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.

I got this flasher module on recommendations to install this to prevent hyper flashing. I installed the bulbs first and they definitely hyper flashed. it's kind of cool, loud. there's no chance you would accidently leave on the turn signal. it's loud when it hyper flashes. HOWEVER-this is the bad news. this module does not fit my vehicle (2013 Kia Forte sx) DIODE DYNAMICS included a set of jumper wires in the event that they would be needed. on the way back from a Chicago trip I was going over blog posts to learn how and where the flasher was on my car and how to change it. it's under the dash, way up and you will for sure be in a strange position to get it in and out. the blog posts I read all noted that DD has the wrong size module for this fitment. it IS the correct number and model in that the one I got is an EP 34 chip, however this one is too large to fit in the socket (the plastic housing on the chip is too wide) the blogs noted to get a TRIDON EP34 chip which is available locally, a bit more expensive but not more thann3$ more, this chip is a tiny bit taller but the exact width of the modules slot in the dash. I am not faulting DD on this as in a correspondence with DD staff they did notify that this specific car model has not been in the shop for testing. they included the jumpers in case one would need to place the chip in using them, however there is not enough room in the dash above the chip to use this. again I am not faulting DD for this. in fact I applaud the gesture and forethought on their part to try to cover all bases. kudos. the part number is the same that comes up in many searches "EP 34". i got the correct one and it works. It would be nuts to expect a business to have seen EVERY model car in production in their shop to make sure every part fits perfectly. I'm sure that the longer these kind folks are in business (and I hope that's a long time) more and more model cars will be added to the database as tested for perfect fitment. great company. will definitely order the remainder of my lights from DD (Posted on 7/15/16)
No More Hyper blinking ! Review by Darin

This is by far the easiest way to fix Hyper blinking after installing LED Switchbacks. The hardest part is not actually installing the new flasher. It plugs right in to the existing port. The Hard part (And I mean Hard) was getting the old stock flasher out. You have to lay with your head down by the pedals and reach up under the dash/steering wheel to get access. The angle is hard and the stock flasher clips and locks in place so you have to squeeze the clips while pulling it up in a very tight space. Just have patience and slowly work it until it comes loose. So happy with this product. My switchbacks function perfectly now. Thanks Diode for yet another great way to customize.
