Abstract
Disclosed is a vehicular lamp in which a closed lamp chamber is defined by a lamp body and a front lens, a reflector with a light source attached thereto is disposed apart from the lamp body, and air holes, which are used for the breathing action of the lamp, are formed in the portions of the lamp body located above and below the light source. The vehicular lamp is improved such that a horizontal rib is located inside the lamp body or outside the reflector to block a vertical air stream flowing through a gap between the rear side of the front lens and the lamp body, whereby the amount of air going out and coming in through the air holes is increased (the breathing action is activated) and the dew-formation preventing effect is enhanced.
