An electrical anti-theft device for a motor vehicle issues an audible alarm signal for a predetermined period of time in response to tampering with the vehicle which is sensed by the anti-theft device. At the end of the predetermined period of time, a strobe light is activated and operates continuously thereafter to indicate that the vehicle has been tampered with. At the same time, the electrical anti-theft device is reset so as to issue the alarm signal in response to further tampering with the vehicle. The electrical anti-theft device is incorporated in a mechanical anti-theft device mountable on a vehicle steering wheel to limit rotation thereof.

In an automotive vehicle comprising a dashboard and a windshield, the improvement comprising: a housing having a top surface, the housing being connected to the dashboard or the windshield; and a left rod, a center rod and a right rod extending from the top surface of the housing, the rods being parallel; wherein when the right rod overlaps a lane marker of a road, the vehicle is too close to the lane marker, when the left rod overlaps the lane marker of the road, the vehicle is too far away from the lane marker, and when the center rod overlaps the lane marker of the road, the vehicle is in the proper position, thereby allowing the driving assistance device to properly align the vehicle on the road. 11. The improvement of claim 10, wherein: the rods each include a light source located at an end thereof; and the housing and the rods include electrical wiring for connecting the light sources to a power source for illuminating the light sources; wherein the rods can be used at daytime by aligning the rods with the lane marker of the road and at nighttime by illuminating the light sources and aligning light from the light sources with the lane marker of the road. 12. The improvement of claim 11, further including: caps pivotally connected to the ends of each the rods; each of the caps including an aperture for allowing light from the light sources to exit the cap. 13. The improvement of claim 12, further including: a power cord connectable to the housing, the power cord having a male plug adapter adapted to fit within a cigarette lighter in the vehicle; the power cord being connected to the wiring for supplying power from the cigarette lighter to the light sources to illuminate the light sources. 14. The improvement of claim 12, further including: batteries located within the housing and connected to the wiring, the batteries supplying power to the light sources for illuminating the light sources. 15. The improvement of claim 10, wherein: the housing includes a first fastener; and the vehicle includes a second fastener on the dashboard or the windshield of the vehicle for mating with the first fastener for removably connecting the housing to the dashboard or the windshield. 16. The improvement of claim 10, wherein: the housing includes suction cups for removably connecting the housing to the dashboard or the windshield. 17. The improvement of claim 10, wherein: the center rod extends farther from the top surface of the housing than the left rod and the right rod. 18. The improvement of claim 10, wherein: each of the rods has an annular cross section. 19. The improvement of claim 18, wherein: each of the rods has a diameter of approximately 0.5 inches, thereby allowing the rods to be aligned with the lane marker without extending beyond the width of the lane marker. 20. A method of properly aligning a vehicle including a dashboard and a windshield on a road having a lane marker dividing the road into lanes, the method comprising: providing a driving assistance device including a housing having a top surface and a bottom surface, the housing further including a first side rod, a center rod and a second side rod extending from the top surface of the housing, the rods being parallel; placing a side of the vehicle directly adjacent any straight line; aligning the first side rod of the driving assistance device with the straight line; and connecting the bottom surface of the housing to the dashboard or the windshield of the vehicle; wherein when the first side rod or the second side rod is aligned with the lane marker of the road, the vehicle is too close to or too far away from the lane marker, and when the center rod overlaps the lane marker of the road, the vehicle is in a safe position spaced from the lane marker. 21. The method of properly aligning a vehicle of claim 20, further including: providing an end of each of the rods with a
