A switchable vehicle lamp lens assembly , comprising: a vehicle lamp assembly, comprising: a lens having a first transparent layer and a second transparent layer adjacent the first transparent layer; a switchable electrochemical film disposed within the lens between the first transparent layer and the second transparent layer; and one or more light sources positioned behind the lens ; in an active mode, the switchable electrochemical film is adapted to be substantially transparent when a voltage is provided thereby enabling light transmission through the lens from the one or more light sources ; in a non-active mode, the switchable electrochemical film is adapted to be substantially opaque when the voltage is removed thereby blocking light from the one or more light sources; a controller configured for controlling when the switchable electrochemical film is alternately switched between the active mode and the non-active mode such that the vehicle lamp assembly is configured to provide an automotive lighting function; wherein the switchable electrochemical film comprises a plurality of segments arranged in different portions of the lens, each of the plurality of segments being independently controllable via the controller by alternately switching one or more segments between the active mode and the non-active mode thereby switching the corresponding lens segment between a substantially transparent state and a substantially opaque state, respectively to provide a multi-function lens; and characterised in that each of the plurality of segments is activated to become substantially transparent in a predetermined sequence, such that the different portions of the lens are configured for illumination by the one or more light sources in an active pattern that appears to move across the vehicle lamp assembly for providing a dynamic turn signal. a vehicle lamp assembly, comprising: a lens having a first transparent layer and a second transparent layer adjacent the first transparent layer; a switchable electrochemical film disposed within the lens between the first transparent layer and the second transparent layer; and one or more light sources positioned behind the lens ; a lens having a first transparent layer and a second transparent layer adjacent the first transparent layer; a switchable electrochemical film disposed within the lens between the first transparent layer and the second transparent layer; and one or more light sources positioned behind the lens ; in an active mode, the switchable electrochemical film is adapted to be substantially transparent when a voltage is provided thereby enabling light transmission through the lens from the one or more light sources ; in a non-active mode, the switchable electrochemical film is adapted to be substantially opaque when the voltage is removed thereby blocking light from the one or more light sources; a controller configured for controlling when the switchable electrochemical film is alternately switched between the active mode and the non-active mode such that the vehicle lamp assembly is configured to provide an automotive lighting function; wherein the switchable electrochemical film comprises a plurality of segments arranged in different portions of the lens, each of the plurality of segments being independently controllable via the controller by alternately switching one or more segments between the active mode and the non-active mode thereby switching the corresponding lens segment between a substantially transparent state and a substantially opaque state, respectively to provide a multi-function lens; and characterised in that each of the plurality of segments is activated to become substantially transparent in a predetermined sequence, such that the different portions of the lens are configured for illumination by the one or more light sources in an active pattern that appears to move across the vehicle lamp assembly for providing a dynamic turn signal. <EOS>
