Vehicle Lighting System

Vehicle Lighting System

In automotive lighting systems, relays function as critical protection switches. Lighting wire harnesses are designed with compatible connectors to ensure reliable performance in harsh environments.

Medical Surgical Lighting

Medical Surgical Lighting

Surgical lighting systems—available in mobile, wall-mounted, and ceiling-mounted configurations—are essential in medical environments. As cold light sources, they must deliver low heat output, deep illumination, and accurate color rendering. Reliable wiring harnesses support critical safety functions such as overheat protection and voltage surge protection.

Road+Outdoor

Road & Outdoor Lighting

Outdoor wiring harnesses must deliver robust performance in harsh environments. They are engineered with UV-resistant insulation, sealed connectors, and durable materials to withstand rain, temperature extremes, and prolonged exposure. At the same time, they maintain flexibility and integrate protection features such as fuses and relays to prevent short circuits and overloads.

Frequently Asked Questions

Customers choose WIRES not only for the value we deliver, but also for our responsive and detailed support. Here are some of the frequently asked questions we’ve compiled.
What components make up a custom lighting wire harness?

The components of a custom lighting wire harness vary based on application requirements and operating environments.

For commercial lighting systems (e.g., office and architectural lighting), harnesses are typically designed with simplified structures, focusing on cost efficiency and easy installation, often using basic wiring and standard connectors.

For automotive and industrial lighting applications, harnesses are more complex and typically include:

  • Terminals and connectors (IP65–IP67 rated options available)
  • Insulation and protective sleeving (PVC, PE, or high-temperature materials)
  • Fastening and routing components for secure installation
  • Optional shielding and protection devices to enhance durability and safety

WIRES has delivered 50,000+ custom lighting wire harnesses across automotive, industrial, and outdoor applications, with support for low-volume prototyping and high-volume production.
