Abstract: The invention concerns a head-light system for motor cars, comprising at least one or more, especially two housings (1) for head-lights and at least one light-emitting body in each housing (1), wherein the light emitting body is situated in a translucent outer vessel (4) made advantageously of glass if the housing (1) cannot be sealed hermetically and in an outer vessel (4) or without it if the housing (1) can be sealed hermetically, wherein at least one light-emitting body, and advantageously one in each housing (1) is made in form of a high-pressure gas discharge vessel (3) having a wall made of ceramics material. The main advantage of the proposed headlight system is that the visibility conditions during driving in darkness can be improved in comparison with the known solutions.
