A Premier Industrial Scale Leader in Smart Automotive Lighting and Integrated OEM/ODM Services Since 2012.
Established in 2012, Ningbo DERT Lighting Co., Ltd. is a highly distinguished and professional manufacturer specializing in state-of-the-art automotive lighting systems, high-intensity LED headlights, and advanced vehicle lighting solutions tailored specifically for the global automotive aftermarket and prestigious OEM clients. Headquartered strategically in the industrial port city of Ningbo, Zhejiang Province, China, our company coordinates all engineering, design, and supply logistics from our massive modern production facility covering approximately 18,000 square meters.
DERT Lighting currently manages a robust workforce of more than 320 skilled professionals spanning dedicated R&D engineering divisions, quality assurance departments, precision manufacturing teams, and our experienced international sales network. By integrating optical analysis, advanced thermal dissipation models, and custom SMT electronics assembly, we provide solutions that satisfy stringent international vehicle safety criteria.
Our comprehensive focus remains on the development and automated manufacturing of key illumination technologies, including high-power LED headlight systems, signal devices, specialized commercial vehicle lighting assemblies, off-road lighting bars, and custom PMMA/PC optics. Backed by extensive CNC prototyping, aluminum die-casting, and optical laboratories, DERT Lighting serves primary importers, distributors, automotive brands, and fleet operators globally.
Why Tier-1 Automotive Buyers Choose Ningbo as Their Primary Procurement Base.
Ningbo is situated at the epicenter of China's manufacturing ecosystem, meaning raw materials like aluminum castings, custom automotive-grade PCB assemblies (PCBA), PMMA lenses, and LED chips are sourced within a 100km radius. This localized infrastructure dramatically reduces turnaround times and lowers production costs.
Our plant integrates fully automated surface mount technology (SMT) lines to populate electronic circuits with high precision. By eliminating manual soldering, we prevent electrical failures and enhance the durability of LED driver boards working under extreme vehicle vibration patterns.
With fully equipped CNC machining workshops, DERT Lighting offers unmatched speed in building functional prototypes. Whether it is an OEM custom PMMA projector lens or a structural aluminum die-cast housing, we move from designs to physical samples in a fraction of the standard time.
How Modern Safety Requirements and Next-Gen Optical Technologies Shape the Future of Vehicle Illumination.
The automotive landscape is transitioning rapidly from basic static high beams to dynamically adjusting Adaptive Driving Beams (ADB). Through matrix LED technology linked to vehicle-mounted cameras, light beams automatically dim around oncoming cars to prevent glare while maintaining full illumination elsewhere. As a forward-thinking China supplier, DERT is continuously investing in matrix controller PCB designs to keep our global clients competitive.
Modern LED headlights operate at extremely high power levels (some exceeding 180W), generating substantial heat at the junction point. Effective thermal management through advanced copper heat pipes, liquid cooling channels, and optimized aluminum alloy die-cast heat sinks is essential to prevent degradation in luminous flux and ensure a lifespan of over 50,000 hours.
New vehicle electronics require smart components that do not trigger dash error codes or cause radio interference. Our engineers design integrated decoding circuits with built-in electromagnetic compatibility (EMC/EMI) filters to ensure flicker-free operation and plug-and-play installation on complex vehicle platforms.

Fully certified customized lighting architectures for diverse commercial, industrial, and passenger applications.
Long-haul trucks require rugged, heavy-duty lighting solutions that withstand thousands of kilometers of constant road vibration. Our solutions, including heavy-duty rear license plate lamps (like model LG9704810003 for HOWO trucks) and 24V LED side marker lamps, are optimized for peak performance and extreme durability in continuous fleet operations.
Excavator and construction environments generate massive amounts of dust, moisture, and high-impact shocks. DERT manufactures high-lumen 3-inch, 4-inch, 5-inch, and 7-inch LED work lights engineered with IP68/IP69K sealing and heavy impact-resistant polycarbonate lenses to ensure workplace safety in harsh environments.
Modern electric vehicles (such as the BYD Qin) necessitate energy-efficient, sleek, and adaptive front headlights that minimize battery drainage. Our aerodynamic, lightweight LED assemblies support smart DRLs (Daytime Running Lights) and adaptive leveling controllers to maximize vehicle driving range.
Understanding the critical quality standards and compliance frameworks expected by international Tier-1 buyers.
Global automotive component procurement involves strict regulatory hurdles. Importing to the United States requires compliance with the Federal Motor Vehicle Safety Standards (FMVSS) under DOT certification. Entering European markets requires compliance with ECE regulations (indicated by E-mark compliance certificates). Without these certifications, vehicle importers face significant customs issues and legal liabilities.
DERT Lighting implements an IATF 16949-aligned quality management workflow that ensures all manufactured lots match approved prototype parameters. In addition, our factory runs continuous salt spray testing, goniophotometric evaluations, and thermal chamber tests to verify that every single LED headlight bulb maintains beam uniformity and zero failure rates under sub-zero or desert heat conditions.
Furthermore, modern automotive purchasing departments seek vertical integration. Instead of buying drivers, optical elements, and die-cast bodies from different factories, buyers prefer a single partner like DERT. We provide integrated solutions: from prototype PCB assembly (PCBA) and high-quality aluminum die-casting to rapid prototype CNC machining, creating a highly efficient supply chain.
