Automotive lighting systems can be affected by hyper flashes. A surge of electricity can cause the headlights to emit a very bright light. The problem needs to be fixed as soon as possible if this occurs.
The problem with these solutions is that they generally require the use of resistors to decrease the LED’s intensity, which can result in overheating and interference with other circuit components.
So, keep your system running smoothly with this blog post on how to fix hyper flash without resistors.
What Is Hyper Flash?
LED headlights are generally prone to hyper flashes. Due to a failure in the driver IC, the LEDs cannot handle the current flowing through them.
In this case, a large number of current flows through the LEDs, causing them to flash quickly before shutting down.
Hyper flashing lights may cause serious accidents because other drivers are highly distracted.
Furthermore, law enforcement officers might pick on more people using them than those without such flashy signals, which could cost you fines.
Why Does Hyper Flash Occur?
The first possibility is that the LED bulb may fail to turn on because it is installed in a circuit designed for incandescent bulbs rather than more modern LEDs.
The mismatch between systems causes CANBus to return an error, which causes hyper flashing.
Alternatively, it could just draw less power than an incandescent, which will drain less power from your car’s electrical system.
As a result, when someone fixes something as simple-looking as turn signals, it goes unnoticed by someone who isn’t paying much attention.
How To Fix Hyper Flash Without Using A Resistor
There are several ways to fix hyper flashes without a resistor, including replacing the electronic flasher or using a thermal flash relay.
Rather than investing in an expensive and time-consuming plug-and-play load resistor harness, you can opt for the methods below.
1. Your Electronic Flasher Needs To Be Replaced
The flasher system likely is to blame if you have hyper-flashing issues with your lights. However, any problems may arise from dirty contacts or corrosion- which can be resolved by replacing these components.
If you’re not sure, check your car’s hood. If it’s not rusted, everything should be shiny. To find the right replacement flasher for your car, consider the following factors:
- The new flasher’s voltage rating
- The new flasher’s amperage rating
- Whether the flasher is normally open, normally closed, or latching
Remove your old flasher and install the new one after determining the correct replacement flasher for your car. It is important to ensure the new flasher’s voltage and amps match the old ones.
2. Make Use Of A Thermal Flasher Relay
Thermal flasher relays prevent hyper flash. The factory relays are specially designed for incandescent bulbs and are similar to old-school plugs in that they can be adapted fairly easily with no modifications or additions required by the end user.
With a thermal flasher relay, hyper flashes can be fixed without using resistors. There is a relatively easy installation process for this device, and it can be found at most automotive parts stores.
Thermal flasher relays regulate the current flowing through LEDs, preventing the headlights from flashing excessively.
Since these modules don’t get hot enough to cause hand fatigue, you won’t have any problems – perfect timing considering you’ll probably be doing lots of other things before coming back.
3. You May Need To Adjust Your Resistance And Draw Requirements
If you have aftermarket car computer software, you can change the resistance and draw a turn signal to fix your ECU control system.
If you try this first before wasting time on something else, you can mitigate hyper flashing and error messages. However, this may not work for all vehicles.
4. A Capacitor Can Be Used
In cases where resistors and thermal flasher relays cannot fix hyper flashes, capacitors may be used. LEDs can be prevented from flashing too rapidly by using a capacitor to regulate the current flowing through them.
However, the right capacitor for your car must be chosen from various options. If you want to know which capacitor is right for your car, consider the following:
- Defining the capacitor’s voltage rating
- The capacitor’s capacitance
- Capacitors can be electrolytic, ceramic, or film types.
How Do Capacitors Work?
Electrolytic capacitors, ceramic capacitors, and film capacitors are the three types of capacitors. Several applications, such as automotive electronics, use electrolytic capacitors, the most common type.
RF (radio frequency) circuits use ceramic capacitors as the second most common type of capacitor. Film capacitors are the least common and are used in various applications, including high-frequency circuits.
An electrolyte separates two plates in an electrolytic capacitor, which is an older type of capacitor.
Ceramic capacitors are newer types of capacitors that consist of two plates separated by a ceramic material. There is a greater capacitance in the electrolytic capacitor than in the ceramic capacitor.
How Do AC and DC Flashers Differ?
AC and DC flashers are two types of electronic flashers. Choosing the right one for your car is important since they have different operating voltages.
AC flashers operate on 12 volts and are the older type of flasher. DC flashers are newer types of flashers that operate at 24 volts. Thus, DC flashers are more common than AC flashers.
How Do Electronic Flashers Work?
Transistors switch on and off the current in electronic flashers. There are three different configurations of this type of flasher:
- N/O (normally open)
- N/C (normally closed)
- (L) latching
It is the most common type of flasher, and most vehicles use it. In some vehicles, the normally closed flasher is used, while the latching flasher is used in others.
You must select the right one for your car based on minor differences, such as the amount of current they can handle. For example, when a car uses a normally closed flasher, the normally open flasher will not work.
What Can I Do To Stop My Indicators From Flashing Fast?
You can take a few steps to prevent your indicators from flashing excessively. To reduce the speed at which your indicators flash, follow these steps:
- The old flasher should be removed from the car
- The positive lead of the multimeter should be connected to the positive terminal of the flasher
- The negative lead of the multimeter should be connected to the negative terminal of the flasher
- Make sure the multimeter is turned on
- Multimeter readings should be close to zero. You’ll need to replace the flasher if it isn’t.
- Make sure your car has the right capacitor
- LED bulbs should be connected in series with a resistor
What Can I Do To Prevent Hyper Flash?
Hyper flash can be prevented in a number of ways:
- Make sure you use the right flasher for your car
- Make sure your car has the right capacitor
- LED bulbs should be connected in series with a resistor
Installing a resistor in series with the LED bulbs is the easiest way to prevent hyper flash. This way, the LED bulbs will be limited in current flow, preventing hyper flashing.
Is Hyper Flash Illegal?
Drivers are at risk of a traffic accident when they encounter hyper flashes, which can pose a safety hazard to other drivers.
Therefore, many states have laws prohibiting hyper flash. To comply with the law, your car’s lights must be visible from at least 500 feet away.
Turn signals must flash a minimum of 120 times in a minute, according to the transportation department. So hyper flashing can already violate the law if you have a problem with it.
It is possible, however, for manufacturers to create a headlight that hyper flashes. While it is legal in this case, some drivers may have difficulty.
Check to ensure your vehicle is not hyper-flashing more than one hundred (120) times when you think yours is.
The Bottom Line
Hyper flashes without resistors can be fixed by using the right flasher, selecting the right capacitor, and wiring a resistor in series with the LED bulbs. Following these same steps can also stop your indicators from flashing too fast.
The flasher may need to be replaced if you are still experiencing problems with your hyper flash. Indicators flash when the flasher is functioning correctly, and it can be replaced if it is not.
