But i didn't realize it said doesn't fit xenon headlights and im not sure if i have them. I don't have headlight washers if that's a sure way to know. It's a 2005 c320 4matic.

Here are some pictures i hope there halogen.

most likely your car has regular standard halogen bulbs, not xenons. cant tell by looking at the picture., you need a pic of the back of the headlights bulb socket. behind the headlight cap.
