Hey !!
Concave mirror is used in headlights of vehicles because when an object is kept at the focus of a concave mirror, the light rays after reflection from it travels parallel to each other. Therefore, the bulb of the headlight are kept at the focus of the concave mirror, thereby spreading out the light after reflection.
Good luck !!
