1. A lighting device comprising:
- an ultraviolet light source emanating ultraviolet light;
a visible light source coupled to the ultraviolet light source, the visible light source emanating visible light; and
a light directing device arranged to direct the visible light in a first direction primarily within an angle of illumination, the light directing device being further arranged to direct the ultraviolet light in an area wider than the angle of illumination, with the angle of illumination being centrally located within the wider area thereby causing the ultraviolet light to be symmetrically arranged relative to the area of illumination.

10. A vehicle having a light fixture coupled thereto, the light fixture comprising:
-
an ultraviolet light source emanating ultraviolet light; a visible light source coupled to the ultraviolet light source, the visible light source emanating visible light; and a light directing device arranged to direct the visual light in a first direction away from the vehicle primarily within an angle of illumination, the light directing device being further arranged to direct the ultraviolet light in an area wider than the angle of illumination, with the angle of illumination being centrally located within the wider area thereby causing the ultraviolet light to be symmetrically arranged relative to the area of illumination. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
