Trailer Tail Lights Specification Example for Scooter Fleets: OEM Replacement
Trailer Tail Lights Specification Example for Scooter Fleets: OEM Replacement
This is a worked specification for trailer tail lights in a oem replacement 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 oem replacement 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 lead time that slipped twice before bulk started.
Example specification
| Item | Trailer Tail Lights |
|---|---|
| Application | Scooter Fleets |
| Version | OEM Replacement |

| 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 — Forged Aluminium, 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
- shot blasting
- anodising
- powder coating
- CNC machining
- injection moulding
- gravity casting
Where this example applies
Programmes that run oem replacement most often specify this build for scooter fleets. Related applications include light trucks, city buses, courier fleets, municipal fleets, fleet maintenance.
Checks before packing
- Dimensional report against the approved drawing.
- AQL 4.0 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 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.
What testing is included?
Standard lots ship with dimensional and hardness reports. ECE R90 documentation is issued with the shipment when your market requires it.
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.
What happens if a lot fails inspection?
The lot is re-inspected against the golden sample, and replacement pieces ship on the next available booking at our cost.
Send the specification you are working to and we will confirm what we can match, what we would change and why.
