Nothing ruins a late evening in the field like a burned-out headlight. Whether you’re finishing up harvest, moving equipment after dark, or dealing with early winter days, you need reliable lighting to work safely. This 4-1/2 inch sealed beam bulb gives you the bright, dependable illumination your tractor was designed to deliver.
What You’re Getting
- True 12-volt sealed beam design that handles vibration and weather without flickering
- Standard 4-1/2 inch diameter fits directly into existing lamp housings
- Durable glass construction resists cracking from stone chips and temperature changes
- Reliable filament design provides consistent light output season after season
- Direct replacement for original equipment—no modifications needed
Built for Real Farm Work
This bulb works in a variety of John Deere tractors including the 870, 970, and 1070 models, fitting lamp numbers L408, L505, L610, and L810. It’s also the right choice for Massey Ferguson tractors that use 12-volt, 4-1/2 inch sealed beam headlights. These are the workhorses that put in long days during planting and harvest when every hour of daylight counts.
Made to Last
Farm equipment lighting takes a beating from constant vibration, temperature swings, and flying debris. This TISCO bulb is built to handle those conditions with a robust sealed beam construction that keeps moisture and dirt out of the critical components. The heavy-duty filament design means you’ll get reliable service even when bouncing across rough fields.
Good to Know
Installation is straightforward—just remove the old bulb from the lamp housing and plug in the new one. Make sure the electrical connections are clean and tight for the best performance. It’s smart to keep a spare bulb on hand since headlights always seem to burn out at the worst possible moment, usually when you’re miles from the shop.
