A level regulator for an automotive vehicle such that a supply voltage is applied to the amplifiers only while the sensors are detecting level-regulating signals, so that a wasteful current can be prevented from being passed therethrough when the vehicle is left parked with one of the wheels on the sidewalk or an uneven ground, and the battery can be protected against excessive discharge. The level regulator of the present invention comprises mechanical switches such as microswitches or reed switches as the sensors, in place of electric, photoelectric or magnetic sensors used with conventional level regulators.
