Headlight bulb in FF?

It's BiXenon - so there is no "headlight bulb" to replace - you might need to replace the complete package:

May I ask why you are asking? Is it to try to "improve" the very bad headlights (I consider them close to useless - yes I get some kind of lights out of them, but it not even close to a normal car's output)?

 

If it’s bi-xenon (and not LED) then the bulbs should be replaceable. Check along the bottom of the headlight lens, as the type of bulb the housing uses will typically be etched. Brighter Xenon bulbs are available. Check out XenonDepot or theretrofitsource for replacement bulbs or guidance.
