Built for Real Farm Work
This versatile bulb shows up everywhere on your tractor – brake lights that warn following traffic when you’re slowing for that field entrance, turn signals that clearly show your intentions with wide implements, and amber warning lights for slow-moving equipment. Whether you’re running a compact utility tractor or a big row crop machine, chances are you’ve got several of these 21-watt workhorses keeping you visible and legal.
Made to Last
Agricultural equipment takes a beating, and lighting is no exception. The 21-watt output provides excellent visibility without stressing your charging system, while the robust filament design handles the constant vibration, temperature swings, and dust that come with farm work. The in-line pin configuration is one of the most common in agricultural equipment, making this bulb a smart choice for shops servicing mixed fleets.
Good to Know
At this price, keeping spares in your toolbox just makes sense – bulbs always seem to fail at the worst possible moment. Always check both contacts are making good connection, and clean socket contacts with fine sandpaper if corroded. Handle bulbs with clean hands or cloth since oil from fingers can create hot spots that shorten bulb life. When one bulb fails, check its mate on the other side – they’ve seen the same hours and often fail close together.
