Explore our core engineering assemblies and custom lighting systems developed for precision road safety, off-road applications, and automotive cabin environments.
Established in 2012, Ningbo DERT Lighting Co., Ltd. has evolved into an international powerhouse specializing in the engineering, design, and manufacturing of premium automotive lighting systems and accessories. Strategically stationed in the industrial hub of Ningbo, Zhejiang Province, China, DERT operates an expansive state-of-the-art facility covering over 18,000 square meters.
We deploy a robust workforce of more than 320 highly trained professionals across dedicated divisions: Optoelectronic Engineering, High-Precision Injection Molding, Advanced SMT & PCB Assembly (PCBA), Cleanroom Headlamp Assembly, Regulatory Compliance, and Global Distribution Logistics. This streamlined vertical integration empowers us to provide robust OEM and ODM solutions for global aftermarket distributors and Tier-1 automotive assembly supply chains.
Our operation is built upon rigorous scientific product development. By combining high-precision optoelectronic components with custom-designed heat sinks and proprietary circuit board architectures, we produce illumination systems that set benchmarks for reliability, brightness, and lifetime efficiency.
How Ningbo DERT Lighting addresses complex systemic engineering challenges in modern passenger vehicles, commercial trucks, and off-road applications.
Automotive solid-state LEDs require strict junction temperature control to prevent thermal degradation. Our R&D division employs advanced fluid dynamics and thermal design using premium die-cast aluminum enclosures, heat pipes, and micro-fan cooling assemblies to ensure consistent light output and a prolonged operating life spanning over 50,000 hours.
We provide full-spectrum BGA PCB assembly (PCBA) for automotive lights. Our smart driver designs incorporate specialized microcontrollers that support CAN-bus communication, preventing dashboard error codes. They also feature over-voltage and transient voltage protection to guard against electrical spikes in the vehicle’s electrical grid.
As automotive manufacturers push for weight reduction to optimize electric vehicle range, our design team uses high-performance polycarbonates and optimized optical lenses. This approach allows us to reduce unit weight while maintaining superior structural strength and impact resistance, helping our clients reach their vehicle weight reduction targets.
The global automotive lighting sector is experiencing a major technological transition. Traditional halogen and HID systems are rapidly being phased out, replaced by energy-efficient LED and Adaptive Driving Beam (ADB) technologies. Regulatory bodies worldwide are raising road safety and environmental standards, making vehicle lighting compliance more crucial than ever.
At the same time, regional aftermarket demand fluctuates based on vehicle age, economic shifts, and environmental conditions. Our dual-channel manufacturing framework is designed to address these trends. We supply high-precision components directly to production lines while offering premium aftermarket upgrade kits that meet the strict requirements of international distributors.
To remain competitive on a global scale, DERT Lighting maintains absolute control over our entire supply chain. Our operations span from raw material sourcing and custom injection molding to direct component distribution.
Ensuring compliance with regional automotive standards and providing engineering assistance to streamline your product certification process.
For European and adjacent markets, we manufacture lighting components that meet UNECE regulations. Our products undergo third-party photometric audits to achieve required E-Mark approvals (such as E1, E4, or E9), covering beam patterns, luminous intensity, and color temperature.
We build our automotive lighting to meet the safety performance standards set by the Department of Transportation (DOT) and Federal Motor Vehicle Safety Standards (FMVSS 108) for North America. This ensures our headlights, signal markers, and work lights comply with the required light distribution patterns and environmental resilience criteria.
Operating under the rigorous IATF 16949 quality management framework, DERT ensures complete component traceability. We apply Advanced Product Quality Planning (APQP), perform Failure Mode and Effects Analysis (FMEA), and complete standard Production Part Approval Processes (PPAP) to meet the requirements of Tier-1 OEMs.
We tailor our products to perform reliably across diverse operational environments, varying climates, and specialized industry applications.
Heavy-duty long-haul transport requires durable side marker lights, trailer systems, and auxiliary lighting that can withstand constant vibration, moisture, and road debris.
Our off-road light bars and high-lumen work lights feature IP67 and IP69K ratings. They provide consistent illumination in dusty mining sites, agricultural areas, and rugged terrains.
Our honeycomb-shaped ceiling lighting systems are designed for high-end detailing garages, showrooms, and paint correction facilities, delivering uniform shadow-free lighting.
We supply direct-fit plug-and-play LED systems, Bi-LED projector lenses, and smart interior ambient lighting that integrate cleanly with original vehicle systems.
DERT Lighting is actively developing next-generation illumination technologies. Our engineering roadmaps focus on integrating optoelectronics with vehicle assistance systems to improve nighttime visibility and safety.
Key development areas include: Adaptive Driving Beam (ADB) matrix headlights that adjust lighting zones automatically to prevent glaring oncoming drivers, and 77GHz millimeter-wave radar integration for blind-spot detection and forward-collision warnings.
We are also working to optimize current draw and thermal performance for electric vehicle architectures, helping to maximize battery efficiency.
Every automotive lighting accessory we manufacture undergoes rigorous testing inside our quality control laboratories before shipment. This ensure performance and reliability in the most challenging operational environments:
Answers to technical questions commonly asked by automotive lighting distributors, procurement managers, and OEM project developers.
We design using high-thermal-conductivity metal-core PCBs (MCPCB), premium aluminum heat sinks, and thermal interface materials (TIM). For high-lumen applications like our 20,000lm work lights, we integrate active fan cooling alongside intelligent thermal foldback circuitry that automatically manages drive current to protect LEDs from overheating.
We offer complete OEM and ODM design services. Using our in-house tooling division, we can design custom plastic injection molds (including dual-shot molding) for lens and housing designs. We also provide customized PCB layouts, customized packaging, and laser-engraved product branding.
Yes, all of our digital driver assemblies incorporate EMC filtering to meet CISPR 25 and EU directive standards. This prevents high-frequency electrical noise from interfering with FM radio reception, GPS signals, Bluetooth connections, or nearby vehicle ADAS systems.
We use high-grade silicone sealing gaskets and dynamic venting systems featuring GORE® micro-porous membranes. These membranes allow air pressure to equalize within the housing as temperatures change, while preventing water droplets and dust from passing through, ensuring an IP67 or IP69K sealing rating.
