An automatic illumination circuit (36) coupled to an ignition switch (14) of an automotive vehicle and to at least one light switch (24) therein. The circuit (36) continuously energizes at least one light (22) when a source of electrical energy (10) such as an alternator supplies electrical energy to the circuit (36) and the ignition switch (14) is in a first operating state for rendering the engine of the vehicle operable. At least one light (22) is automatically illuminated whenever the engine is running, regardless of the time of day or night, regardless of whether the vehicle is in motion, and regardless of whether the operator remembers to activate the light switch (24).
