1. A system for automatically controlling equipment in an automotive vehicle, each piece of vehicle equipment controlled by an equipment control signal, the system comprising:

  • at least one semiconductor light sensor, each semiconductor light sensor operative to output a discrete light signal based on light incident over a variable integration period; and

    a control logic in communication with the vehicle equipment and the at least one semiconductor light sensor, the control logic operative to generate at least one equipment control signal based on the discrete light signal, wherein the at least one light sensor comprises;

    a light transducer exposed to light, the light transducer operative to accumulate charge in proportion to light incident over the integration period; and

    a sensor logic in communication with the exposed light transducer, the sensor logic operative output the discrete light signal according to the accumulated exposed light transducer charge.
