Maximum Power for Dual Light Bar Setups

When your off-road build requires serious illumination, the Diode Dynamics Heavy Duty Dual Output Wiring Harness provides the power you need. This harness is capable of powering two Diode Dynamics light bars (18 to 50 inches) simultaneously, making it the ideal choice for roof-mounted bars and bumper-mounted setups. Built to withstand the rigors of off-road use, this harness ensures your lighting system is both powerful and reliable.

Built for Performance

  • 14AWG Heavy-Gauge Wiring: Designed to handle the high current draw of large LED light bars safely.
  • Dual Deutsch DT Connectors: Weather-sealed for long-term reliability in mud, water, and dust.
  • Protective Sheathing: High-quality black wire sheathing prevents damage from engine heat and rubbing.
  • Advanced Safety: Includes a 25A waterproof fuse and a 60-amp 12V relay to prevent system overload.

This harness eliminates the need for multiple wiring runs, keeping your engine bay clean and organized. By providing a dedicated power path directly from the battery, you minimize voltage drop, allowing your lights to reach their full potential. Whether you are building a dedicated trail rig or a high-performance adventure vehicle, trust the quality of Diode Dynamics and the expert service at GGCRACING.
