An electrically-adjustable light transmitter changes its light transmissivity responsive to an electric signal. By applying the electrically-adjustable light transmitter to a window and thereafter changing the electric signal to it, a window can be tinted and un-tinted. Jurisdictions that prohibit tinted vehicle windows are listed in a data base. A current location determined by a GPS is compared to data base entries. If the location is within an area where tinted windows are prohibited, a controller automatically un-tints the windows, or reduces the window tint to comply with applicable local laws. |
