Abstract
A lighting fixture apparatus for a vehicle is disclosed wherein both left and right side lighting fixtures or lamps may not be extinguished simultaneously and maintain a necessary function even if a light source extinguishes due to malfunction of the light source or its control circuit. Two optical transmission devices are provided each of which has a light source, two optical cables connected to both sides of the light source, and flat and hot zone luminous intensity distribution lenses connected to both ends of the two optical cables. The flat and hot zone luminous intensity distribution lenses are distributed to both the head lamps. An illuminating range obtained by combining illuminating ranges wherein both the lenses mounted on one of the optical transmission devices illuminate is similar to an illuminating range obtained by combining illuminating ranges wherein both the lenses mounted on the other optical transmission device illuminate. Thus, even if one of the light sources extinguishes the illuminating range and simultaneous lighting of both the lighting fixtures may be maintained.
