1. A vehicular lamp comprising:
a light source;
a glass disposed ahead of the light source;
a housing configured to support the light source and the glass and form an appearance;
a thermoelectric element unit disposed at a lower end of an external rear surface of the housing and configured to generate cold wind and hot wind by introducing external air of the housing;
a first flow path introducing one of the cold wind and the hot wind generated by the thermoelectric element unit into the housing; and
a second flow path discharging the other one of the cold wind and the hot wind to outside of the housing,
wherein the thermoelectric element unit comprises:
a first part connected to the first flow path and generating one of the cold air and the hot air;
a second part connected to the second flow path and generating the other one of the cold air and the hot air;
a body part dividing a space where the first part and the second part are disposed and having an opening formed in a bottom surface thereof; and
a first fan disposed at the opening of the body part and introducing air in a direction from a lower portion to an upper portion,
wherein the vehicular lamp further comprises:
an air blowing port disposed at an upper end of the rear surface of the housing;
a second fan disposed inside the housing and causing circulation of the air introduced into the first flow path;
a fan housing disposed at a front side of a bottom surface of the housing to support the second fan; and
a reflector for reflecting light of the light source toward the glass in the housing,
wherein the second part is disposed below the first part, the first fan is disposed in parallel with the bottom surface of the body part, and the body part guides air introduced from an opening into the first part,
wherein the fan housing sucks in air through a first opening formed in a direction toward a rear surface and discharges air through a second opening formed in a direction toward an upper surface, and
wherein an inlet for discharging air from the first flow path into the housing is disposed ahead of the reflector.
