A garage door status indicating system is provided including a power source. Also included is a switch having a first orientation when the garage door is open and a second orientation when the garage door is closed. A first indication circuit includes a red diode adapted to illuminate intermittently upon the switch being in the first orientation thereof, thereby indicating that the garage door is open. Associated therewith is a second indication circuit including a green diode adapted to illuminate continuously upon the switch being in the second orientation thereof, thereby indicating that the garage door is closed.

[ We claim:] [1.] A garage door status indicating system comprising, in combination:an alternating current source;a step down transformer having an input connected to the alternating current source for affording a voltage at an output thereof which is less than that received at the input thereof;a rectifier having an input connected to the output of the transformer for rectifying current receiving from the transformer;a fuse connected between the transformer and the rectifier for precluding the flow of current to the rectifier upon the same surpassing a predetermined amount;a capacitor connected to an output of the rectifier in parallel therewith for converting current from the rectifier to a direct current;a double pole double throw switch connected to the capacitor and further situated on a garage door of a garage, the switch including a first pair of output terminals and a second pair of output terminals, wherein the switch has an unbiased orientation for connecting the capacitor to the first pair of output terminals for supplying direct current thereto when the garage door is open and a biased orientation for connecting the capacitor to the second pair of output terminals for supplying direct current thereto when the garage door is closed;a first indication circuit including an integrated circuit having a first NOR gate with a first input connected to a first one of the first pair of output terminals of the switch and a second input connected to a second one of the first pair of output terminals of the switch, a second NOR gate having a first input connected to an output of the first NOR gate and a second input connected to the second one of the first pair of output terminals of the switch, a first red diode connected between an output of the second NOR gate and the second one of the first pair of output terminals of the switch, wherein the red diode is adapted to illuminate intermittently upon the receipt of direct current by the first circuit thereby indicating that the garage door is open; anda second indication circuit including a resistor and a green diode connected in series between the second pair of output terminals of the switch for illuminating continuously upon the receipt of direct current by the second circuit thereby indicating that the garage door is closed;wherein the first and second indication circuits are situated on a panel which is mounted within a home associated with the garage.
