It is obvious to emphasize its importance in the matter of security and also they are today an essential part of the design of the cars. In fact, now that identity have been lost because the grills disappeared, and the plastic swallowed the surnames of the cars, the look of their lights is the only trait that identifies them. It is called downlight, recessed light descending to any lamp that illuminates directly and in a horizontal position downwards, the light it is projecting concentrated in a single point, thus preventing the light from expanding through the rest of the passenger compartment. The lamps are recessed and commonly are wrapped in a reflector to focus the light beam in a rather small area avoiding light scattering characteristic getting a very light. Although this type of lighting is similar to that used for headlights or lights, cannot be considered "downlights" because not used vertically, spotlights or lamps downlights itself fixed to the ceiling would be considered.
