Abstract: An automobile annual inspection reminder device sets off flashingly a bright light emitting diode (LED) approximately a month before the due date of the next automobile inspection. The device employs conventional battery operated digital watch circuitry to facilitate the setting of a counter/memory to the current time and date and the storage in memory of representations of the inspection due month and day thereof as well as of an earlier alarm date differing by a predetermined interval from the inspection-due date indicated by the facility and storing the same in the memory. A micro switch is provided for each of the twelve months of the year to set the inspection due date in memory. A "Snooze" button provides for temporary inactivation of the LED or beeper. After an inspection, the device can be set to the new inspection-due date.

Abstract: A rectangular vehicle license plate frame includes side columns which mount printed circuit boards internally. The printed circuit boards mount yellow dot transformers and an integrated chip and light a number of light emitting diodes mounted on the external surface of the columns proportionate to the strength of the signals received. The strength of the signals received is dependent on the output of the respective channels of the vehicle's stereo system to which the printed circuit boards are connected by appropriate wires. Connections to the vehicle's battery provide power for energizing the respective diodes. Thus the license plate frame displays an unlimited variation of patterns in which various numbers of LEDs are illuminated in accordance with the strength of the outputs of the stereo system in rhythmic-like fashion.
