Abstract: A vehicular lamp having an air vent structure of reduced size and with which the airtightness of a lamp housing can easily be tested. An integrally formed tubular wall projects rearward from a rear wall of a lamp body. The rear edge of the tubular wall is inclined downward in a forward direction, and its outward edge lies in a single plane inclined downward in the forward direction. A communicating hole through which the interior and exterior of a lamp housing are communicated is formed in a portion of the rear wall which is surrounded by the tubular wall.

Abstract: An automobile signal lamp being mounted on the inside of a rear window of an automobile and including a lens member, a body member and a light source member which is disposed in a space defined between the lens member and the body member. Connecting portions are integrally formed on respective lens member and the body member, and which portions cooperate in connecting the lens member with the body member.

Abstract: An automobile lamp of the type including a light source, a lens member and an inner lens member disposed between the light source and the lens member. A mounting portion is integrally formed on the inner lens member, a stepped portion is formed on the lens member, and an edge of the mounting portion is secured to the stepped portion by ultrasonic welding.

Abstract: 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.

Abstract: A vehicle lamp device in which the inside of a lamp unit is communicated with the outside while maintaining a water-proof property of the lamp unit itself so that generation of water droplets is prevented. The lamp unit constituted by a lamp body for housing a large number of light-emitting diodes arranged at predetermined intervals in a transverse direction of a vehicle body and a front face lens covering a front opening portion of the lamp body incorporated in a spoiler disposed on an upper surface of a rear end portion of a roof of the vehicle body so that the front face lens is exposed to the outside through an opening portion formed in a rear end surface of the spoiler. A rubber bushing is disposed in the spoiler, and lead wires of the lamp unit are led out to the outside of the lamp unit through a lead-out portion which projects from a back surface of the lamp body and are inserted through lead-wire insertion holes formed in the rubber bushing.
