Although the car did come with those, they're really worthless devices if you think about it. Non of my cars have ever had that feature yet I can still see fine at night w/o them. Most people wash their cars periodically or wipe obvious dirt off the headlamps if it becomes an issue, usually in winter.
The ONLY time I ever need to clean my headlamps only is in winter when heavy salt can worsen the headlamps efficiency, otherwise you'll never really them.
