How does a reflector optics headlight work in a car?
The reflector optics headlight also has the filament in the light bulb at the base of the light, but uses multiple mirrors to achieve the light being spread properly. In these headlights, the lens is merely used as a protective cover for the light bulb and mirrors.

HID headlights work by running an electrical charge through xenon gas, which when excited gives off a bright, strong light. This light is much more efficient than halogen light, which is created when a filament is heated.
