Abstract:

With the ever increasing traffic accidents,the safety and reliability of the car taillight control circuits become more and more important.This paper proposes a car taillights analog control circuit by the basic methods of digital logic design with 6 LEDs,9 integrated circuit chips,2 capacitors,and some resistors.Experiments show that the system can achieve the 4 common car taillights states of normal operation,turn left,turn right and temporary brake.It has high practical value with easy manufacturing,low cost,energy efficiency and reliability.

Key words: digital logic;car taillights;intelligent control
