Headlights of car has reflector why?

Dear student Reflector headlights have featured as standard on vehicles since the invention of electric headlights. A reflector headlight consists of a bulb encased in a steel bowl. Mirrors are place within the bowl to reflect light out onto the road. They're cheaper to make. Manufacturers often use reflector headlights simply because they're less expensive. They're smaller. Projector headlights are deeper, taking up more space within the vehicle.  Regards
