Where does the car signal light sound comes from?

Question

You know, every time you put on the left or right turn signal, there will be this "tip-tap-tip-tap" sound until you actually turn and steer the steering wheel back to it's original position then it automatically stops.

There's like no speakers or anything but the sound is very prominent...

What makes the sound really and where does it come from?

Answer 1

There's a little flasher unit that's mounted at the fusebox. It controls the lights and provides the audible warning that the turn signal is operating. That's from where the noise is originating. You can see it if you look under the dashboard and locate the fuse box. It is usually a small silver-colored cylinder or box-like metal thing that is plugged in at the box.

Answer 2

There is a relay switch(signal flasher) in the vehicle that controls the turn signal in your car. The clicking you hear is the relay activating and deactivating thus turning the light on and off. The clicking in the steering wheel is part of the switch that once the steering wheel is turned past a certain point it releases the switch which in turn turns off the relay.

Answer 3

Worldwide regulations stipulate an audiovisual telltale when the turn signals are activated; this usually takes the form of one combined or separate left and right green indicator lights on the vehicle's instrument cluster, and a cyclical "tick-tock" noise generated electromechanically or electronically. It is also required that audio and/or visual warning be provided to the vehicle operator in the event of a turn signal's failure to light. This warning is usually provided by a much faster- or slower-than-normal flash rate, visible on the dashboard indicator, and audible via the faster tick-tock sound.

Answer 4

The clicking noise comes from the signal flasher. This item is normally contained in your fuse panel and actually controls the on - off flow of electricity to the signal light bulbs.

Answer 5

The clicking noise come from the Thermal flasher unite as current is passed through it and as for the turn signal shutting it's self off most newer model cars are equipped with a unit that actually shuts the signal off after the turn is complete.

Answer 6

well honestly, theres not one correct answer for every single car, in for exapample, a bmw like mine, its very loud, in fact, it echoes, but that, is the actuator, it lets you know its on, if one is out, all the power goes into the other actuator, so it clicks extra fast, if the little click sound is gone, or less loud, like in for say, a modern luxary car, it has a better technology than my 80s bimmer. so some most cars, have something like that though not all, some, it actually has a speaker, remotely mounted, some, im not sure

Answer 7

like the others have stated- verify your connections, sparkling terminals, verify fuses, if battery cable is broken- you would be able to would desire to cut back and replace it. Have the battery checked with the aid of an motor vehicle electric powered save, the climate save provides you a faux examine just to sell you a sparkling battery ( I basically had this ensue to me) If those form of issues fail- purely for the heck of it, faucet your starter with a crow bar or steel merchandise, this might wake the starter motor up tempararily to commence the motor vehicle. sturdy success !

Answer 8

It is the blinker relay switching itself on and off to make the light flash. Normally under the dash on th driver's side.

Answer 9

It is an assembly that is called the turn signal flasher.Sometimes it is integrated into the hazard switch.

Answer 10
