Integrated Rear Lights Specification Example for Scooter Fleets: Long Life Version
Integrated Rear Lights Specification Example for Scooter Fleets: Long Life Version
This is a worked specification for integrated rear lights in a long life version programme. It is the document we would send a buyer who asks what exactly they are getting: the material, the dimensions that are actually controlled, the finish, and the checks that happen before anything is packed.
The long life version version exists because the duty cycle on scooter fleets is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually inconsistent hardness between lots.

Example specification
| Item | Integrated Rear Lights |
|---|---|
| Application | Scooter Fleets |
| Version | Long Life Version |
| Base material | Titanium Alloy |
| Controlled dimensions | 6 key dimensions, recorded per lot |
| Tolerance band | ±0.2 mm |
| Finish | anodised |
| MOQ | 200 pieces per specification |
| Sampling | 7 working days, 3 days per revision |
| Compliance | ECE R90 |
How the example is built up
- Start from the duty cycle, not from the catalogue photograph.
- Fix the base material in writing — Titanium Alloy, in this example.
- List the dimensions that are actually controlled and the tolerance on each.
- Name the finish and what it has to survive.
- State the inspection level and who pays when a lot fails.

Processes involved
- gravity casting
- assembly line testing
- die casting
- CNC machining
- robot welding
- powder coating
Where this example applies
Programmes that run long life version most often specify this build for scooter fleets. Related applications include three-wheelers, trailer axles, dealership service, utility trailers, camper conversions.
Checks before packing
- Dimensional report against the approved drawing.
- AQL 2.5 sampling on the finished lot.
- Finish inspection under agreed lighting.
- Carton drop test on the first lot of a new packing specification.
Questions buyers ask
Can the specification be held on file?
Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the ECE R90-compliant build instead of a fresh interpretation.
Can you match an existing sample?
Send a sample and we will reverse-engineer the specification, then produce a counter sample for approval before any bulk starts.
How is packing specified?
Individual packing, inner box quantity and carton marking are confirmed at quotation stage so the cartons arrive ready for your warehouse.
How long does sampling take?
Samples leave the factory in 7 working days, and each revision round adds about 3 days once you have seen the first piece.
Share a sample or a drawing and we will quote against a written specification, not against a photograph.
