Hello, in order to change the bulbs you're going to need to remove the headlamp housings from the vehicle, here's the procedure to do that.
Using a socket with a magnetic insert or with a small piece of butyl tape inserted, reach down between the grille and the FEM carrier to access, remove and retrieve the screw (3) that secures the lower mounting tab of the front lamp unit.
NOTE: The illustration shows the back of right front lamp unit and slide lock with the slide lock in the locked position.
Once you have the housing out you can swap over the bulbs and reinstall.
