Hi, new to the forum. Just picked up a 98' e320

I'm looking to replace the headlights with some updated looking projectors.
Now, I'm not sure if my year e320 comes stock with hid's or not.
But I've removed my headlights, and they are definitaly hid's. Maybe they were upgraded by the previous owner....

Now my question is.

If I order these http://cgi.ebay.com/ebaymotors/96-98...75843456QQrdZ1

Am I going to be able to take my hid ballasts, and bulbs and mount them directly to these headlights?
And has anyone had any expeirience with ebay headlights? Quality, fitment, water seal ect....?

Any help would be much appreciated.

Scott
