Car Rear Lamps Specification Example for Passenger Cars: Heavy Duty
Car Rear Lamps Specification Example for Passenger Cars: Heavy Duty
This is a worked specification for car rear lamps in a heavy duty 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 heavy duty version exists because the duty cycle on passenger cars is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually packing that arrived crushed at the port.

Example specification
| Item | Car Rear Lamps |
|---|---|
| Application | Passenger Cars |

| Compliance | ISO/TS 16949 |
How the example is built up
- Start from the duty cycle, not from the catalogue photograph.
- Fix the base material in writing — Neoprene, 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
- ultrasonic cleaning
- die casting
- anodising
- sintering
- electroplating
- heat treatment
Where this example applies
Programmes that run heavy duty most often specify this build for passenger cars. Related applications include assembly programmes, off-road bikes, city buses, trailer axles, light trucks.
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.
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.
What is the minimum order quantity?
The standard MOQ is 2000 pieces per specification. Mixed sizes inside one shipment are accepted once the total reaches that figure.
Can the specification be held on file?
Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the ISO/TS 16949-compliant build instead of a fresh interpretation.
Share a sample or a drawing and we will quote against a written specification, not against a photograph.
