In addition, when the indoor light operation button 2a is operated once more and the operation signal is applied to the control unit 4 while the left second indoor light 12 is turned on, the control unit 4 controls the left second light. The control signal to the indoor light driving unit 10 is blocked and a predetermined control driving signal is output to the right first indoor light driving unit 14 so that the right first indoor light 16 is turned on.

Then, the right first indoor light driving unit 14 drives the right first indoor light 14 to light up by driving control of the controller 4 so that the right first indoor light 16 lights up.

In addition, when the indoor light operation button 2a is operated once more and the operation signal is applied to the control unit 4 while the right first indoor light 16 is turned on, the control unit 4 controls the right first light. The control signal to the indoor light driving unit 14 is interrupted and a predetermined control driving signal is output to the right second indoor light driving unit 18 so that the right second indoor light 20 is turned on.

Then, the right second indoor light driving unit 18 drives the right second indoor light 20 to be turned on by driving control of the controller 4 so that the right second indoor light 20 is turned on.

When the indoor light operation button 2a is operated once more and the operation signal is applied to the control unit 4 while the right second indoor light 20 is turned on, the control unit 4 controls the right second light. It outputs a predetermined control drive signal to the central indoor light driver 22 so that the operation signal to the indoor light driver 18 is blocked and the central indoor light 24 is turned on.

Then, the central indoor light driver 22 drives the central indoor light 22 to be turned on by the drive control of the controller 4.

In addition, when the indoor light operation button 2a is operated once more and the operation signal is applied to the controller 4 while the central indoor light 22 is turned on, the controller 4 controls the central indoor light driver 24. In order to block the operation signal to the and the rear first indoor light 28 is turned on, a predetermined control drive signal is output to the rear first indoor light driving part 26.

Then, the rear first indoor light driver 26 drives the rear indoor light 28 to be turned on by the drive control of the controller 4.

In addition, when the indoor light operation button 2a is operated once more and the operation signal is applied to the control unit 4 while the rear first indoor light 28 is turned on, the control unit 4 controls the rear first operation light. It outputs a predetermined control drive signal to the rear second indoor light driver 30 so that the operation signal to the indoor light driver 26 is blocked and the rear second indoor light 32 is turned on.

Then, the rear second indoor light driver 30 drives the rear second indoor light 32 to be turned on by the drive control of the controller 4.

According to the present invention made as described above, according to the operation of the indoor light operation button installed on the driver's seat side, the indoor light installed at a predetermined position of the vehicle is sequentially lit, the user can easily operate the indoor light lighting.
