[0002] Turn signal is an important indicator light that turns on when a motor vehicle turns to alert vehicles and pedestrians in front, behind, left and right. Turn signal lamps use xenon lamps, and single-chip control circuits, and work continuously with left and right strobing. Turn signal lamps use flashers to achieve light flashing. They can be mainly divided into three types: resistance wire type, capacitor type and electronic type.
