1 set of 3 new SUPER bright high-quality headlight bulbs for Deere 318, 322, 332, 420, 430, 655, 755, 855, 955, and others, AND 1 set of 2 new SUPER bright high-quality taillight bulbs. They fit directly into your tractor's light sockets. Just plug them in. No modification or fabrication to your tractor. It's as easy as changing a light bulb. They are about 400% brighter than a traditional bulb, which is super bright.
They are much brighter, lasts longer (about 50,000 hours), uses less watts, and do not get hot and will not melt your lens or burn your wires.
Please note: light bulbs are a part of an electrical system in a tractor. For bulbs to function properly components such as electrical system, stator, voltage regulator, and light bulb sockets need to be fully functional. Common malfunctions in tractors are: Loose ground wire, bare positive wire causing a short, poor contact between the bulb and light socket, and malfunctioning voltage regulator which would cause high DC voltage or AC voltage getting into the wiring harness and blowing bulbs instantly.
