Premium SAE 12V Combination Tail Light Harness Kit

Durable 16-gauge copper wiring with abrasion-resistant PVC insulation ensures optimal conductivity and long-term reliability in harsh environments. Precision-molded 7-pin connectors feature gold-plated terminals for corrosion resistance and secure plug-and-play installation.

Universal Compatibility for Heavy-Duty Applications

Engineered to seamlessly integrate with trucks, trailers, boats, and RVs—supports LED/incandescent lighting systems including side markers, brake lights, and turn signals. OEM-grade heat shrink tubing protects solder joints from moisture and vibration.

Commercial-Grade Construction

Industrial-strength nylon casing withstands extreme temperatures (-40°F to 185°F) while crush-resistant wire loom prevents damage from road debris. Pre-wired with clearly labeled circuits for error-free hookup under DOT/SAE standards.

Optimized for Fleet Maintenance

Bulk packaging available for logistics companies and repair shops—pre-tested assemblies reduce installation time by 70% compared to handmade harnesses. Backed by 10-year waterproof warranty.

Note: Kit includes 7-way junction box with integrated ground wire—no additional adapters required for most North American trailers.
