These bulbs are custom made with a front projection lens, the beam angle is 360 degrees, they have a steel base and an alloy body. They are one of the brightest bulbs in their class; over 600-700% brighter than a standard bulb! However, it is the front projections that makes them so effective. They're just a better engineered than other bulbs.

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 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.
