Automotive taillight control circuit design

(Assume there are 3 indicator lights on each side of the rear of the car. All lights are off when the car is running normally. When turning right, the 3 lights on the right side will light up in a right-circuit sequence. When turning left, the 3 lights on the left side will light up in a
left-circuit sequence. When braking, all lights will flash simultaneously.) (1) Design, simulation and debugging of
the right-circuit circuit of the headlights; (2) Design, simulation and debugging of the left-circuit circuit of the headlights;
(3) Design, simulation and debugging of the delay circuit. When the headlights are cyclically lit and flashing, the lighting and extinguishing time is 2 seconds, with an accuracy greater than 10%;
(4) Design, simulation and debugging of the state switching circuit; (
5) Scheme design and demonstration;
(6) Use relevant software to design and simulate the circuit diagram, and analyze and summarize the simulation results.
