Abstract
A headlight for motor vehicles is provided with a unit for preventing fog formation on the internal walls of the headlight or its reflector. The unit can be interchangeable and includes an inlet valve for admitting air into the interior of the reflector when underpressure prevails in said interior and an overpressure-responsive outlet valve which permits air to flow out from said interior into the atmosphere when overpressure occurs in the interior of the reflector. The unit is filled with drying agent for adsorbing moisture from the passing air.
