Trailer Tail Lights Specification Example for Export Programmes: Adjustable Type
Trailer Tail Lights Specification Example for Export Programmes: Adjustable Type
This is a worked specification for trailer tail lights in a adjustable type 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 adjustable type version exists because the duty cycle on export programmes is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually documentation that arrived after the container shipped.
Example specification

How the example is built up
- Start from the duty cycle, not from the catalogue photograph.
- Fix the base material in writing — High Density Foam, 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
- precision stamping
- gravity casting
- laser cutting
- powder coating
- cold forging
- injection moulding
Where this example applies
Programmes that run adjustable type most often specify this build for export programmes. Related applications include aftermarket retail, export programmes, three-wheelers, agricultural trailers, rental motorcycles.
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
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 1000 pieces per line.
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.
What testing is included?
Standard lots ship with dimensional and hardness reports. SAE J431 documentation is issued with the shipment when your market requires it.
How long does sampling take?
Samples leave the factory in 14 working days, and each revision round adds about 5 days once you have seen the first piece.
