Our Amazing Clients
Different vehicles utilize distinct lighting systems, such as headlights, turn signals, brake lights, and ambient lighting. Similarly, wiring harnesses are required for road, residential, tunnel, and medical lighting applications. All lighting systems require precise wiring harness connections to ensure the reliable operation of LED lights, halogen bulbs, and other types of lighting fixtures. As a professional wiring harness manufacturer, JinHai leverages its robust manufacturing expertise and stringent quality control to design, manufacture, and assemble lighting harnesses for these diverse applications.
Lighting Harnesses Applications
JinHai can produce lighting harnesses for the following fields:
Vehicle Lighting System
In vehicle lighting systems, relays serve as critical protective switches. Lighting harnesses must be equipped with connectors compatible with such electronic components to withstand harsh external environments.
Medical Surgical Lighting
Surgical lights are the most common lighting fixtures in medical surgical settings, categorized into mobile, wall-mounted, and ceiling-mounted types. As a type of cold light source, surgical lights should emit minimal heat while maintaining sufficient depth of field and accurate color rendering. Therefore, overheat protection and voltage spike protection are core safety features.
Road/Outdoor
Exposed wiring harnesses installed outdoors must possess robust core functionality. Insulation layers and connectors must be sufficiently sturdy and hermetically sealed to withstand environmental conditions such as UV radiation, rainfall, and extreme temperatures. Simultaneously, they should maintain adequate flexibility and incorporate safety devices like fuses or relays to prevent short circuits or overloads.
