Can I do a Hid kit on clear c43 head lights?????

You'd be better off using a high-quality bulb in those housings. If you are dead-set on using HID's, I would suggest getting either a factory set from a junked C-Class, or fabricating these eBay housings and use a true projector lense.
I lucked out since my car came with HID's. However, the technology was fairly new, so they are not in projector housings. But still, the light output is amazing compared to stock C-Class halogens.

Check your wiring and /or mounting points for your ballasts. I don't believe stock C-Class headlights use ballast modules.
