Description

When you’re working late into the night getting the harvest in or finishing up field work before a weather front moves in, you need those roof lights to work reliably. A failed work light relay can leave you working in the dark just when you need the illumination most. This 20-amp relay handles the heavy electrical load from your roof-mounted work lights while protecting your cab switches from burnout.

What You’re Getting

20-amp capacity handles multiple high-intensity work lights without voltage drops
4-pin design keeps the wiring simple and makes troubleshooting easier
Heavy-duty contacts resist the arcing that kills cheaper relays
Weather-resistant construction stands up to moisture and vibration
Direct replacement that plugs right into your existing electrical system

Built for Real Farm Work

This relay is designed for Ford New Holland TM series tractors—those reliable workhorses from 115 to 190 horsepower that handle everything from cultivating to harvest. These tractors often pull long days and night shifts during critical farming seasons, making dependable work lighting essential for safe operation around implements and three-point attachments.

Made to Last

Farm relays take a beating from constant vibration, temperature swings, and electrical stress. This relay uses quality electromagnetic switching that prevents contact welding and extends service life. The 20-amp rating provides plenty of capacity for your lighting load while preventing the overheating that destroys lighter-duty relays.

Good to Know

The relay typically mounts in your main fuse box or electrical panel. Installation is straightforward—disconnect the battery, pull the old relay, and plug in the new one. Always check your wiring diagram to verify pin assignments, and while you’re at it, check that all your work lights are actually functioning properly before blaming the relay.
