Nowadays, cars have become an indispensable means of transportation in people's lives, and their safety issues have also received great attention from the society. Among all the components of a car, the importance of taillights to car safety is self-evident, and its existence has greatly reduced the occurrence of traffic accidents. Therefore, how to design the various functions of taillights to maximize their value is an urgent problem that major manufacturers need to solve. With the development of technology, today's car taillights not only have a varied appearance, but also have greatly improved their functions, and this is mainly due to the design of the taillight control circuit. The low-cost automotive lighting general-purpose microcontroller solution launched by WPG based on Infineon has ultra-high scalability and can achieve flexible taillight control design.
