As it is known to all, the brightness of firebug can only be seen clearly at night, which is because its brightness is not the same as that of the twinkling color lamps. The brightness of the color lamps is monotonic but that of the firebug is changing from strong to weak and its short-lived and super bright. This circuit is designed based on the emitting principle of firebug. NE555, R1, W2, C1, C2 form the multivibrator while RG, W1 and VT form light activated circuit. Mimic bus is made up of LED1, LED2, VD1, VD2, C3 and C4.
