The inventive device includes a warning signal light powered by the vehicle power supply, and a control circuit including a switch actuated by an actuating linkage connected to an inlet valve of the carburetor and a flashing device, for controlling operation of the warning light. The flashing device periodically interrupts the current so that the warning light flashes.
