How to Prevent Hyper Flash on Your Turn Signals | Lasfit Small Talk

[LASFIT]

If you're an enthusiast of modifications, you might know that installing aftermarket LED bulbs can sometimes result in hyper flash or even dashboard error messages. This issue is more common with aftermarket turn signals, tail lights, and brake lights.

The problem arises because aftermarket LED bulbs have lower power consumption compared to the original halogen bulbs. When the flasher relay detects a difference in resistance due to the different power consumption, it might mistakenly think the bulb is burned out and alert the driver through hyper flashing.

Lasfit has collected feedback from users who have faced hyper flash, and here are some solutions they have used:

1. Completely abandon aftermarket LED bulbs and switch back to OEM halogen.

2. Use load resistors to prevent hyper flash.

3. Choose bulbs with a built-in decoder or opt for higher power bulbs when purchasing.

Have you tried any of the methods mentioned above, or do you have other tips to share? Join the conversation and help fellow enthusiasts find the best solutions!

The average consumer without an Electronics degree, I think prefers Plug and Play.
No splicing or tapping of electrical wires.
No figuring out the correct wire on the vehicle.
I feel a resistor in a plug and play harness, is going to be the only solution, as of right now for the average owner.
And then there's always the price point. How much more will people pay to have the simplicity of a plug-and-play harness with an inline resistor?
Good luck,

I have only had hyper flashing show on my dash once with my Switchbacks. It was afternoon, I was in traffic and thus could not get out of the truck and look at the actual turn signal.
Therefore, I have no idea if it was an actual hyperflash or just an indicated one.

I agree Glenn!
As I have posted in another thread, newer cars are no longer simply "plug and play" when it comes to changing things electronically. Especially when it comes to lighting. It requires more work and like you stated, splicing, tapping, tweaking and figuring out which wire works and which doesn't. I tried the plug and play lamps in my 2015 Prius to only have either hyper flashing or melting happen due to LED's not being compatible. I also wound up making a hot mess of my wiring due to tapping.

Finally had to sink some serious money for aftermarket LED tailight assemblies that came with built in resistors. They worked, plugged in with no other adjustments needed and looked awesome. But I told myself I wouldn't do it again. Not worth the moolah.

On my 18 Buick Encore the headlights, front turn signals, rear tail lights, were all LED. The Encore being an international car the turn signals are separate and Amber but regular bulbs. I changed them out to LEDs never had a problem and boy were they bright. No one could say they couldn't see me turning.

It is my opinion. Turn signals should all be Amber and separate from your brake lights/ tail lights.
U.S. automakers will never adopt it, on there own
Unless the government steps in in legislates it. Just like seat belts, shoulder harnesses and airbags.

On my 2019 Explorer Platinum, it came from the factory with Led headlights and tailights. But not front and rear turn signals/parking lights.

I used led parking light/blinker bulbs that have a hyper flash error free chip from Amazon. They were half the price of my Lasfit led bulbs and still are available for the same price today on Amazon. I've had no issues with them at all hyper flashing physically or on the ipc in the 4 yrs they've been installed.

I put the the hyper flashing on the Maverick as a more of a ford maverick issue since it's not equipped with both led heads and tails. Hopefully someone will eventually come up with a better led bulb or fix via Forscan.
