Key Features & Performance Advantages


Automotive-grade Power Transmission & Lighting Stability

Our automotive light system wire harness uses high-purity oxygen-free pure copper conductors, delivering ultra-low resistance and stable power transmission, which is essential for consistent brightness and reliable operation of vehicle lighting systems. The precision-engineered structure minimizes voltage drop, ensuring stable performance of headlights, taillights, turn signals, and interior lighting, even during long-term high-load operation.


Superior On-road Environmental Adaptability

Designed for the harsh conditions of automotive operation, our IP67 waterproof automotive wiring harness offers exceptional all-round protection. It features industry-leading vibration resistance, wide-range temperature tolerance, oil and corrosion resistance, and anti-UV performance, perfectly adapting to the complex on-road environment of commercial vehicles and passenger cars. The IP67+ waterproof rating effectively prevents dust, rain, and road debris ingress, reducing lighting system failures and aftermarket maintenance costs for vehicle manufacturers.


Long-term Durability & Vehicle-specific Design

Every truck bus SUV lighting cable assembly is engineered for a service life matching the vehicle’s full lifecycle. We use automotive-grade wear-resistant insulation materials to prevent short circuits and insulation aging, while the optimized wiring layout ensures perfect fitment with the vehicle’s body structure, avoiding friction damage during vehicle operation. This design significantly reduces the risk of lighting system failures, improving vehicle safety and reducing after-sales service pressure.
