In the modern automotive landscape, safety and signaling are no longer just functional requirements—they are integrated components of vehicle intelligence. As a leading CE Certified Automotive Position Lights Factory & Supplier, we recognize that "Position Lights" (often referred to as clearance lamps or side marker lights) serve as the vital visual boundaries of a vehicle, ensuring its presence, orientation, and width are clearly communicated to other road users in low-visibility conditions.
Unlike standard illumination, position lights require precise photometric distribution. Our engineering team focuses on maximizing the "Information Gain" for drivers—providing clearer, faster visual recognition through optimized LED wavelength consistency and refractive lens technology. Whether for passenger cars, heavy-duty trucks, or specialized forklifts, our lighting systems are designed to exceed ECE R7 and SAE J222 standards, offering unparalleled reliability in extreme environments.
Established in 2012, Ningbo DERT Lighting Co., Ltd. is a professional manufacturer specializing in automotive lighting systems, LED headlights, and vehicle lighting solutions for global automotive aftermarket and OEM customers. Located in Ningbo, Zhejiang Province, China, the company operates a modern production facility covering approximately 18,000 square meters and employs more than 320 skilled professionals across engineering, manufacturing, quality assurance, research and development, and international sales departments.

DERT Lighting focuses on the design, development, and production of automotive lighting products, including LED headlight systems, vehicle lighting assemblies, signal lighting solutions, commercial vehicle lighting products, off-road lighting systems, and customized automotive illumination technologies. Supported by an experienced engineering team, we continuously invest in product innovation, optical design, thermal management technologies, and manufacturing automation.
We provide rapid prototyping with precision tolerances of 0.01-0.05mm. Our custom CNC machining for PMMA automobile headlamps ensures optical clarity and perfect fitment before mass production.
Integrated service for high-quality car lamp mould processing. We manage the entire lifecycle from design to export, ensuring structural integrity and durability.
Using 6063 Aluminum and active cooling systems, our LED products maintain optimal performance even in high-wattage (35W-145W) applications, preventing lumen depreciation.
Pioneering Bluetooth and App-controlled lighting systems, allowing for customizable RGB colors, "Devil Eye" effects, and programmable animation sequences for vehicle styling.
Rigorous testing for dust and water ingress protection. Our lights are built for RVs, marine environments, and heavy-duty mechanical equipment where exposure is constant.
For European and international buyers, CE Certification is not just a legal requirement—it is a mark of reliability. It ensures that the position lights comply with EMC (Electromagnetic Compatibility) directives, meaning they won't interfere with the vehicle's sensitive electronic control units (ECU) or ADAS systems.
The industry is shifting toward "Smart Signaling." Procurement teams are now looking for position lights that offer more than just a steady glow. Key trends include:
Clearance lamps for trucks and trailers that withstand high-vibration environments and extreme weather across trans-continental routes.
Dual-color camping lights and chassis-integrated signaling for heavy-duty motorhomes, ensuring safety in remote off-grid locations.
Beacon lights and waterproof metal indicators for forklifts and mechanical equipment, where visibility is a critical safety protocol.
High-power LED headlamps and "Smart Eye" screens for enthusiasts looking for OEM+ quality and modern digital interfaces.
Typically, sample prototyping via CNC or 3D printing takes 7-10 days. Mass production for custom moulds takes 25-35 days depending on complexity.
We use a multi-stage quality management process including 48-hour burn-in tests, optical sphere lumen verification, and thermal imaging to ensure heat dissipation is within safe limits.
Yes, we manufacture products specifically tailored to North American (DOT/SAE) and European (ECE/CE) regulatory standards to ensure legal compliance in your local market.
Absolutely. We offer integrated services from mould design and production to final product injection, supported by our 18,000 sqm facility in Ningbo.
