Where is the turn signal noise generated in your car?

Most cars have a mechanical flasher. The flasher consists of a peice of metal that heats up when the current passes through it. When it heats up, to bends, making that distinctive "tink" noise, The "tink" noise happens when the flasher breaks contact. The light flashes off and the metal cools. In just a second, it cools enough to "tink" closed and the light flashes back on. The heating process starts all over again.

When you have one or more lamps burnt out in the circuit, the flasher may not flash at all (there is not enough current flowing to heat the metal) or it may flash really fast in the case of a solid state flasher. This is your clue that you have a burnt out bulb.

Non mechnical flashers (solid state) must create the "tink" with a buzzer or sounder of some sort, since they otherwise work silently.

Car Turn Signal Sound

the turn signal works by the use of a flasher that usually is under the dash board. the clicking is the flasher turning the power on and off to make the lights blink.

It depends on the car, but on my Buick, the signal flasher unit is under the dash, clipped near the steering column about halfway between the steering wheel and the firewall.

It is a bi-metal strip consisting of two different metals that have a different expansion ratio. When current is applied,heat is generated causing the metal to bend and open the circuit.It then cools rapidly to close and starts the process over again.

it's kinda cool really. it is in your dash where there is this relay. it has these two metal strips that touch on one end and then they heat up making them curl away from each other. when they cool they straighten out again and touch where they start to heat up again. over and over again...this contact then breaking of contact makes the flow of electricity get interrupted making the light go off and on. and the clicking sound you hear is right there in the dash.

There is a live monkey living under your dash -- it taps the steering column with a small hammer when you use the turn signals.
