Abstract
A vehicular lamp equipped with an extension for covering a gap formed between a lamp body and a reflector. To improve air circulation, the extension includes a lower frame portion which has openings for communicating the area proximate the inner face of the lens with a back area of the extension. The openings are located at left and right positions of the frame portion, respectively. Furthermore, venting holes for communicating between the inside and outside of the lamp body are formed in the lamp body at positions opposed to the openings, and a shroud for introducing air flow along the inner face of the lamp body extends between the venting holes and the openings. The openings ensure a sufficient amount of air flow in the vicinity of the inner face of the lens. Thus, it is possible to prevent the inner face of the lens from becoming misted due to dew condensation.
