A vehicle lamp is configured to be able to selectively perform low-beam irradiation and high-beam irradiation. The vehicle lamp includes first and second light-emitting elements and a reflector for reflecting light emitted from these first and second light-emitting elements toward a front. A reflecting surface of the reflector has a first reflection region on which light emitted from the first light-emitting element is incident and a second reflection region on which light emitted from the first light-emitting element is not incident but light emitted from the second light-emitting element is incident. A low-beam light distribution pattern having horizontal and oblique cutoff lines is formed by turning on the first light-emitting element. A high-beam light distribution pattern is formed by turning on the second light-emitting element or simultaneously turning on the first and second light-emitting elements.
