Abstract
A light system for a vehicle is provided herein. The light system includes first and second light sources. A lens is configured to create a first illumination pattern when the first light source is activated and a second illumination pattern when the second light source is activated. A third light source is configured to create a third illumination pattern that extends vehicle outward of the first and second illumination patterns. A controller is configured to activate the first light source when a front door of the vehicle is opened and activate the second light source when a rear door of the vehicle is opened.
Claims18
A light system for a vehicle, comprising:
- first and second light sources on a doorsill;
- a lens configured to create a first illumination pattern when the first light source is activated and a second illumination pattern when the second light source is activated;
- a third light source configured to create a third illumination pattern that extends vehicle outward of the first and second illumination patterns;
- a controller configured to activate the first light source when a front door of the vehicle is opened and activate the second light source when a rear door of the vehicle is opened;
- and
- a light sensor configured to detect a presence of a compound on an outer surface of the lens.
A vehicle light system, comprising:
- a light source disposed on a doorsill of a vehicle;
- a lens operably coupled with the light source and configured to direct light towards a ground surface proximate an exterior portion of the vehicle;
- and
- a light sensor configured to detect a presence of a compound on an outer surface of said light system by detecting an amount of incident light reflected by the outer surface of the lens.
A light system, comprising:
- a substrate and a lens, the substrate coupled to a doorsill of a vehicle;
- a first light source configured to illuminate a portion of ground proximate a front door;
- a second light source configured to illuminate a portion of ground proximate a rear door;
- a third light source configured to illuminate a ground surface outwardly of the first and second light sources;
- and
- a light sensor configured to detect a presence of a compound on an outer surface of the lens.
