Product Overview
This harness integrates advanced materials and precision craftsmanship to ensure stable power transmission, strong environmental adaptability, and seamless compatibility with new energy vehicle (NEV) electrical architectures. What sets it apart is our industry-leading three-day proofing service, allowing clients to validate product fit and performance in record time—accelerating project development and market launch. Whether for electric vehicles (EVs) or plug-in hybrid electric vehicles (PHEVs), this harness delivers reliable support for LED lighting applications.
Key Features
LED-Optimized Power Transmission
Tailored for LED lighting systems (e.g., headlights, taillights, interior lights), the harness minimizes voltage drop and signal interference, ensuring consistent brightness and longevity of LED components. High-conductivity materials guarantee efficient energy transfer, aligning with NEVs’ energy-saving requirements.
New Energy Automobile Compatibility
Engineered to match the unique electrical specifications of NEVs (12V-48V DC), the harness works seamlessly with battery management systems (BMS) and on-board power units. It withstands the high-voltage, high-current operating environments of new energy vehicles.
Three-Day Rapid Proofing
Our streamlined proofing process enables sample delivery within 72 hours of requirement confirmation. Significantly reducing development cycles for clients in fast-paced automotive industries.
Robust Environmental Protection
Equipped with EMI/RFI shielding, heat-resistant XLPE insulation, and IP67 waterproof coating, the harness resists moisture, dust, extreme temperatures (-40℃ to 125℃), and electromagnetic interference—ideal for under-hood, exterior, and interior automotive environments.
Precision Manufacturing Standards
Automated crimping and soldering processes ensure uniform connection quality, eliminating loose contacts and short-circuit risks. Each harness undergoes 100% pre-delivery testing to meet strict performance criteria.

Customization Service Process
Clients provide details such as LED light type, NEV model, voltage requirements, length, connector preferences, and environmental operating conditions. Our technical team offers one-on-one consultation to refine specifications.
Based on client needs, we design a tailored harness solution (including material selection, shielding configuration, and connector matching) and provide a transparent quotation within 24 hours.
Upon order confirmation, our automated production line initiates sample manufacturing. We prioritize proofing for LED-NEV harnesses to ensure delivery within 3 working days.
Clients test the sample for fit, performance, and compatibility. We adjust designs promptly based on feedback (e.g., length modification, connector replacement)
After sample approval, we scale to mass production with strict quality control. Delivery options include express shipping for urgent orders.
We provide detailed installation manuals and technical support to ensure seamless integration of the harness into NEV LED systems.
