Abstract
A cover for use in connection with one or more vehicle lights is provided. A lens of the cover contains an electrically activatable material that prevents the transmission of visible light from entering into and reflecting out from one or more of the vehicle lights when the electrically activatable material is set to a light inhibiting state. The cover may be configured to be releasably installed over one or more of the vehicle lights such as military combat vehicle lights. A coupling device electrically couples the electrically activatable material to an electrical power source. An actuator is adapted to set the electrically activatable material of the lens to the light inhibiting state in response to user operation such that the lens prevents the transmission of visible light from entering into and reflecting out from the one or more vehicle lights to reduce the observability of the one or more vehicle lights.
