Remember when Volvos had wipers on their headlights? Every wonder why? The short answer simply is "safety". The longer explanation is that Volvo realizes how important and difficult it is to keep your headlights clean. You might not notice it upon first glance, but it doesn't take much dirt, grime, snow or muck to significantly reduce your headlight's performance.
To this day Volvo includes headlight washers (though the wipers have since vanished) on all of their vehicles. A high pressure spray operates when you turn on your windshield fluid...because, if your windshield is dirty, chances are your headlights are dirty as well.
