Abstract: A headlight is disclosed. The headlight comprises: a light-guiding unit, the inner surface of the front surface of the light-guiding unit being coated with a totally-reflecting material; at least one light-emitting device fixed to the inner surface of the side surface of the light-guiding unit; a power supply unit for supplying power to each light-emitting device; at least one prism arranged on the inner surface of the rear surface of the light-guiding unit so as to reflect light from each light-emitting device; and a control unit for controlling power of the power supply unit, wherein light emitted from the light-emitting device is reflected at the prism and at the inner surface of the front surface and is discharged to the outside of the light-guiding unit. Accordingly, the device usability and efficiency can be improved.
