Have you ever seen signals blinking faster than they should? That’s hyper-flashing, a common problem for many vehicle owners. It is a clear sign that your vehicle’s indicators aren’t working properly. But don’t worry, the solution to this problem is much simpler than you think.
In this blog, we will discuss the reasons why LED hyper-flashing happens and how to quickly fix it. This will keep your vehicle safe and functional. So, keep reading!

1) Understanding Hyper-Flashing
“A condition where turn signals blink faster than the normal blinking interval is called hyperflashing.”
Hyper-flashing means that the rhythm at which your turn signal blinks is faster than the pace at which it is expected to operate. In other words, instead of flashing at a comfortable normal pace, they blink rapidly, almost like there is an emergency.

This problem usually occurs after changing regular bulbs to LED indicators. All the problems arise when LEDs use much less power than traditional bulbs. Because of this, the vehicle’s system gets confused.
Hyperflashing occurs when a vehicle’s turn signal system expects the electrical load that is needed for the traditional bulbs. But LEDs use much less energy, that is why the system gets confused and results in hyperflashing. Hyper flashing is mostly seen in older systems that aren’t automatically designed to work with or recognise newer technologies such as LEDs.
2) Common Causes
Now, it’s time to discuss the common causes of hyper flashing. Some common causes are listed below:
- Low Power Draw of LED Bulbs: Traditional bulbs consume more power than LED ones. A flasher relay is configured to detect the higher power input range. But when the flasher relay detects the low signals, it considers that the bulb is burnt out, so it starts to blink.
- Old or Standard Relay Flashers: Most older versions of vehicles have flasher relays which have been designed for incandescent bulbs. But these types of relays are not compatible with the lower LED power applications, so they cause hyper-flashing.
- Faulty or Loose Wiring: Faster blinking occurs if the wiring connected to your turn signal is faulty or loose. So, it can prevent the current flow.
- Improper Installation of LED Bulb: If the LED Bulbs are improperly connected, then they do not work correctly. So, the electric connection is disturbed, due to which the hyper flashing occurs.
- Burnt out Bulbs in the System: Even if you have changed to LEDs but if the rest of the bulbs in a circuit are still running on incandescent bulbs, it may still induce hyper flashing. This is due to the system calculating the total load instead of just one bulb.
- Mismatch Between Bulbs and Relays: Having two different types of bulbs in the same vehicle as one type installed on one side and LED on the other can confuse the flasher relay. Subsequently, causing an imbalance where one or both sides flash too quickly.
- Defective LED Bulbs: The defective LED Bulbs also cause problems because they might not match the right voltage, which leads to unstable flashing patterns.
3) Step-by-Step Solutions
Do not worry if you are facing the hyper-flashing. It can easily and quickly be resolved. There are some steps which can correct the hyperflashing. So, let’s discuss them step by step.

Install LED-Compatible Flasher Relays
Hyper flashing is caused by LED lights having less power consumption than incandescent bulbs. The easiest way to fix hyper blinking indicators is you install LED-compatible flasher relays. Just plug LED-compatible relays right into the connector with no wiring modifications. All that has to be done is remove the old relay and fix the new one.
Use Load Resistors
This method works well for many applications for those who could be considered non-technological changes. Fixing resistors between the positive and negative signal wire would allow one resistor to act as an incandescent bulb. Well, we can imagine, this will confuse the system to think there are several bulbs when in reality, only one is there. So, LED indicator stops flashing fast.
Check and Repair Wiring
Fast blinking turn signals could also occur due to a loose or damaged wiring connection. So, if your vehicle starts to hyperflash, you have to check the wiring. Then, the right wiring ensures that the correct signals reach the bulb and it helps to stop the hyper flashing.
Consider Reverting to Incandescent Bulbs
If you would like a quicker solution and do not wish to deal with changing relays or adding resistors, reverting to incandescent bulbs is also an option. These bulbs automatically have the correct load necessary for your car’s flasher system.
4) Preventive Measures
Preventive measures are also necessary to stop the hyper-flashing. In this section, we are going to discuss some important of them, so you should read it carefully and save your vehicle from hyper flashing.
a) Choose LED Bulbs Carefully
All devices require that you purchase top grade LED bulbs that are specifically manufactured for your vehicle. Purchasing low-quality or cheap LEDs will most likely lead to even bigger problems with excess LED flashing issues. Trusted brands mostly check their products to match the vehicles.

b) Use LED-Compatible Flasher Relays from the Start
You should use LED-compatible flasher relays from the start, it will prevents the hyperflashing of your vehicle from occurring before it even begins. It is an easy step which saves time and effort later.
c) Install Load Resistors Properly
For those who make use of load resistors, they should ensure that these components are properly installed. Improper installation can lead to things like short circuits or overheating. To assist with these types of issues, always mount resistors onto a metal surface. To do so, you can prevent them from overheating.
d) Regularly Inspect Wiring
Take the time to check your turn signal regularly. Check the damaged, loose or worn connections; if these are occurring, you should fix them immediately. By doing this, you can save yourself from the bigger problems which may happen in the long run.
e) Testing Signals After Installation
Once new bulbs, relays, or resistors have been installed, check the functioning of your turn signals without delay. This ensures that any flashing issues have been taken care of before you start driving.
f) Look Up Your Vehicle’s Manual
Certain modern cars may require additional adjustments when changing to LEDs. In case of doubt, always verify with your manual or consult with an experienced mechanic; some vehicles even offer pre-programmed settings to manage LEDs.
g) Do Not Combine Different Types of Bulbs
It is advisable not to use a combination of LED and traditional incandescent bulbs for a single circuit. Doing this may lead to system confusion and hyper-flashing. For optimum performance, stick to one style of bulb.
