1. A fuel saving signaling apparatus for a motor vehicle including an ignition system, a source of electrical energy, a motor and a rotatable means which is rotated when the vehicle is driven, comprising,a normally closed switch means operatively electrically connected to the ignition system and source of electrical energy,a signaling means,a first electrical time delay means series connected to said switch means and said signaling means and imposed therebetween,said first time delay means energizing said signaling means after a predetermined period of time has elapsed after said first time delay means has been energized by said switch means,said switch means being positioned adjacent said rotatable means and being operatively connected thereto so that said rotatable means will cause said switch means to move from its closed position to its open position when said vehicle is being driven thereby preventing the energization of said signaling means while said vehicle is being driven but permitting said switch means to move to its closed position when the movement of the vehicle has been halted thereby energizing said first time delay means so that the signaling means will be energized when the motor vehicle has been idling for a predetermined length of time.
