PURPOSE: An indicator lamp system decreases the energy waste of an indicator lamp by making the light of each switch on only when the hand of a driver is at a certain distance from the switch. CONSTITUTION: An indicator lamp system comprises a data detector device(10), a control device(20) and a timer device(30). The data detector device(10) detects each data of a driving car and outputs a signal. The control device(20) analyzes the signal of the data detector device(10) and outputs a control signal to light up an indicator lamp. The timer device(30) actuated by the control signal of the control device(20) lights up the indicator lamp by outputting an electric signal only during the time set up. Therefore, the indicator lamp system provides the convenience of a driving, and decreases the waste of an energy.
