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!

My issue started when my 2024 be was replaced with a 23 bed that had the upgraded LED turn signals already installed, plug and play is what the shop did. Where would I need the resistor installed at on the truck? Where can I get the resistors at for this application? Appreciate the help.

I've found Load Resistors to be very easy to install and work perfectly to eliminate hyper flashing.

I found that on my Challenger when I added clear corner markers with Amber/Red LED blinkers, and on Wifey-pooh's ND Miata when I swapped all her corner & side markers for LEDs and her rear tailight blinkers for Sequential LED panels, that I only had to install one Load Resistor into the wire harness at one of the blinker locations and it worked to "steady the ship" for the whole car. A load resistor wasn't needed at each blinker for either car..probably wouldn't hurt to add one at each location, but I found they seem to "globally" fix the hyper flash.

Load Resistors are easy to install. You can splice it into a blinker signal wire or just piggy back the LR over/into the signal wire with a T-clip that often comes with the LR. The LR connector to the hot signal wire on one end and then to the ground wire on the other end..it basically puts a "drag" on the power routing making the LED seem like it's drawing more power just like the incandescent bulb did..easy peasy!

Here's a link to Amazon (Walmart has the same ones) for a Sylvania pair of LRs. There's a quick little instructional video to see how easy peasy installing a LR is.

Thank you for your input on this.

The part messing me up, the hyper flash isn’t at the corner signals, it’s only the lights mounted on the mirrors. I’m assuming I only need LRs for the mirrors. Is my assumption correct? I appreciate your feed back.
Thank you again.

Yes, that is correct.
