Hey ghettobird, just wanted address your concerns about your HID setup as I have gone down this route before.
Initially I started out with a Phillips Ultinion 6000k HID bulbs with ballasts for my c230k. I kept the standard halogen headlamp assemblies and lenses. This is what they looked like:
They were very bright, but also threw off some crazy glare and did not light the road up very well. There were round hotspots on the road and the beam pattern was messed up and did not light up the periphery of the car very well. That's why after a few months of them I replaced them with a pair of high quality standard halogen bulbs again. Although the halogens were more yellow, I could see more of the road which was more important to me. I waited and found a set of oem Mercedes Benz w202 xenon assemblies from a wrecked C43 and then "retrofitted" them on to my car. And no, they are not projectors.
The original equipment Xenon assemblies specific for our W202 has a different headlamp lenses to give a correct beam pattern. Also, inside the assembly is a big piece of gray metal that acts as the glare shield. The internals of the Oem xenon headlamp assembly is very different from that of the halogen assembly.
This is what the proper xenon headlamps should look like. No glare and lights the road perfectly.
The lenses are bit darker because of the metal glare shield inside of the headlamp.
I hope this helps. Finding the oem xenon assemblies nowadays is virtually impossible and if you do find them, they are extremely expensive. The aftermarket DDM hid kit you got shouldn't be that bad, if you don't want to blind oncoming traffic, I guess you could just aim your lights down a little bit. It's a tricky process to get the aftermarket HIDs to look perfect. On one hand, you don't want to blind oncoming traffic, but if you aim too low, the lights won't project as far down the road.
Let me know if you have anymore questions
