A system for automatically controlling actuation of various parts of an automobile in accordance with various sensed conditions. Four photocells are mounted, preferably about the periphery of the courtesy light inside the automobile on the roof, to receive ambient light from four orthagonal directions and are connected to a logic circuit to produce a signal causing the automobile's lamps to be turned off only when all four of the photocells are sensing daytime conditions and to be turned on, after a short delay, when any of the photocells senses nighttime conditions which persist during the delay. A water cell is mounted at the base of the windshield so that during a rain shower the water cell will become conductive. The water cell is also connected to the logic circuit and to a motor driver circuit, which signal produced by the conductive water cell causing the lights and windshield wipes to be actuated as long as the shower continues.
