     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 1-8 thereof, a new lawnmower headlight system embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described. 
     More specifically, it will be noted that the lawnmower headlight system 10 comprises a generator means 12 (see FIG. 8) mechanically coupled to or forming a portion of an engine 14 of a lawnmower 16 for generating electrical power in response to an operation of the engine. An illumination means 18 is mountable to the engine 14 of the lawnmower 16 and is electrically coupled to the generator means 12 for providing illumination directed forwardly of the lawnmower 12. A control switch 20 is positioned in electrical communication with the illumination means 18 and is mounted to a handle 22 of the lawnmower 16 for controlling both an energization of the illumination means 18 and a dimming control thereof, as shown in FIG. 1 of the drawings. 
     Referring now to FIG. 8, it can be shown that the generator means 12 of the present invention 10 preferably comprises an upper housing member 24 and a lower housing member 26. An unillustrated output shaft of the engine 14 projects through apertures in the housing members to couple with a flywheel 28 so as to rotatably mount the flywheel above the upper housing member 24. The flywheel 28 may include unlabeled fins, as shown in FIG. 8, projecting therefrom which operate to cause a flow of cooling air over the engine. A rotor 30 is mounted to the engine shaft of the engine and rotates within and between the housing members 24 and 26. A stator 32 is mounted within the housing members 24 and 26 and positioned within or adjacent to the rotor. The stator 32 is electrically coupled to a power cable 40 extending from the generator means and is separated from the interior surface of the lower housing 26 by an insulator 34 interposed therebetween. The rotor 30 includes permanent magnets or the like such that a rotation of the rotor by the engine shaft attached thereto will generate an induced current in the stator 32, thereby generating power for use by the illumination means 18. By this structure, rotational torque from the engine shaft of the engine 14 is converted into electrical power dispensed through a plurality of conductors in the power cable 40 extending into electrical communication with the control switch 20. 
     As best illustrated in FIG. 7, it can be shown that the control switch 20 of the present invention 10 preferably comprises a switch housing 42 having a power switch 44 and a dimmer switch 46 mounted relative thereto. The switch housing 42 is shaped so as to define a handle bore 48 directed therethrough which receives a portion of the handle 22 of the lawnmower 16 so as to mount the control switch 20 in a readily accessible position as shown in FIG. 1 of the drawings. The power switch 44 and the dimmer switch 46 are electrically coupled to the power cable 40 and to a control cable 50, with the control cable extending into electrical communication with the illumination means 18. By this structure, selective operation and control of the illumination means 18 can be remotely effected by an individual pushing the lawnmower 16 from behind the handle 22 as shown in FIG. 1 of the drawings. 
     Referring now to FIGS. 4 through 6, it can be shown that the illumination means 18 of the present invention 10 preferably comprises a light housing 52 mounted to the engine 14 of the lawnmower 16. The control cable 50 extends through the light housing 52 from the control switch 20 and is electrically coupled to a dual-beam headlight 54 mounted within the light housing 52 and behind a front lens 56. The dual-beam headlight 54 is of a conventionally known automobile-type which includes both high and low beams. Thus, the dimmer switch 46 operates to control a distribution of electrical power to the dual-beam headlight 54 so as to effect selective operation of either a high or low beam thereof. 
     In use, the lawnmower headlight system 10 of the present invention can be easily incorporated into a lawnmower 16 as shown in FIG. 1 of the drawings. The illumination means 18, when energized by the generator means 12 through manual controlling of the control switch 20, illuminates an area in front of the lawnmower 16 to allow an individual to mow a lawn during poor ambient light conditions such as during nighttime or the like. 
     As to a further discussion of the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided. 
     With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. 
     Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
