This bulb is intended for a DC 12-volt system. It can function as low as 10-volts and as high as 16-volts. The voltage at the light socket, at full throttle, should not exceed 16-DC volts. If your machine has AC volts at the light socket this bulb will flicker and burn out. To get DC volts to your light socket you can wire the light directly to the battery or add a voltage regulator.

Please note: light bulbs are a part of an electrical system in a machine. 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.
