Abstract

An automotive vehicle system includes a light and a module. The light is adapted to be attached to an exterior of a vehicle. The module selectively illuminates the light during a vehicle stationary period based on an electric drive system state of charge. The module further selectively illuminates the light during a vehicle driven period based on vehicle operating conditions different than the electric drive system state of charge.
