A vehicle built-in electric jack system, including a plurality of electric jacks capable of lifting a vehicle. The plurality of jacks operates using a 12-volt power supply. The plurality of jacks are telescopic jacks. Each jack is made from a plurality of cylinders. The cylinders are apportioned such that each cylinder for a jack fits inside of the previous cylinder. Each of the plurality of jacks has a minimum of one light placed on the jack. The light is directed toward the wheel well of the vehicle. The jacks and lights are attached to a controller. The controller is located inside of the vehicle such that the jacks and lights can be operated while the user is inside of the vehicle cab. Further, each jack has a rocker switch located thereon that can control the jack to which it is attached.

A control apparatus for driving a laser diode comprises an output connection for connecting the laser diode, a regulation device for generating an output signal, a detector device which is designed to determine a regulation variable when the regulation device provides the output signal and the laser diode is connected to the output connection. The control apparatus furthermore comprises a computer device for providing a control signal for the regulation device, wherein the computer device provides the control signal independently of the regulation variable. The regulation device is designed in such a way that it generates a level for the output signal depending on the control signal and the determined regulation variable.
