Car Headlight Tint Film Specification Example for City Buses: All-Weather Version
Car Headlight Tint Film Specification Example for City Buses: All-Weather Version
This is a worked specification for car headlight tint film 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 city buses 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.

- die casting
- injection moulding
- powder coating
Where this example applies
Programmes that run all-weather version most often specify this build for city buses. Related applications include dealership service, three-wheelers, fleet maintenance, city buses, rental motorcycles.
Checks before packing
- Dimensional report against the approved drawing.
- AQL 1.5 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
How long does sampling take?
Samples leave the factory in 10 working days, and each revision round adds about 5 days once you have seen the first piece.
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.
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.
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 200 pieces per line.
Share a sample or a drawing and we will quote against a written specification, not against a photograph.
