Equipment on automotive vehicle (

20

) is controlled by a system at least one semiconductor light sensor (

170, 170

′) having variable sensitivity to light. Each light sensor generates a light signal (

164

) indicative of the intensity of light incident on the light sensor. Control logic (

66

) varies the sensitivity of the light sensor and generates equipment control signals (

166

) based on received light signals. Sensitivity of light sensors (

170, 170

′) may be varied by changing the integration time (

228

) for producing charge from light (

176

) incident on light transducers (

178

), by selecting between light transducers (

178, 490, 500, 504

) of different sensitivity within the light sensor (

170

), by using a light transducer (

530

) with a sensitivity that is a function of the amount of incident light (

176

), and the like. Controlled equipment includes devices such as automatically dimming rearview mirrors (

24,26

), headlamps (

44

), and moisture removal means (

38, 40, 42

).
