Who we build for

Trailer classes we supply

Each class carries its own FMVSS 108 lighting set — these are the ones we build parts for every day.

In-line automationMoulded parts come off the press and move straight into assembly on the floor above.

We own the tooling, the presses and the line

Mould design, five-axis optical machining, injection moulding, assembly and photometric verification all happen under one roof.

  • 16Injection moulding presses — 13 × 200 t, 3 × 400 t. All brand new, no second-hand machines.
  • 5Machine-side automation lines, built around the part rather than bolted on afterwards.
  • 3Fully automatic assembly and inspection lines.
  • 100%In-line inspection coverage, every unit.

Quality & compliance

Regulation is a design input, not a final inspection

We build to the clause from the first CAD revision, verify photometry in our own lab and confirm it with U.S.-based testing laboratories.

  • FMVSS 108 & 125 covered

    Photometric design and verification run in parallel across the part categories we produce.

  • Third-party verification

    Photometric results are confirmed by U.S.-based testing laboratories, not only in our own darkroom.

  • ISO 9001:2015 certified

    Certificate PCC85725Q01560R0S, valid to 1 Sep 2028, annual surveillance.
