The 220V alternating current is rectified by bridge VD1-VD4, and one channel supplies power to the four colored lights Hl--H4. The other channel
supplies power to the integrated block A through resistor Rl step-down current limiting and capacitor C1 filtering. The four output terminals LI-L4 of the integrated block
VSl~VS4 to turn on and off in sequence, so that the colored lights H1~H4 light up in sequence, creating a sense of horse racing flow. Adjusting
the resistance of the potentiometer R_P can change the running speed of the four-way colored lights H1~H4.
