PROBLEM TO BE SOLVED: To provide a headlight for vehicle, which can restrain the occurrence of dim and dew condensation of the inner surface of a lens at the minimum. SOLUTION: A pair of air holes 54, 56 are formed in a lower part of a rear surface 12b of a body 12 near both side ends thereof, and an air hole 58 is formed in an upper part of an intermediate part between the air holes 54, 56. When temperature of bulbs 24, 36, 28 is raised by lighting of a headlight 10, a convection is generated inside of a lamp body. At this stage, the air warmed in the lamp body is discharged from the air hole 58, and while the outside air is led into the lamp body through the pair of air holes 54, 56 so as to improve the ventilation of corner parts in a lower part of both side ends, in which dim and dew condensation of the inner surface of a lens occur the most easily in the lamp body. |
