TA YIH Business Summary

Ta Yih Industrial Co., Ltd. (1521.TW) operates as a premier Original Equipment Manufacturer (OEM) and Original Design Manufacturer (ODM) specializing in automotive lighting systems, including LED headlights, rear combination lamps, and fog lights. The company generates revenue through the high-volume sale of integrated lighting solutions to major global automakers, supported by a vertically integrated business model that spans optical design, precision mold manufacturing, and automated assembly. Its primary business segments are categorized by geographic market and vehicle type, with a dominant share in the Taiwanese domestic OEM market (supplying Kuozui/Toyota and Yulon/Nissan) and a robust export division serving North American and Japanese Tier-1 clients. Ta Yih competes directly with Depo Auto Parts, TYC Brother Industrial, and Ichikoh Industries; it maintains a superior market position in the OEM segment through its specialized focus on high-specification technical requirements and long-term supply contracts. Founded in 1964 by Chairman Wu Chun-Chi, Ta Yih has evolved from a local manufacturer into a regional leader under the continued stewardship of the Wu family. The current leadership team is led by Chairman Wu Chun-Chi and General Manager Wu Chao-Li, who bring decades of experience in automotive optics and manufacturing strategy to the executive suite. A defining feature of the company’s corporate structure is its strategic alliance with Japan’s Koito Manufacturing Co., Ltd., which serves as both a major shareholder (holding approximately 32% of equity) and a key technical partner. This partnership provides Ta Yih with a significant technological pedigree, particularly in Adaptive Driving Beam (ADB) and advanced LED technologies, while the board of directors remains a blend of founding family members and representatives from Koito, ensuring a stable governance structure and access to global automotive supply chains.
