PROBLEM TO BE SOLVED: To sufficiently secure drive capability of LED while preventing instantaneous blinking in a lighting system of an instrument for a vehicle. SOLUTION: The lighting system is equipped with a first lighting circuit 500 dimming the lighting of LED 200 when a tail switch 400 is actuated to operate, a second lighting circuit 600 lighting the daytime of LED 200, a micro computer 100 outputting a control signal controlling the second lighting circuit 600, and a switching circuit 700 terminating an operation of the second lighting circuit 600 when the tail switch 400 is actuated to operate. The second lighting circuit 600 is constituted as the one sufficiently securing the drive capacity of LED with a first and a second transistor 601, 602. COPYRIGHT: (C)2004,JPO&NCIPI
