It fits directly into your headlight socket. There is no modification or rewiring need to your bike. Used in DC systems only.
Some machines require 2 headlight bulbs
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.
