1. An alarm system for reminding the driver of a commercial truck to fill out a log book, which comprising:

  • electronic components comprising integrated circuits, resistors, diodes, switches and a sound emitting device connected to an electrical circuit board;

    a power supply means for supplying 12 volts D.C. to said electrical circuit board;

    a housing means for housing said circuit board, said diodes and said switches;

    a magnetic material means connecting around a parking brake knob;

    a magnetic switch means connecting around the base of said knob, when said parking brake knob is pulled out, said magnetic material means leaves the close proximity of said magnetic switch means such that said magnetic switch means moves from closed to open position and causes said electrical circuit board to activate said diodes to light and said sound emitting device to emit a tone for alerting said driver to fill out said log book, and deactivating means for deactivating said alarm system by said driver activating a reset button of said deactivating means;

    wherein said magnetic material means comes in close proximity to said magnetic switch means causing said magnetic switch means to close when said parking brake knob is pushed in, causing said electrical circuit board to activate said diodes to light and said sound emitting device to emit a tone for alerting said driver to fill out the log book, and deactivating the alarm system by activating said reset button of said deactivating means;

    wherein one of said switches comprising a timer switch means, wherein said timer switch means is caused to activate a two hour timer such that said electrical circuit board, said diodes and said sound emitting device are activated every two hour period, and deactivating said timer switch means by activating said reset button of said deactivating means;

    electrical wires connecting said magnetic switch means to said electric circuit board;

    whereby pushing on said reset button causes said electrical circuit board to deactivate causing said diodes to stop lighting and said sound emitting device to stop emitting a tone.
