Blinker Blinking Fast

Blinker Blinking Fast ( Causes & 4 Steps To Fix )

Currently, a car will include many different types of lights: lights, signal lights, or warning lights. Each system will take on a specific role and coordinate smoothly during the movement.

However, when one of the lights fails, it will affect the safety of drivers around. The following article will help you determine what causes the Blinker Blinking Fast and how to fix them.

Basically, the turn light is an important part that cannot be damaged or malfunctioned. Because it directly affects the safety of the vehicles. You won’t be able to drive with a broken turn signal.

Because it will be a danger that you cannot imagine the consequences afterward. So figuring out what causes your turn signals to flash quickly is the best way to ensure everyone’s safety.

Why is my blinker blinking fast?

Why is my blinker blinking fast

To talk about the phenomenon of car lights having trouble, there will be many different causes. For example, the brake light stays on when the car is off, the lights won’t turn on, or the turn lights flash quickly. In particular, fast flashing turn lights are a common phenomenon that many drivers are experiencing. So what causes the flashing lights to fail?

# Power cord broken

After a period of use, the turn signal string will be old and maybe broken. Therefore, the entire lighting system will not be able to connect correctly, hindering the operation of the turn signal. So when does the turn light flash quickly? That is, when the power cord is about to break, the light signal will malfunction. Then, to test the turn signal system, you will need a multimeter or a test light.

# Insufficient voltage

Not supplying enough voltage is the next cause of fast flashing turn lights. The turn lights and some other connection conversion parts of the car will also have problems. Please try to replace the power supply to ensure the safety of the vehicle.

# The light bulb has a problem

A broken light bulb is a common reason that can cause the turn signal to flash quickly. Because resistance switches may fail after a period of use. As a result, the controller causes the light to blink continuously at a rate greater than rated.

# Relay related problem

A faulty relay is the following reason why the turn signal light is flashing at high speed. The root cause of this problem may be due to water entering and rusting the relay pins.

In addition, weak discharge relays can also cause directional light problems. So how to know if the relay is working correctly or not? You can rely on the “clicking” sound the relay makes when powering the lights.

# Turn signal fuse blown

A blown turn signal fuse is a relatively common cause of fast flashing turn lights. At this point, you need to check and make sure it is in top condition. If the turn signal fuse fails, you will need to replace it with the correct voltage and current.

Note: When you see fuses and relays inside the car or under the hood, you must check all of them and read the manual carefully. Because different locations will have additional requirements for fuses and relays.

How To Fix Blinking Turn Signal Lights

How To Fix Blinking Turn Signal Lights

To fix the fast blinking turn signal light, you need to do the following 4 main steps:

Step 1: Check the light

In step 1, you will need to get out of the car and check the blinking speed of the turn signal. You should check both the rear and the front. You would then turn the turn signal off and on again and check for any failed bulbs. Next, move further away to observe the speed of the bulbs. If all the balls work at the same speed, then there should be no problem.

Step 2: Repair the faulty bulb

In the event of a failed bulb, you will need to replace that number of damaged bulbs. First, you should open the bulb’s housing and take a close look at the bulb. You will need to open your hood to get the bulb.

Some vehicles will require you to remove the battery and air filter cartridge. The driver will then proceed to change the bulb.

Step 3: Check the relay

If you notice that all the lights are working fine, but the turn lights are still flashing, you need to have the relay checked. At this step, you need to listen to the relay sound and judge.

In addition, if you replace the bulb with a new one and it still doesn’t light up, it’s because one of the measuring relays is broken. Replacing the relay will require engineering. Therefore, if you are inexperienced, the best way is to call the emergency team.

Step 4: Check the connection wire

After the above 3 steps, you need to check the connection wire if you still haven’t found the cause.

Usually, the connection wire can be damaged or broken. At this point, you will need to test each wire along with all the connectors. When you find faulty cables, try to fix them by reconnecting or replacing them.

Some Frequently Asked Questions

How to check the turn signal relay?

To check the turn signal relay, you need to find its location in your car. You should prepare the instruction manual because it will help you find the relay easier. Then you need to check the wiring of each relay to make sure everything is working correctly.

What is an LED relay?

Led relay is a power supply device for car led lights. All emitters are built in the form of an integrated circuit, acting as a semiconductor. The lights emit diodes based on the car’s programs or do so sequentially.

Is blinking fast-turn lights illegal?

Fast flashing lights are against the law. Specifically, a lot of people have been penalized for this error. For example, on 12/12/2013 in Georgia, each police officer fined a driver when his flashing turn lights were operating at high speed.

Conclusion

Hopefully, the article will help you better understand what causes the turn lights to flash quickly. To fix that situation, you will need to perform 4 steps sequentially.

Also, when checking relays and fuses, you should prepare your car’s manual. Because that’s the best way for you to control all the relay and fuse positions.
