Durable construction that stands up to real-world use

Extended length for versatile applications

• 25 feet of male 4-flat wire plus 2.5 feet of ground wire provide ample reach for many trailer layouts.

Reliability and safety on the road

This harness is designed to help maintain a stable electrical connection, supporting visibility and safer operation during travel. While performance will depend on your specific setup and maintenance, the kit aims to offer a solid foundation for trailer lighting needs.
