The substitution of halogen and xenon lamps by LED headlights is largely complete, bringing the automotive lighting industry to a crossroads of technological divergence. On the headlamp front, ADB (Adaptive Driving Beam) is accelerating its penetration into mid-tier vehicle models, while two new solutions—DLP (Digital Light Processing) projection headlamps and Micro LED—are extending lighting functions to road surface projection and lane guidance. On the taillight front, full-width LED taillights are rapidly gaining popularity in NEVs (New Energy Vehicles), and OLED and Mini LED technologies are transforming taillights from mere signal indicators into programmable dynamic interfaces. This divergence in technological routes is driving the automotive lighting supply chain into a new round of adjustment.
Gasgoo Research Institute has conducted a study and analysis of the automotive lighting supply chain from three dimensions: overview of automotive lighting, corporate competitive landscape and typical enterprise profiles, and profiles of representative suppliers for key components.
Excerpts from the report are as follows:
Automotive lights are categorized into three main types based on function: lighting lamps, signal lamps, and decorative lamps. They consist of six core components: light sources, reflectors, lenses, lamp covers, lamp bases, and seals. Headlamps represent the highest value-added component within the lighting system, with raw material costs accounting for over 60% of the total cost. As smart lighting and projection interaction features are progressively introduced, the per-vehicle lighting system value continues to rise; nevertheless, cost control of components remains the foundation of competitiveness for lighting enterprises.
Core Insights of This Report:
Diversification of headlamp light source solutions for passenger vehicles: Matrix LED has the largest installation scale, laser headlamps are positioned for high-end high-beam enhancement, and Micro LED opens up new scenarios with pixel-level light control precision. These three light sources cater to different price points and functional positioning.
Raw materials account for the highest proportion of headlamp costs, with electronic components and plastic materials being the two largest expenditures among them. Enterprises are primarily pursuing cost reduction through two pathways: light source solution substitution and injection molding process integration.
Technological barriers are concentrated in three areas: thermal management, optical design, and drive control. Thermal management determines the sustained performance of the light source, optical design dictates light distribution precision and beam pattern quality, and drive control determines the effectiveness of smart feature implementation.
According to the Gasgoo Configuration Database, the global headlamp market grew from 183.8 billion RMB in 2022 to 293.5 billion RMB in 2025. Over the same period, the Chinese market size expanded from 58.4 billion RMB to 140 billion RMB, with a growth rate exceeding the global average, and the LED headlamp penetration rate reaching 86%.
The upstream segment of the automotive lighting industry chain encompasses sub-sectors such as LED chips and packaging, optical components, structural components, and electronic components. The midstream consists of various assembly manufacturers for headlamps, taillights, signal lights, and ambient lighting. Companies like HASCO Vision, Xingyu Automotive Lighting, Valeo, HELLA, and Koito form the first tier, while the downstream serves domestic and international passenger vehicle OEMs. As light source technologies iterate towards Micro LED and laser directions, and ADB, DLP projection, and interactive taillights are successively introduced, the technological upgrading of the industry chain revolves around optical design, electronic control, and software algorithms. Domestic suppliers have already demonstrated strong supporting competitiveness in certain segments.
