Anti-fogging structure for vehicle headlights

Conforming with the differing conditions in which the left (5L) and right (5R) headlight lamps are placed, an anti-fogging structure for headlight lamps is proposed wherein variation in the anti-fogging performance on the left and right does not occur by providing differing structures for the breathing mechanisms in the left and right headlight lamps. In an anti-fogging mechanism for headlight lamps (5L and 5R) provided on the left and right of the radiator fan (6) at the front of the body of a vehicle, different structures are provided for the breathing holes (10,11,12) that enable circulation of air into and out of the lamp housings (51L and 51R) of the left and right headlight lamps (5L and 5R).
