Headlight washers

[Teshie]

Still haven't sorted the vibration issue I have with my car (w221 s320 2008) but I've discovered another anomaly......headlight washers don't work or the car hasn't got them
Do they come standard or is it an option?

If your car has xenon lights then you will have headlamp washers.
MOT failure if not working. (Cars with xenons only).
