Vehicle front lighting assembly and systems having a variable tint electrowetting element
Abstract:
A vehicle front lighting assembly, or headlight assembly, that includes one or more variable tint electrowetting elements overlying a portion of the assembly lens surface. The variable tint electrowetting element is configured to operate to a transparent state whereby the hue of light passing therethrough is not changed, and a tinted state where the hue of light passing therethrough is changed. Alternatively, the variable tint electrowetting element is configured to operate to the tinted state and an opaque state where light is blocked from passing through the electrowetting element. The assembly may use light emitting diodes (LED) as an alternative to more conventional light sources.
