looking for 300 C headlight parts

My neighbor has a 300 C and needs at least new hid bulbs. One is out. I told him I'd help him swap the bad one to the other side to make sure the bulb is bad, is there a better way to check? can you change the bulb without pulling the front facia? I might pull it anyways as his housing is all hazed on the inside and he wants to try to wash it out. does anyone have a drivers side headlight they want to sell kind of cheap? Or a set of good D1s bulbs? Also his mirror is broke. It's an auto dimming one and looks like there is coffee under the glass. I looked around and found it's a common problem, but new ones are really expensive. If anyone has a drivers side mirror, auto dimming or not let me know.

I have some spare stock D1S Phillips bulbs from when I changed mine to 6000K And you don't need to take off the facia. Tell him to try looking for D1S bulbs online. They are cheap....ish.

what is the oem temp 5k? Do you want to sell your old ones?

4300K is stock. I had some as spares if he would like to test but I don't wanna sell them at this time just in case

cool. I'll tell him to get the philips for about 160 a pair. I have a spare 6000k I'm going to use to test everything.
