, mounting, connector, parking and layout requirements. |
| Configuration | Exactly which motor, linkage, arms, blades and washer items are included. |
| Evidence | Current documents and selected-model test or sample records. |
| Commercial scope | Quantity, tooling or development, packaging and delivery terms. |
| Support | Warranty coverage, excluded consumables and claim review process. |
Avoid assumptions about equivalence
Matching power, length or appearance is not enough to establish interchangeability. A lower price is not a saving if the configuration differs. Management-system certification does not independently establish a selected product’s performance. Review missing information before making the sourcing decision.
Confirm the order
Record the accepted drawing revision, electrical variant, component list and agreed sample checks. LEILI wiper blades have no warranty; other products and components have a one-year warranty from delivery under the published terms. For supplier due diligence, use the manufacturer evaluation checklist.
Send the information needed for a technical review
Send installation photographs, the LEILI model if known, measured dimensions or a drawing, electrical supply and quantity. LEILI model numbers identify our own products or layout references; they are not OE-number cross-references. Contact LEILI for a configuration review.
