Abstract
A motor vehicle headlamp of the closed type includes ventilation means for ventilating its inside volume, said means comprising at least one air inlet and one air outlet. According to the invention, the air outlet opens out into a hollow column that is disposed so as to have a substantial inclination relative to the horizontal. The top end of the column is closed. Along one of the outside walls of the column there is an elongate opening which opens out to the outside and which has a top end terminating at a certain distance from the closed top end of the column. Finally, the air outlet opens out into the column at a certain distance above the top end of the opening. This provides an air outlet associated with a device that ensures that extraction takes place adequately even when the vehicle is stationary, while nevertheless minimizing the risk of water penetrating into the headlamp, e.g. due to a cleaning jet.
