40-Amp Work Light Relay for Ford New Holland 40, 60, TM, TS, and Fiat M Series Tractors

Description

When you’re working past sunset or starting before dawn, having your work lights cut out isn’t just frustrating—it can be dangerous. If your roof lights have been acting up, going dim, or not coming on at all, this 40-amp relay is often the simple fix that gets you back to productive work in low-light conditions. This heavy-duty relay handles the electrical load from multiple high-intensity work lights while protecting your cab switches from burning out.

What You’re Getting

• 40-amp capacity handles heavy electrical loads from multiple high-wattage work lights without voltage drops
• 4-pin design provides reliable switching with separate power, ground, control, and load circuits
• Heavy-duty electromagnetic contacts withstand frequent switching and resist contact welding
• Weather-resistant construction keeps moisture and dust out of the switching mechanism
• Direct replacement design plugs right into your existing electrical panel

Built for Real Farm Work

This relay serves the workhorses of many farming operations—Ford New Holland 40 Series utility tractors, 60 Series row-crop machines, TM Series high-horsepower tractors, TS Series mid-range models, and Fiat M Series tractors. These machines often run long hours during critical seasons, and reliable roof lighting is essential for safe operation during night cultivation, late-season harvesting, and loader work around buildings.

Made to Last

Farm equipment electrical systems take a beating from vibration, temperature swings, and heavy electrical loads. This relay is built with quality electromagnetic switching that prevents the contact damage that kills cheaper relays. The 40-amp rating provides plenty of headroom for your lighting circuit without the overheating that causes intermittent failures.

Good to Know

This relay typically mounts in your main electrical panel or fuse box and connects to your lighting switches through existing wiring. Installation is straightforward—just unplug the old relay and plug in the new one. Always disconnect battery power before working on electrical systems, and if you’re having lighting problems, check your fuses and ground connections first before replacing the relay.
