Abstract
A vehicle light assembly is provided that includes a light source, a lens in front of the light source, conductive circuitry provided on the lens and forming a capacitive sensor for sensing moisture on the lens and a heater for removing the moisture, and switching circuitry for selectively energizing one of the capacitive sensor and the heater.
Claims20
A vehicle light assembly comprising:
- a light source;
- a lens in front of the light source;
- conductive circuitry provided on the lens and forming a capacitive sensor for sensing moisture on the lens and a heater for removing the moisture;
- and
- a controller selectively controlling energization of one of the capacitive sensor and the heater.

(canceled)
A vehicle light assembly comprising:
- a light source;
- a lens in front of the light source;
- conductive circuitry provided on the lens and forming a capacitive sensor for sensing moisture on the lens and a heater for removing the moisture, wherein the conductive circuitry has at least one electrode that generates a capacitive signal in a sensing operation and generates heat in a heater operation;
- switching circuitry for selectively energizing one of the capacitive sensor and the heater;
- and
- a controller controlling the switching circuitry.
