Explore our high-performance solutions designed for durability, strict electrical compliance, and superior optical focus.
Established in 2012, Ningbo DERT Lighting Co., Ltd. has grown to become a cornerstone manufacturer specializing in automotive lighting systems, LED headlights, and custom vehicle lighting solutions. Catering directly to global automotive aftermarket distributors, Tier-1 suppliers, and OEM vehicle builders, we ensure our production standards exceed conventional limitations.
Located in the vital port city of Ningbo, Zhejiang Province, China, our company operates a modern, state-of-the-art production facility spanning approximately 18,000 square meters. We employ over 320 skilled professionals spanning R&D optical engineering, thermal simulation specialists, quality control teams, and international logistics experts.
"Through continuous investment in automated assembly and high-efficiency SMT lines, DERT Lighting integrates advanced thermal structures with precise optical focus to deliver zero-defect lighting modules worldwide."
Our focus covers the entire spectrum of modern vehicle illumination: from direct-fit OEM replacement headlights for high-end luxury passenger cars to heavy-duty off-road lighting setups and complex specialized medical shadowless lights. Leveraging our robust internal injection molding and precision CNC processing capabilities, we bring bespoke product drafts to life rapidly and cost-effectively.
The automotive lighting paradigm has evolved from basic safety devices to smart, sensor-integrated communication systems. Discover where we are heading.
Integrating multi-pixel array chips with real-time camera inputs. Our systems dynamically switch off individual LED pixels to prevent blinding oncoming traffic while keeping the remainder of the road brightly lit. This reduces nighttime accident risk by up to 30% compared to static high beams.
Pioneering laser-excited phosphor modules that project focused light beams up to 600 meters. These systems maintain exceptional light quality with half the power consumption of standard LEDs, enabling higher speed safety profiles for high-end autonomous and electric passenger vehicles.
Leveraging Digital Microlens Arrays (MLA) and Digital Light Processing (DLP) projection, we design headlamps capable of displaying directional navigation arrows, pedestrian crosswalk alerts, and lane safety indicators directly onto the road surface ahead, linking safety to ADAS sensors.
From rugged industrial work sites to specialized surgical operating theaters, we engineer customized lighting arrays suited to precise Lux and CRI requirements.
Bespoke headlights engineered to comply with strict ECE and FMVSS regulations. Includes custom thermal pathways using copper core PCBs to extend the operational lifetime of LED modules to 50,000 hours.
Engineered to withstand continuous vibration and extreme mechanical shocks. Ideal for commercial trucks, excavators, tractors, harvesters, and off-road emergency vehicles running on 12V/24V electrical architectures.
Extending our optical capabilities to surgical environments. Integrating custom multi-lens structures that prevent shadow formation during medical operations, achieving ultra-high color rendering indexes (CRI > 96).
Operating out of Ningbo, China, DERT Lighting takes advantage of the world’s most robust automotive electronics supply chain cluster. This physical proximity allows us to source premium materials, high-density chips, and micro-switches under shortened lead times, which in turn benefits our global clients through pricing flexibility and supply security.
Our facility incorporates automated SMT positioning machines, automated optical inspection (AOI) units, and automated plastic injection lines. By standardizing manufacturing flows, we keep defect rates below 150 PPM (Parts Per Million), far below the industry average for aftermarket automotive components.

We design with localization in mind. Different markets require specific light beam cutoff angles, coloring metrics, and electronic interference suppression.
All European headlight replacements must feature sharp cut-off lines to prevent glare. We align designs to comply with ECE R112 (Headlamps), R37 (Filaments), and R10 (Electromagnetic compatibility), easing the path for European E-mark approvals.
North American vehicle regulations require specific photometrics and amber side reflectors. Our lighting assemblies incorporate compliant reflectors and beam patterns, satisfying DOT and SAE standards for direct road legality.
Our off-road and utility lighting lines undergo rigorous thermal cycling (-40°C to +85°C), long-term vibration testing, and water immersion challenges to secure verified IP67, IP68, and IP69K ratings.
Managing procurement risks goes beyond comparing component prices. We support global sourcing managers through structural reliability, transparent timelines, and financial security.
Procuring from DERT Lighting offers strategic operational advantages designed to lower total cost of ownership (TCO) and mitigate supply chain disruptions:
From initial blue-light 3D modeling, PMMA lens prototyping, to final industrial tooling, we offer rapid milestones to shrink the time-to-market window for new vehicle designs.
We maintain full transparency, welcoming external third-party inspections (SGS, TUV) and supporting comprehensive factory audits by automotive OEM procurement divisions.
Being situated in Ningbo puts our operations adjacent to the Ningbo-Zhoushan Port, the largest port in cargo throughput. This minimizes inland shipping costs and shortens transit times.
Get answers to critical technical and manufacturing queries relative to advanced vehicle lighting systems.
High-power LED chips (such as S16 80W and custom 100W setups) create intense heat concentrated within a very small junction area. If this heat isn't effectively dispersed, junction temperatures will spike, triggering rapid lumen decay or thermal failure. At DERT Lighting, we resolve this by utilizing high-conductivity copper core PCBs, aircraft-grade dual-profile aluminum housings, and integrated dual-bearing silent cooling fans spinning up to 10,000 RPM. We also integrate an active thermal protection IC on the control board to dynamically adjust current if operating temperatures exceed safe limits.
Modern vehicles use ECU modules to continuously verify that lighting filaments are intact by measuring current draw. Since LEDs draw less power than traditional halogen bulbs, the ECU may flag this as a burnt-out bulb, producing dashboard errors or light flickering. Our LED drivers incorporate advanced CAN-bus decoding chips that simulate the correct electrical load characteristics. This ensures compatibility with complex CAN-bus systems without requiring external load resistors.
Injection molds for headlight lenses are expensive and require several weeks to fabricate. To mitigate development risks, our rapid CNC machining division crafts highly precise mock-ups using acrylic (PMMA) or ABS materials. This enables engineering teams to check mechanical fitment, lens clarity, and test basic optical light patterns before investing in tooling. This optimization shortens overall ODM project timelines by weeks.
High-power switching drivers in LEDs can emit electromagnetic waves, introducing noise into other vehicle electronics. To prevent this, we design our driver circuits to align with CISPR 25 Class 5 guidelines. This involves embedding high-grade EMI filters, shielding cables, and choosing components that damp high-frequency harmonics, ensuring safe operation alongside ADAS radars, blind-spot detectors, and entertainment units.
Yes. Our off-road driving lights (such as our 9-inch 80W and 4-inch 162W lines) feature wide-voltage input circuits (9V-32V DC). This enables reliable operation under fluctuating voltages typical of commercial trucks, tractors, and excavators, protecting the LEDs from voltage spikes.
