Yes, the bulb will be kept at the focus of the parabola so that the light after refelction would go parallel and so it could cover a wide region.
Convex usually, its used as a light source and not as a magnifier (or imager of any sort).
A concave mirror is used in headlights and searchlights as it can reflect and focus light beams to a single point, creating a strong and concentrated beam that can travel long distances. The mirror's shape allows it to gather light from a wide area and direct it in a specific direction, increasing the reach and intensity of the light projection.
The light rays come together to make a bright spot of light. When a concave mirror is used in car headlights, a bulb is placed at the spot where light would come together. This has the effect of making the opposite happen. The rays of light shining out from the bulb are reflected off the concave mirror to make a strong beam of light, which travels out in front of the car to shine on the road.
Car headlamps use parabolic mirrors to concentrate and focus the light in one direction. Without these mirrors, one would either waste the undirected light or the light would shine in all directions, which would blind the driver.
No, the size of your head does not actually change when you stand in front of a mirror. As mirrors reflect back what is in front of them, your head will appear the same size regardless of your proximity to the mirror. The perception of size may change based on distance and angles, but your actual head size remains constant.
Concave mirrors are used because they will reflect a light source inside the curve in one general direction. To be more specific, the mirrors are close to parabolic. Parabolas have the property that light beams generated at the focal point of the parabola are all reflected parallel out of the mirror.

Car headlights use concave mirrors to focus and direct light beams in a specific direction. The shape of the concave mirror helps to gather and reflect more light outward, increasing the brightness and distance of the light beam. This design improves visibility for the driver and helps illuminate the road ahead.
Head height.
what light?! head light, tail light, parking light, rear view mirror light, rear hatch light, underhood light, etc.
Check the back of your rear view mirror.
