Anyone which bulbs are good quality to get for my S320 51reg as this a early model Mercedes dealers want £2000+ for new headlights units so i thought just buy the bulbs and put them in i know the quality isnit good to be good

 

Try here:

and use the bulb search on the right. Yours is the W220 if I remember rightly (I had one as my last car).

But there is a WORLD of difference between genuine HID (Xenon) units and so-called "Xenon bulbs"

And you can't just put an HID Xenon bulb into a standard headlight, it won't fit, and it won't work.
