This is a replacement turn signal flasher module. It will eliminate fast turn signal blinking, known as hyperblinking, that occurs when you replace your turn signal bulbs with LEDs. It has been designed specifically for use with LEDs.

This module is specifically for your vehicle! It will be 100% plug and play. Just remove the factory flasher, and plug this one in.


Why do you need this module? When your factory turn signal bulbs go out, your vehicle's flasher senses that less power is being used, and it will blink the turn signals quickly to alert you. When LED turn signal bulbs are installed, it lowers the load on the circuit too, because LEDs use less power. You get the fast blinking, known as "hyperblinking," even though the LEDs are functioning just fine. Basically, your car thinks the bulbs went out!

To slow down the blinking to regular speed, you can add resistors to increase the circuit's power consumption again. However, whenever possible, replacing the flasher with a module like this is the easiest option. This is the unit that actually controls the blinking speed, and makes the "clicking" noise.

  1. Good price, good product Review by Chris

    I'm not sure if I needed this, but I got it just in case as many forums noted that it was necessary. Getting the old one out was a pain but this wasn't plug and play. This flasher had extended prongs that prevented it from fitting, so I just cut off the excess and it fit perfect. No hyper flashing and sounds better too! (Posted on 6/24/15)

  2. No more super flash! Review by Gabe

    Bought front and rear led bulbs for the blinkers and at first thought it might not be that bad. Tried them out and instantly decided to go ahead and install the new relay. Hyper blink was so fast it was borderline annoying. Now it looks nice and factory pace again. (Posted on 4/18/15)

  3. Works as intended!!! Review by Andy

    Received product in perfect condition. A bit confused at first to find the location of the OEM relay, but with the help of Google directing me where to find it, it was smooth sailing from there. A bit difficult to get to due to the limited space to work with but the reward is well worth it. There is a "hang" delay for about a second when you flip the turn signal. Other than that it works like a charm and good riddance for the "hyper flashing"!!! (Posted on 12/7/14)

  4. It works! Review by Havok

    At first I didn't care about the hyper flashing but then it just annoys you to death. Simple plug and play and you are good to go! (Posted on 9/9/14)
