Automotive Tail Light Specification Example for Utility Trailers: All-Weather Version
Automotive Tail Light Specification Example for Utility Trailers: All-Weather Version
This is a worked specification for automotive tail light in a all-weather 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 all-weather version version exists because the duty cycle on utility trailers is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually premature wear on the first batch.

- cold forging
- injection moulding
- sintering
- ultrasonic cleaning
Where this example applies
Programmes that run all-weather version most often specify this build for utility trailers. Related applications include racing teams, utility trailers, boat trailers, camper conversions, delivery vans.
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
How long does sampling take?
Samples leave the factory in 10 working days, and each revision round adds about 3 days once you have seen the first piece.
What is the minimum order quantity?
The standard MOQ is 500 pieces per specification. Mixed sizes inside one shipment are accepted once the total reaches that figure.
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 is packing specified?
Individual packing, inner box quantity and carton marking are confirmed at quotation stage so the cartons arrive ready for your warehouse.
