Car Flasher: Types, Functions and How to Use It

The car flasher is one of the components in the vehicle that serves to supply electric current to the changing turn signal lights. The car flasher function makes the lights appear flashing.


In addition, the flasher functions as a turn signal light. If you are going to turn left, then you have to notify the driver behind or ahead with a car flasher.


Car Flasher Function


The flasher function on this car is very important, because it prevents accidents when you turn. The flasher also functions to notify the driver who is in front or behind.


In the car flasher circuit, there are components in the vehicle that regulate so that the turn signal lights can be seen flashing. This car flasher circuit supplies electric current to the changing lights, so that the turn signal lights can be seen flashing.


This way other drivers on the highway can tell whether you are turning right or left. So that other drivers can give your car a distance and accidents can be avoided.


How the Car Flasher Works


To find out how a car flasher works, you must first know that a car flasher has several supporting components.


The car flasher circuit that becomes the supporting component starts from the output current. resistor, contact point. elco, or capacitor, coil 1, coil 2, and battery.


Well, the way the car flasher itself works, there are several types, namely the type of transistor, the type of contact point, and the type of capacitor.


For the capacitor type, the flasher light can flash automatically because the electromagnet is automatically regulated by the capacitor.


As for how a car flasher works in general, the function of a car flasher is to regulate the blinking of the turn signal, namely when the contact point is positioned ON, an electric current will flow through the touch point and coil.


So that the electric current will fill the capacitor, where at the same time the iron core in coil 1 will become a magnet and then attract the contact point.


This will make the contact point open, and the flasher light turns off. When contact point P remains open, capacitor C begins to discharge.


So that the charge in the capacitor is reduced, then the contact point P closes due to spring pressure. After the contact point P closes, the current then returns to the L1 and L2 coils.


Then the capacitor will be charged again, because the amount of electric current in the L2 coil decreases. The movement of the L1 coil causes the contact point P to open, so that the F1 and F1' turn signal lights and the PL pilot light turn off.


The relay on this electrical circuit makes the turn signal appear flashing. That's how a car flasher works. The existence of the turn signal on the vehicle is very useful, so that accidents between motorists on the highway can be avoided.


If the flasher is damaged, the coil will not be able to create a relay. so the turn signal does not flash when the lever is turned on.


Therefore, maintenance of one of the components in this car is very important to do. And you have to find a way to fix a broken car flasher.


How to Use Car Flasher


How to use a car flasher is actually easy, you just have to activate the lever in the steering area. Then automatically, the flasher will flow an electric current to the turn signal so that the lights in that section are lit at the same time blinking.


Then, you can also set your own left and right turn signal that you want to turn on. It all depends on which direction you want to turn.


The location of the car flasher is usually under the car's steering wheel. But in some cars it is also different, the location of the car flasher is usually on the side. So to take it, it is not uncommon to have to disassemble the side of the car.


Flasher Maintenance and Repair


Considering the function of the car flasher is very important, then all you have to do is take care so that the flasher is not easily damaged.


But if you are unlucky, and already there is a problem with the turn signal, then you inevitably have to fix the car flasher.


For that, here's how to fix the following car flasher that you can try:


  1. How to fix a broken car flasher if both turn signal lights don't turn on, try checking the ignition, fuse, and flasher. Most likely there is damage to the three parts.
  2. If all the turn signal lights are on but can't flash, then the flasher is definitely having a problem. You can check the state of the ignition to the wires.
  3. If the turn signal lights sideways but does not flash, check the turn signal switch section. How to fix a dead flasher, check the connection of the lamp in question, it might be loose, dirty, or rusty.
  4. If a turn signal does not come on, then the problem is most likely not with the flasher. But on the lamp itself, the filament may have broken so it must be replaced with a new one.

It is also necessary to know the signs that the flasher functions to create a flicker of the turn signal when it is turned on.


If your turn signal light is on but not flashing, it means that the flasher is faulty.


However, if the problem is that the lights don't turn on, then it could be because the lights are faulty.


If the turn signal is damaged such as not blinking or completely dead. Then it could be a short-circuit flasher. The cause of the car flasher caught fire the coil of wire received excessive stun.


And the short circuit can be connected or not. So that the stun condition may still flow or not at all. So the turn signal can be bright or completely dead.


If the flasher is totally dead. So how to fix a dead flasher, of course it's better to replace it with a new one.


To help the next handler, you can take the car to the repair shop. This is because only technicians know how to install the correct car flasher.


This is of course to prevent the occurrence of a flasher that does not turn on due to loose components. So even if you understand how to install a car flasher, it will be much better if it is handled by a professional.


Vehicle Flasher Type


Types of vehicle flashers, both cars and motorbikes, are divided into 3 types. All three are distinguished by the car flasher scheme.


The three types have different circuit structures. But the main function remains the same. Well, here are some types of flashers that are on the vehicle.


1. Bimetal Car Flasher


The first type of flasher is a Bimetal flasher. This type is a type of flasher with the simplest car flasher scheme compared to other types. Where in this type, there are at least 2 metal rods of different lengths.


The way the Bimetal car flasher works is when the flasher is cold, the metal rod contacts will be connected so that the electric current from the battery will flow.


Well, when there is an electric current, the bimetal heating process will occur. This bimetal heating and cooling process is used to disconnect and connect the electric current to the load.


So that the load from the flasher itself is a turn signal and also a hazard so that the light will flash when an electric current flows through the flasher.


2. Transistor Flasher


Next is the transistor model flasher, this model is widely used by the latest cars and motorcycles.


The way it works is that the transistor flasher uses an electronic system controller. So that it no longer uses a mechanical system for contacts.


The components used are multivibrator oscillator. In its use, these components are used to generate a constant pulse signal which will be sent to the flasher by passing through an electric amplifier.


And that's when the turn signal lights will flash in accordance with the constant pulse of the flasher.


3. Capacitor Model Flasher


The last is the type of flasher capacitor model. In this type, the working system is almost the same as the transistor flasher type, which is no longer using a mechanical system but already carrying an electronic system.


The flasher scheme for this capacitor model car will function when there is an electric current from the battery when the contact is in the ON position. It's just that at that time the current condition is not directly connected to the load but will only flow to terminal L2 through the contact plate P.


And at that time, the current is still accommodated in the capacitor component. And when the position of the turn signal switch is ON, the current will flow directly to the L1 flasher leg and then exit to the load, namely the turn signal. So the light will turn on.


When L1 gets current it will automatically become a magnet and the contact plate P will automatically open and will pass through the resistance R. And at that time the condition of the contact plate will remain open until the current in the capacitor runs out.


The difference between a car flasher and a motorcycle is only in the wattage. In terms of shape, the difference between a car and a motorcycle flasher is that the motor flasher generally uses a flasher with pin two while the car flasher with pin 3.


But now the pin 3 flasher has also been used by the motor. So that the difference between a car and a motorcycle flasher may be one of the prices of the respective car and motorcycle turn signal flashers.


Usually the price of a car turn signal flasher is slightly more expensive with a motorbike. This is because the car flasher has a power level that is able to turn on 4 bulbs at once. The price for a car turn signal flasher could be much higher.


Tips from Auto Insurance Agencies! To ensure that every component of your car, including this car flasher, functions optimally, always check your vehicle regularly. Ensuring that each component functions optimally prevents you from the risk of accidents.
