PURPOSE:To enable illumination of a curve running direction during the night and to enable safety driving of a car, by a method wherein, by means of an electric signal transmitted by a transmitting key, attached to the base of a handle, during rotary passage, a curve running illumination light on the necessary side is automatically continuously lighted until curve running is completed. CONSTITUTION:When a handle is turned to the left and in a 200 deg. arc after exceeding 160 deg. arc, a transmitting key, attached to the base thereof, passes in a condition to depress a buttom P of a micro switch 7, and thereby a signal is transmitted to a timer block 33 and a power block 11. A signal from the block 33 is inputted to a terminal 35, and with the electromagnetic coil of a relay R9 by means of a current flowing from an output terminal, a current flows from the R9 to a block 12. By means of the signal, a current flows from a terminal 18 with the aid of a flip flop C-MOS circuit of the block 11, the electromagnetic coil of a relay R3 is excited, and the current continues to return to a terminal 25. This excites the coil of a relay R1, and causes a current to flow to a new forming circuit to light a left curve running light 10 for illumination. As noted above, 3 switches are pressed during in turn through rotation, and light off lights in turn by return. |
