A vehicular lamp employing light-emitting diodes providing a good illumination efficiency, and which can be readily mounted on many different types of vehicles. The lamp includes a plurality of light-emitting diodes arranged on a supporting board, condenser lenses provided in front of each of the light-emitting diodes, and diffusion lenses arranged in front of the condenser lenses. A housing member supports the supporting board, the condenser lenses, and the diffusion lenses, the housing member having air holes formed therein to provide for ventilation. With this arrangement, the light produced by the light-emitting diodes is applied in the form of parallel beams to the front lens member by the condenser lenses, and the parallel light beams are diffused by the diffusion lenses on the front lens member. Accordingly, the front surface of the front lens member is illuminated in its entirety and illuminated uniformly.
