Have you ever wondered why the turn signal besides releasing a “tick” sound when activated? It turns out that the sound of the turn signal is part of the development of this turn signal light. The turn signal is always a signal that is activated when the driver will turn. When activated, the turn signal will emit a “tick” sound repeatedly until it is turned off. Although not large, some drivers feel disturbed by the sound of the flashing lights. In the meantime, if your car’s appearance is damaged, then you can bring it to the most trusted auto detailing orlando near Orlando, FL.
Flashing turn signals began to appear on cars in the late 1930s when Buick put them on several models. Traditionally, the sound of flashing on turn signal lights is due to heat. In the initial version, the driver will turn on the turn signal and the electricity will heat the bimetal spring in the car which causes the spring to bend to touch the small metal.
The two components that are connected will be passed by an electric current and turn on the turn signal. The spring will cool quickly and return to its original shape and turn off the turn signal. When the spring bends and returns to its original shape it will create a “click” sound.
The next evolution of turn signal lights uses a similar trick. But instead of moving the spring due to heat, the latest system sends electronic pulses to an electromagnetic field through a chip. When activated, the electromagnet draws a wire coil and breaks the current that lights the light.
Without the pulse of the chip, the electromagnetic system is turned off. The wire roll will return to its previous position and bridge the circuit that gives power to the light bulb. As with thermal springs, wire coils will cause a “click” sound each time it is activated.
For newer models, most of the turn signal function become more computerized. Many cars produced today depend on computer commands that activate turn signal lights, skipping processes that produce “tick noise”.
