Yes you do need them either that you'll have a big gapping hole for condensation.
If you are referring to the HID cover located in the back for the lowbeams, that needs to be removed when you change out the bulb, no they can not be bought separtely. I actually lucked out and found a set locally. I can see what I have in my "parts box" and let you know if I have one. What side do you need? drivers (L) or Passengers (R). BTW...What year is your coupe? Let me know
