A solvent medium is taken up by the air through ejector effect. The compressed air is activated by the vehicle brake system and flows outwards from the blow-out mouthpieces, in order to achieve a repeated cleaning of the headlight glass covers. The compressed air used for cleaning, is received from the vehicle brake system and is initiated when the brake is activated. The signal for initiating the cleaning process is received from the vehicle brake light on brake activation, using the amount of air escaping into the atmosphere from the brake system. The vehicle brake cylinder (11) has a membrane (12) which, through the effect of compressed air, is pressed upwards and via a pressure bar (13) activates the wheel brakes by a lever arm (14). When the brake pedal (8) is released, a channel (15) is opened, allowing air to flow out into the atmosphere. |
