Automotive Ambient Lighting Specification Example for Racing Teams: Racing Spec

This is a worked specification for automotive ambient lighting in a racing spec 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 racing spec version exists because the duty cycle on racing teams is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually a fitment that looked right on paper and failed on the bench.

How the example is built up

  1. Start from the duty cycle, not from the catalogue photograph.
  2. Fix the base material in writing — Reinforced Nylon, in this example.
  3. List the dimensions that are actually controlled and the tolerance on each.
  4. Name the finish and what it has to survive.
  5. State the inspection level and who pays when a lot fails.

Processes involved

  • precision stamping
  • injection moulding
  • rubber vulcanisation
  • ultrasonic cleaning
  • robot welding
  • die casting

Where this example applies

Programmes that run racing spec most often specify this build for racing teams. Related applications include off-road bikes, agricultural trailers, construction equipment, courier fleets, delivery vans.

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

Can the specification be held on file?

Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the SAE J431-compliant build instead of a fresh interpretation.

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.

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 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.

Send the specification you are working to and we will confirm what we can match, what we would change and why.
