Abstract
A cover for use in connection with a vehicle light having a light source and a light reflector is provided. A lens of the cover has an electrically activatable material switchable between a light inhibiting state and a light transmissive state. The electrically activatable material prevents the transmission of visible light from entering into and reflecting out from the vehicle light when the electrically activatable material is set to the light inhibiting state. The lens has an area without having the electrically activatable material such that visible light from the light source is also to pass through the area. A baffle having the electrically activatable material extends from the body of the lens. The baffle blocks a portion of the visible light that passes through the area of the lens from traveling in certain directions when the electrically activatable material is in the light inhibiting state.
