Case Study: Turn Signal Lamp Supply for a motorcycle assembler in Central Asia

Turn Signal Lamp for A motorcycle assembler in Central Asia

A motorcycle assembler came to us with a turn signal lamp programme for Central Asia. The brief was ordinary and unforgiving at the same time: a fixed launch window, a landed cost that had to survive freight and duty, and a part that had to match an existing sample. This case records what was specified, what went wrong in sampling and how the bulk order landed.

The starting point

  • Documentation that arrived after the container shipped
  • Warranty claims traced back to a single lot
  • Reorders that did not match the approved sample

ClientA motorcycle assembler
MarketCentral Asia
Volume20,000 pieces across 3 specifications
Base materialCast Iron
Sampling rounds4
Delivery window5 weeks from PO to ex-factory
ComplianceIATF 16949

How it was resolved

  1. The specification was rebuilt around Cast Iron and the tolerance locked before bulk.
  2. A pre-production sample was approved and kept as the golden reference.
  3. Production ran with in-line inspection and a mid-run photo report.
  4. Cartons were packed to the client's own barcode and ratio specification.
  5. Documentation shipped with the goods instead of after them.

Result

  • 20,000 pieces delivered inside the 5-week window.
  • Unit cost held within 1.5% of the original quotation.
  • Inspection-related rejection stayed under 0.5%.
  • The specification is on file, so reorders reproduce the approved sample.

What we would repeat

Lock the material standard before sampling. Once the base changes, every downstream approval has to be redone and the calendar slips.
