A stop lamp for a vehicle, such as a stop lamp adapted for mounting on a rear spoiler of an automobile, having an improved efficiency of light utilization. The lamp includes a lamp body, a front lens, and a plural number of light-emitting diodes juxtaposed at predetermined intervals. Light control parts are formed in the inner wall of the front lens for directing the light output from the light-emitting diodes in predetermined directions. Each light control part is composed of nine prisms arranged in a 3.times.3 matrix. The central one of the prisms faces a respective one of the light-emitting diodes.
