Methodology

How the estimates were built: data sources, modelling approach and validation steps.

Research approach

A market size is a claim about the world, and a claim is only as good as the route to it. Every study is built upward from units and prices — what is actually produced, sold or performed, at what it actually changes hands for — rather than from a headline figure divided downwards. Disclosed company revenue is then used to check that build, not to produce it.

Market size estimation, this report

CDI sizes the automotive lamp housing market bottom-up, building from global light-vehicle and commercial-vehicle production volumes, average housing units fitted per vehicle across front, rear, side and interior positions, and per-unit pricing by material and technology, aggregated upward to a production-linked revenue base by region. That build is checked against OEM lighting-system procurement budgets and aftermarket collision-repair parts spending reported by distributors and repair networks, isolating the housing-specific share of the broader lighting-component category. Where the check diverges from the bottom-up figure, the correction runs through the bottom-up assumption itself — typically the units-fitted or material-mix estimate for that region — rather than averaging the two together.

The four stages

The same sequence runs behind every published study, whatever the industry. The order matters as much as the steps: the segment axes are fixed before any number is collected, so the model is never reshaped to fit whatever data happens to turn up.

What the build rests on, and what checks it

The two are not interchangeable. The left column produces the number; the right column tests it. When the check disagrees with the build, the answer is to find which bottom-up assumption is wrong — a unit count, a price, a take-up rate — not to split the difference between them.

The bottom-up build rests on
  • Volume actually transacted — units produced, installed, dispensed or procedures performed, counted at the level each is genuinely recorded
  • Realised pricing by tier and channel, rather than one blended average applied across the whole market
  • Take-up and frequency: how much of the addressable base buys, and how often it repeats
The build is checked against
  • Disclosed revenue of the companies serving the market, where filings separate it far enough to be usable
  • Buyer-side spending totals — capital budgets, procurement lines, or the output of the end market the product is bought against
  • Trade and customs flows, where the product crosses borders in a separately recorded form

Data sources

Published data establishes what happened. Only the people transacting in a market can say why, and what is about to change — so the two are collected separately and weighted differently.

Primary — who is interviewed
  • Commercial and product leadership at the companies that supply the market
  • Procurement and specification leads at the organisations that buy it
  • Distributors, integrators and channel partners, where the market is served indirectly
  • Regulatory and standards specialists, where approval governs what can be sold at all
Secondary — what is read
  • Company filings, annual reports and investor disclosure
  • Government statistics, customs records and regulatory registers
  • Trade association output and standards-body publications
  • Technical and peer-reviewed literature, where the market rests on a clinical or engineering claim
Primary research design, this report

Primary research targets procurement and engineering contacts at vehicle manufacturers responsible for lighting-system sourcing, product managers at Tier 1 lighting suppliers, purchasing leads at parts distributors and collision-repair chains, and regulatory contacts tracking regional lighting-safety standards that influence housing design. Sampling emphasises Asia Pacific, where vehicle production and lighting-technology transitions are concentrated, alongside Europe and North America, where OEM design-in decisions and aftermarket replacement patterns are tracked separately. Conversations focus on sourcing criteria, material and technology transition timing, and regional pricing differences between OEM and aftermarket channels. Findings are checked against public company disclosures, trade-association production data and customs trade records before being folded into the sizing model.

Secondary sources, this report

CDI's desk research for the lamp housing market draws on vehicle lighting homologation filings under ECE Regulation 48 and FMVSS 108, which document the housing and lens specifications submitted for type approval by region. Customs trade data under HS code 8512.20 tracks cross-border shipment volumes of lighting equipment, including finished housings and sub-assemblies. OICA production statistics anchor vehicle-parc assumptions, while public filings from Koito, Valeo, Marelli, Hella and Stanley Electric provide segment revenue and capacity disclosures. Polycarbonate resin pricing indices from material suppliers and aftermarket collision-repair parts catalogs round out the cost and replacement-demand picture.

Desk research runs across proprietary research databases including Factiva, OneSource and Hoovers alongside the public sources above. Modelling and statistical validation are run in SAS and SPSS.

Forecasting

The forecast is not a growth rate applied to a base year. It is built from the drivers that are expected to change, each one stated so a reader can disagree with it.

Forecast approach, this report

The forecast is built from projected light-vehicle and commercial-vehicle production schedules, the pace at which LED housings displace halogen across OEM trims, and the lighting-safety mandates in Europe and Asia Pacific that are pushing adaptive and matrix-LED designs into mid-tier vehicles rather than premium models alone. Aftermarket demand is modelled off the existing vehicle parc's aging profile and collision-repair frequency, distinct from OEM design-in cycles. The 2020-2021 production shortfall tied to semiconductor shortages is treated as a one-off disruption rather than a trend, with volumes normalized against pre-shortage production growth. The forecast holds if vehicle production recovers along its historical trajectory and LED conversion continues at its observed regional pace without a material resin-price shock.

Triangulation and validation

No figure enters a report on the strength of one source. Where the two sizing routes disagree the difference is not averaged away — the assumption causing it is isolated, tested against a third independent measure, and either corrected or carried forward as a stated limitation. Historical years are back-tested against the growth actually recorded before any forecast is allowed to run forward from them.

Validation, this report

Sizing outputs are back-tested against recorded 2020-2024 lamp housing revenue growth by region, checking that the model's historical estimates track publicly reported production and shipment trends rather than being fit only to the forecast period. Segment-level shifts, particularly the pace of LED share gains against halogen and the OEM-versus-aftermarket split by region, are reviewed with the primary-research contacts who supplied the underlying sourcing and technology-transition input. Sensitivities are run on vehicle production growth, resin and polycarbonate input costs, and the timing of adaptive-lighting regulatory mandates, with the resulting revenue range narrowed once two of the three variables move within their expected bounds.

Confidence and limitations

Where an estimate is firm and where it is not is stated rather than left to be inferred from the precision of the number.

Confidence framing, this report

Confidence is highest in the OEM passenger-car segment across Asia Pacific, Europe and North America, where production volumes, homologation filings and supplier disclosures are all independently verifiable. It is lower in the aftermarket channel across Latin America and Middle East and Africa, where collision-repair activity is fragmented across informal and unorganized workshops with limited reporting. Interior and side-lighting housings, a smaller and less standardized category, carry wider estimate ranges than front and rear housings. A sustained resin-price shock or a faster-than-modelled halogen-to-LED transition are the two developments most likely to force a revision to these figures.
