Need help with installing hid bulbs monogram
 

hey guys, i have an oem stock hid monogram/gt86 headlight. i was wondering how do i change out the hid bulbs. i opened the circle cover that incases the hid harness/projector but i dont know how to unlock it. i tried turning it the opposite direction of the marked down lock, but it wouldnt really turn much. do i need to unscrew the part?

if anyone has done this can you please help me out?

if you look at the 10th picture you can see the circle cover i am talking about

Push in and turn it counter clock wise. Should pop right out.
