When you’re adding LED work lights to your tractor or implement, you need more than just the lights – you need the right wiring to power them safely and reliably. This 9.9-foot harness takes the guesswork out of wiring by including everything you need: relay, on/off switch, and waterproof connections. No more figuring out amp ratings or hunting for the right relay – this kit handles it all so you can focus on lighting up your work area.

What You’re Getting

  • Pre-wired relay and switch eliminate the need to source separate electrical components
  • 9.9-foot length provides flexibility for routing around frames and implements
  • 12V-32V compatibility works with standard tractor systems and newer equipment with higher voltage
  • IP67 waterproof rating keeps connections sealed against pressure washing and field conditions
  • Ready-to-connect design saves time compared to building your own harness from scratch

Built for Real Farm Work

This universal harness is perfect for adding LED light bars to tractors, mounting work lights on implements like sprayers or planters, or upgrading older equipment with modern LED lighting. The wide voltage range means it works whether you’re wiring up a compact utility tractor or a high-horsepower machine with 24V or 32V electrical systems.

Made to Last

The fully waterproof design means power washing your equipment won’t leave you with electrical problems. The relay and connections are built to handle the vibration, dust, and temperature extremes that come with agricultural use.

Installation Notes

Connect the power wire to a fused circuit, mount the relay in a protected location, and run the switch wire to wherever you want convenient control – many folks put it right on the dashboard. Don’t forget an inline fuse for safety. The waterproof connectors make hookup simple, and the included relay handles the heavy current so your switch only carries the control signal.
