BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a selective indoor light actuating device of a motor vehicle, and more particularly to an actuating device capable of selectively illuminating each seat for illuminating unidirectionally for illumination in a cabin.;That is, the main switch unit 100 mounted on one side of the driver's seat to selectively turn on / off the lights in the cabin, and the flip-flop unit 200 outputting a logical path as an input signal of the main switch unit 100. And a programmable array logic integrated circuit unit 300 for generating an output signal through logic operation as an input signal of the flip-flop unit 200, and a logic operation connected to an output terminal of the programmable array logic integrated circuit unit 300. A logic operation unit 400, an auxiliary switch unit 500 for outputting an on / off signal to the logic operation unit 400, and a relay unit 600 connected to an output terminal of the logic operation unit 400 to switch a signal. And an indoor light unit 700 connected to the output terminal of the relay unit 600 to turn on / off the lights, and the indoor light units 701-705 are mounted at the center of the vehicle interior and at the upper left of each seat. Real light can be obtained The lighting efficiency was improved, and the main switch 100 mounted on one side of the driver's seat was used to sequentially turn on / off the lights through the sequential dots / lights of the interior indoor lights 701-705 and the respective auxiliary switches 101-104. It is possible to increase the convenience and width of the convenience device of the car.
