Hello. How I can pull out this metallic ball end from the car? Thanks

Undo the bolts and give it a good yank usually does the trick.

I have a pair of Marea lights if you fancy them.

Hello, thanks for your answer, it seems i can't pull it out i tried with all my strength i'm afraid i might break it..

I just bang the headlight with my hand on the indicator until it pops off.
The impact usually pops it off easier than just pulling it.

A few mm space for impact but after a few tries i heard a sharp snap sound, and the unit was removed. Thank you both..
