A vehicle light can include a reflector and a light source. The reflector has a reflection surface formed by at least part of a parabolic cylindrical surface obtained by moving a parabola by parallel displacement, where the parabola has a coefficient of 0.5, a focal length, and a focal point. The light source includes at least one set of at least two light emitting devices that have respective light emission surfaces facing toward the reflection surface. The at least two light emitting devices include a front light emitting device and a rear light emitting device spaced apart by a predetermined distance along an illumination direction of the vehicle light, with the focal point interposed between the front and rear light emitting devices.
