I heard that when the light gets dirty it distorts the light and affects drivers coming towards you. I have auto level and wash on my cooper s, light spread is great and washers are cool. I've installed HID's before at work and no one has been concerned about not being legal!
Yep, that's the reason for washer jets. The light defracts a lot when the lens is dirty and glares oncoming drivers.
Also, you need projector type headlights which provide a sharp cutoff to prevent glare too. Not cheap to do it right.
