Abstract
Disclosed is a vehicular lamp in which a closed lamp chamber is defined by a lamp body and a front lens, a bulb is disposed within the lamp chamber, and air holes for breathing action are formed in the rear wall of the lamp body. In the vehicular lamp, the air holes are elongated in shape, whereby the air holes each having a large diameter may be formed at desired positions of the rear wall of the lamp body where the air holes do not interfere with various members and components, such as the bulb-exchange opening, the aiming mechanism and the mounting bracket. With the structure, an air circulates within the lamp chamber in such a mode as to prevent moisture from being condensed on the front lens.
