A horn for a vehicle is provided to facilitate implementation of the horn in the vehicle by enabling a user to easily discriminate positive and negative lines from each other. A horn for a vehicle includes a connector(100) which includes first to third lines. The lines are electrically connected to outside the vehicle. The first line is connected to a positive terminal of a vehicle battery. The second and third lines are exclusively connected to a positive terminal or a negative terminal of the vehicle battery. The second and third lines are electrically connected to each other. The horn includes a power supply(200), a switching unit(300), an alarm generator(400), and a controller(500). When the switching unit is turned on, the alarm generator generates an alarm sound by using the power from the positive terminal of the vehicle battery. The controller is activated by the power from the power supply and outputs a control signal to the alarm generator.
