Manufacturers, component suppliers and importers preparing a new front lighting devices type, product range, variant or engineering change for Vietnam.
When the service is needed
- A new product or range is planned for the Vietnamese market.
- Evidence under UN Regulation No. 149 and relevant installation requirements, when applicable exists, but its relevance and scope require review.
- A product family and representative sample must be defined.
- A change may affect testing, certification documentation, markings or COP.
What the customer should prepare
- Device functions and intended vehicle applications.
- Optical, mechanical and electrical drawings, light-source data and markings.
- Test reports, UNECE approvals and extension documents.
- Variant matrix, production site and proposed sample.
What LotusTSE does
- Define the type or family boundary from the actual lighting function, light source, optical system, housing, variants, markings and vehicle installation context.

- Check traceability across product, marking, test report, approval document and approval scope.
- Identify gaps, representative samples, test work, technical-file actions and relevant COP controls.
What the customer receives
- Product-scope and family matrix.
- Requirements-to-evidence matrix with verification points and gaps.
- Representative-sample and test-plan proposal.
- Reviewed technical-document list and prioritized next actions.
Risks identified and reduced
The review helps identify treating unlike lighting functions as one scope, missing an approval or marking limitation, selecting an unsuitable sample, or separating the device assessment from relevant installation conditions, reducing avoidable repeat work and late documentation changes. UNECE evidence is reviewed case by case and is not presented as automatically accepted in Vietnam.
Project coordination
How the project is managed
The parties agree the scope, deliverables, responsibilities and indicative milestones before work starts. A LotusTSE technical focal point tracks work items, information awaiting customer input, identified risks and next actions. Milestones that depend on an authority, laboratory or other external organization are updated against actual status.
