Thanks to Rabmurray, here's a guide on removing the front bumper and removing the headlights. To remove the headlights, you have to drop the bumper first.

Thanks, for your guidance.

I've got a question regarding the headlights, mine are adaptive xenon (turning included). I've noticed that they have small cracks on the top, and some water dripped inside and made foggy trails down the end of the headlamps ... how complicated is it (or isn't it) to disassemble the xenon headlamp? My idea was to remove the xenon lamp cluster, which would present a huge hole from the back side, and I'd manage to clear the headlamp glass from the inside ... I wouldn't want to remove the glass from the plastic housing and then gluing/heating it back up.
