Thanks! I did it according to your video. But one thing that needs to be mentioned here is, when you take off the bulb holders of both sides, rotate them in the same way: i.e. both counterclockwise.
keep the top part of the clip out of the bottom part, use a screwdriver to tap the bottom part as you align it with the hole, it will straighten out and slide in just use your thumb to push the rest of clip in.
