Description
If you’ve got one of those classic tractors from the ’60s or ’70s, you know that finding the right headlight bulb can be a real headache. Standard automotive bulbs just don’t fit the old-style double contact pre-focus sockets, and you need both high and low beam in one reliable unit. This 12V 50/40W dual filament bulb is built specifically for older farm equipment with traditional headlight assemblies.
What You’re Getting
- Dual filament design gives you 50 watts for high beam and 40 watts for low beam in one bulb
- Pre-focus base design means proper beam alignment every time—no adjustments needed
- Double contact connection provides secure electrical contact that won’t vibrate loose
- Heavy-duty filament construction handles the constant vibration of field work
- Clear glass maximizes light output for better visibility during long working days
Built for Real Farm Work
This bulb fits those traditional headlight housings you’ll find on vintage tractors from the major brands. Whether you’re running an old Ford, International, John Deere, or any classic farm tractor, this is the type of bulb that came from the factory. These are the tractors that built farms across America—utility machines that are still earning their keep doing loader work, mowing, and the hundred other jobs that keep a farm running.
Made to Last
Farm equipment lighting takes a beating from constant vibration, temperature swings, and dust that gets into everything. This bulb’s robust filament design is engineered to handle those demanding agricultural conditions while providing consistent light output season after season.
Installation Notes
This is a direct replacement for original equipment bulbs in vintage tractor headlight assemblies. Handle the bulb by its base only to avoid getting oils from your skin on the glass, which can cause hot spots and premature failure. A good tip: clean the headlight housing and check your electrical connections while you’ve got everything apart.
